Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laboratories, and particularly relates to a high-throughput parallel chemical reaction device with modular design. Background Art
[0002] The high-throughput experimental technology originated in the 1980s and has since developed rapidly in the field of biological science experimental technology. Especially with the rapid development of laboratory automation technology, it has greatly promoted biological science research such as high-throughput gene sequencing, high-throughput cell screening, high-throughput nucleic acid virus purification, high-throughput synthetic biology, and high-throughput ELISA detection.
[0003] The basic principle of high-throughput experimental technology is to conduct multiple experiments (usually dozens, hundreds, or even thousands) simultaneously in a parallel processing manner to explore the relationships between various variable parameters. Today's high-throughput experimental technology is developing towards the direction of "automation, miniaturization, and scale-up", aiming to obtain "the most data" with "the fastest speed, the highest efficiency, and the lowest cost", and this goal is also closely combined with the current scientific trends of artificial intelligence and machine learning. Specifically for high-throughput chemical synthesis technology, it usually requires "conducting hundreds or thousands of parallel chemical reactions simultaneously in 1-2 ml reaction tubes (such as 96 or 384-well plate mode)", so that the cost of a single chemical reaction can be minimized (with the least amount of reaction raw materials), and the chemical reactions are operated automatically, thus greatly improving the speed and reducing the time cost to the lowest level.
[0004] The high-throughput test method based on porous plates (24 / 48 / 96 / 384-well plates) in accordance with the SLAS / SBS standard specifications is common in the field of biological high-throughput, with low cost and easy implementation. However, it is extremely challenging in the field of chemical synthesis: Firstly, the chemical reaction conditions are much more severe than those of biological reactions. Most biological high-throughput experiments are under mild experimental conditions, and the commonly used 96 / 384-well plates are usually made of "plastic material" that is biocompatible and simply cannot meet the usual "high temperature and high pressure" experimental conditions of chemical reactions. Most high-throughput chemical reaction experiments are under severe experimental conditions and require to be carried out in glass reaction tubes with "temperature and pressure resistance", and the glass reaction tubes need to be placed in an aluminum metal block to meet the temperature control requirements of "rapid and uniform heat conduction". Secondly, the physical and chemical properties of chemical reaction reagent materials are also very different from those of biological reaction reagent materials. Biological reactions are usually carried out among aqueous biological reagents, with the characteristics of "single homogeneous phase, very low viscosity, easy mixing, and short reaction time"; the characteristics of chemical reactions are "multiple phases with solid-liquid coexistence, high viscosity, strong stirring and mixing required, and long reaction time". Therefore, the commonly used "oscillation mixing and aspiration mixing" in biological high-throughput experiments cannot meet the experimental requirements of high-throughput automation of chemical reactions.
[0005] Today's chemical reaction technology is far from reaching the true high-throughput experimental level. It still remains at the stage of "simultaneously conducting several parallel reactions", and usually conducts experiments at the level of "reaction scales from dozens to hundreds of milliliters". This is far from the goal of "modern high-throughput chemical experiments": firstly, the number of single experiments is too small, resulting in "slow speed and low efficiency"; secondly, "the scale of a single reaction is too large", leading to "high consumption of raw materials and high cost for each reaction". These cannot meet the goal requirements of large-scale machine learning for "low-cost big data".
[0006] Currently, technologies and devices with a truly modular high-throughput chemical reaction device are extremely rare. More or less, there are some problems with similar parallel chemical reaction devices. For example, the utility model patent with the authorization number CN 220371009U discloses "a photochemical parallel reactor device", which usually can only conduct parallel operations of less than 10 photochemical reaction experiments at a time, and the scale of a single reaction is all above "30ml reaction tubes"; the utility model patent with the authorization number CN 215611455U discloses "a parallel reactor", which usually can only conduct parallel operations of 10 chemical reaction experiments at a time, and the scale of a single reaction is all in "25ml Schlenk reaction tubes"; the invention patent with the application publication number CN 111167361A can achieve "simultaneous magnetic stirring of 0 - 200 small-capacity liquids of 5ml to 20ml, and many sets of stirring experiments can be done at one time, and precise and stable stirring can be carried out, and precise gradient temperature control can be achieved, with a wide temperature range of use (-20°C to 100°C)". However, this design is extremely complex. Due to physical space limitations, the 5ml glass tube is already the limit, so it is impossible to meet the high-throughput automation requirements of a "96-well 1ml glass tube reaction block" laboratory, and its large volume is also difficult to integrate into an automated experimental platform; the invention patent with the application publication number CN 118076439A discloses a device of "an integrated system for chemical, biochemical or molecular biology reactions in a microplate", and the content includes "uniformity high-precision modular temperature control" technology, but it is only suitable for mild biochemical reactions and not suitable for high-throughput chemical synthesis reactions.

[0061] The electrode mounting substrate 304 is arranged corresponding to the metal heat-conducting block base 301 at the top of the first reaction bottle 302. One end of a plurality of electrodes 305 is mounted on the electrode mounting substrate 304, and the other ends respectively extend into the corresponding first reaction bottles 302. The electrodes 305 are externally connected to a multi-channel DC or AC power supply through the electrode control bus 306.
[0062] As Figure 4 、 Figure 5 shown, the light source module includes a dot matrix light source board 403, a light source control bus 406, and light source lamp beads 408.
[0063] The photoreaction sample tube module includes a metal base 401, the metal base 401 is arranged on the dot matrix light source board 403, a plurality of second reaction bottles 402 are placed on the metal base 401, and a strong magnetic stirrer two 404 is placed in each second reaction bottle 402. A light source lamp bead 408 is arranged on the dot matrix light source board 403 at a position corresponding to each second reaction bottle 402, and the light source lamp bead 408 is used to irradiate the chemical reagent in the second reaction bottle 402.
[0064] Optionally, the metal base 401 is internally provided with a first microporous channel, and a coolant inlet and outlet 405 is arranged on the side wall of the metal base 401. The coolant inlet and outlet 405 is used to introduce a heat-conducting or heat-conducting fluid, and the heat-conducting or heat-conducting fluid controls the temperature of the photoreaction in the second reaction bottle 402 through the first microporous channel.
[0065] The dot matrix light source board 403 is internally provided with a second microporous channel, and a coolant inlet and outlet 405 is arranged on the side wall of the dot matrix light source board 403. The coolant inlet and outlet 405 is used to introduce a coolant, and the coolant enters the second microporous channel to cool the light source lamp bead 408.
[0066] Specifically, the dot matrix light source board 403 of the light source module is assembled with light source lamp beads 408 of various wavelengths according to Figure 4 、 Figure 5 shown. The coolant enters the second microporous channel to cool the light source lamp bead 408 and takes away the heat generated when the light source lamp bead 408 works. One or more light source lamp beads 408 are externally connected to a power regulator as needed to achieve real-time adjustment and control. The bottom of the metal base 401 penetrates or is provided with high-transparency quartz glass or similar materials at a position corresponding to the second reaction bottle 402 to ensure that the light source lamp bead 408 of the light source module can perform a light reaction on the chemical reagent in the second reaction bottle 402. The first microporous channel built into the photoreaction sample tube module can introduce a heat-conducting or heat-conducting fluid to ensure precise temperature control of the photoreaction.
[0067] Optionally, the temperature control module 2 includes a temperature control base. A plurality of temperature control bases are located directly above the vertical magnetic field generation module and are arranged in sequence along the direction where the vertical magnetic field generation module is located. The temperature control base is connected to a temperature controller.
[0068] It should be noted that the temperature control module 2 adopted by the present utility model can perform temperature-controlled chemical reactions, and can also heat or cool the electrochemical reaction module 3 and the photoreaction module 4. The temperature control module 2 adopts the existing technology, and it can be heated by the principle of resistance wire heating. When refrigeration is required, ice water can be introduced into the temperature control module 2 to achieve the refrigeration effect. When the temperature control module 2 adopted can perform temperature-controlled chemical reactions, the sample reaction tube module 5 needs to be placed on the temperature control module 2, and then the sample tube is installed at the corresponding position in the sample reaction tube module 5. A strong magnetic stirrer (not shown in the figure) is also placed in the sample tube.
[0069] Optionally, the outer dimensions of the sample reaction tube module 5, the metal heat conduction block base 301 and the metal base 401 are the same as the orifice plate dimensions of the SLAS / SBS standard, and their interiors are all designed in specifications of 96 holes of 1 ml, 48 holes of 2 ml, 24 holes of 4 ml or 8 ml.
[0070] Specifically, the sample reaction tube module 5, the metal heat conduction block base 301 and the metal base 401 are processed from metal aluminum blocks or other metal materials with excellent thermal conductivity. Their outer dimensions are the size of the orifice plate of the SLAS / SBS standard (about 127.6 mm x 85.4 mm) to ensure compatibility with commercial platforms. The metal heat conduction block base 301 and the metal base 401 are processed into a 96-hole plate that can accommodate 1-ml glass reaction tubes, a 48-hole plate that can accommodate 2-ml glass reaction tubes, a 24-hole plate that can accommodate 4-ml or 8-ml glass reaction tubes (with the same diameter), etc. according to requirements. A micro stirrer magnet of a suitable size is placed in each reaction tube. Driven by the strong vertical rotating magnetic field of the vertical magnetic field generation module in the vertical magnetic stirring and mixing platform 1, the magnet in the reaction tube is driven to rotate, achieving the effect of stirring and mixing. Figure 2 and Figure 4 Shown is the structural diagram of a 24-hole plate that can accommodate 4-ml or 8-ml glass reaction tubes (with the same diameter).
[0071] As Figure 6 shown, the vertical magnetic field generation module includes a magnetic pole group and a fixing frame 102. The fixing frame 102 is arranged outside the magnetic pole group and is used to fix the magnetic pole group. The magnetic pole group includes a connecting frame 103 and one or more magnets 104. The connecting frame 103 is arranged inside the fixing frame 102 and is parallel to the plane where the bottom surface of the temperature control module 2 is located.
[0072] If the number of magnets 104 is one, one magnet 104 is fixed on the connecting frame 103 alone.
[0073] If the number of magnets 104 is multiple, multiple magnets 104 are evenly fixed on the connecting frame 103 at equal intervals. The connection line between the two magnetic poles of each magnet 104 is perpendicular to the bottom surface of the temperature control module 2.
[0074] Optionally, a driving module is further provided inside the vertical magnetic stirring and mixing platform 1. The driving module is connected to the vertical magnetic line generating module and is used to drive the vertical magnetic line generating module to rotate within the plane of the bottom surface of the vertical temperature control module 2.
[0075] Optionally, the driving module includes a driving motor 105, a coupling 108, and a speed controller.
[0076] The output shaft of the driving motor 105 is connected to the connecting frame 103. The speed controller is connected to the driving motor 105. The connecting frame 103 is connected to the output end of the driving motor 105 through the coupling 108.
[0077] Optionally, the vertical magnetic stirring and mixing platform 1 further includes a main control screen 101, and the main control screen 101 is arranged on the front surface of the vertical magnetic stirring and mixing platform 1.
[0078] In this embodiment, the main control screen 101 is connected to the driving motor 105 and is used to adjust the rotation speed of the driving motor 105, so that the strong magnetic stirrer one 303 and the strong magnetic stirrer two 404 are suspended in the sample. The driving motor 7 can be a horizontally arranged rotary motor. During actual use, the rotation speed of the driving motor 105 can be adjusted through the main control screen 101 according to the viscosities of different samples.
[0079] The vertical magnetic stirring and mixing platform 1 uses a neodymium iron boron magnet with a high magnetic energy product and good high-temperature performance as the magnetic pole of the magnetic pole group, and maintains the distance between the driving motor 105 and the magnetic pole group through the coupling 1088, which can effectively avoid the interference of the magnetic field of the driving motor 105 on the magnetic lines.
[0080] In order to achieve a better sealing effect and prevent the sample in the reaction bottle from leaking out of the bottle mouth, a first sealing cover 307 and a second sealing cover 407 can be respectively arranged at the bottle mouths of the first reaction bottle 302 and the second reaction bottle 402.
[0081] The high-throughput parallel chemical reaction device with modular design provided by the present utility model can be freely combined and modularly assembled as required to carry out various high-throughput chemical reactions. For the stirring and mixing of various types of chemical reactions, all magnetic stirrers are driven by the high-speed rotation of the vertical magnetic line generating module in the vertical magnetic stirring and mixing platform 1 to rotate vertically with the horizontal line as the rotation axis, while ordinary magnetic stirrers rotate with the vertical line as the rotation axis, achieving the uniform stirring and mixing effect required for each reaction; the temperature, light, and current required for various types of chemical reactions are provided and executed by their respective functional modules. Moreover, the device of the present utility model can be integrated with an automated platform to realize automatic feeding, sampling, detection, and other automated operations for each reaction tube, achieving a truly fully automated high-throughput chemical reaction. Furthermore, due to the modular design based on the SLAS / SBS standard specifications, it is also very easy to achieve automated integration.
[0082] In this field, the implementation principles of all magnetic stirring devices are the same. They all form a changing magnetic field by rotating a driving magnet, and the stirring magnetic particle follows the magnetic field rotation under the action of the attractive force - repulsive force in the changing magnetic field, thereby realizing the stirring and mixing function. However, in this solution, the "vertical magnetic stirring and mixing technology" is adopted. The vertical magnetic line generating module generates a vertical magnetic field. When the driving module controls the vertical magnetic line generating module to rotate in the vertical direction, the magnetic field will rotate with the rotation of the vertical magnetic line generating module, and a driving field of vertical rotating magnetic lines can be formed outside the vertical magnetic line generating module. When the magnetic particle is located in this driving field, the magnetic particle will rotate with the rotation of the magnetic line, and the macroscopic manifestation of this process is that the magnetic particle rotates in the driving field in the same way as the vertical magnetic line generating module.
[0083] The present utility model adopts a unique "vertical magnetic stirring and mixing technology" as the basic platform of the reactor, combines precise temperature control technology (heating or refrigeration), light source power control technology, and direct / alternating current power supply control technology, and according to the modular design principle, based on the international laboratory automation SLAS / SBS standard specifications, on a platform device, "high-throughput temperature-controlled chemical reactions, high-throughput photochemical reactions, and high-throughput electrochemical reactions" can be carried out separately or in combination.
[0084] The high-throughput parallel chemical reaction device with modular design provided by the present utility model adopts modular design technology and fully complies with the international SLAS / SBS laboratory automation specifications and standards, and can conveniently and flexibly carry out high-throughput chemical experiments with free combinations of various reaction scales and various reaction types (temperature-controlled chemical reactions, photochemical reactions, electrochemical reactions).
