[0002] EP tube racks are commonly used in biological laboratories, used to store EP tubes needed during experiments. During experiments, it is often necessary to label EP tubes, cap each tube individually, and shake and mix them.

[0003] EP tube racks can be divided into different specifications according to the size of EP tubes. However, the sizes of EP tubes prepared by different manufacturers may vary slightly. On the one hand, EP tubes placed on the tube rack often shake and change directions, which is not conducive to sample addition and labeling in daily work. On the other hand, in daily experiments, an appropriate number of EP tubes are taken out according to the number of samples or prepared reagents and placed in the tube rack for operation. However, when processing samples in large quantities, it is necessary to add samples or reagents to each EP tube and then cover them one by one. In daily experimental operations, it is often necessary to mix the components in the EP tube by shaking. Therefore, the EP tube with the reagent added needs to be removed from the tube rack, mixed with a shaker, and then the EP tube is put back for subsequent experiments. When the number of samples is large, it takes a lot of time and seriously reduces work efficiency. Utility Model Content

[0028] The present application provides a multifunctional EP pipe rack capable of oscillation and selective low temperature. Figure 1 、 Figure 2, including an outer shell 100 and a base 200. Specifically, the outer shell 100 is a box-shaped structure with an open top. The EP pipe rack 300 is arranged in the outer shell 100. The EP pipe rack 300 is distributed with an array of EP pipe accommodating holes 310 for holding EP pipes 320. The outer shell 100 is connected to the base 200 through a plurality of elastic connectors 400, and the base 200 is provided with a driver for pushing the outer shell 100 to drive the EP pipe rack 300 to vibrate and oscillate the EP pipe.

[0029] For example, see again Figure 1 The EP tube rack 300 provided in this application contains 96 holes, which can be used to place 1.5mL EP tubes. Of course, it can also be adapted to other specifications, sizes or quantities.

[0030] Routine experiments using EP tubes often require mixing the contents of the tubes by oscillation. The multifunctional EP tube rack provided by this application incorporates an electric oscillation mixing mechanism, eliminating the tedious steps of removing the reagent-filled EP tubes from the rack, mixing them with an oscillator, and then returning them for subsequent experiments. This eliminates the time-consuming and significantly reduced work efficiency associated with large numbers of samples. The multifunctional EP tube rack provided by this application achieves instant mixing after sample addition by energizing the driver, eliminating the need for removal and replacement, significantly improving work efficiency.

[0031] The driver is arranged at the center between the outer shell 100 and the base 200 ( Figure 1 (not shown), the driver is an electric driver connected to the power supply via a cable; illustratively, the driver uses a conventional electric device such as an electric push rod, a linear motor, a vibration generator, etc. Exemplarily, the elastic connector 400 is an elastic metal connector, such as a spring. Furthermore, a power switch and a gear button for controlling the driver are provided on the base to facilitate manual control of the oscillation and mixing by the experimenter.

[0032] In a further embodiment, biological experiments often require sample processing in a low-temperature environment (such as RNA extraction, protein extraction, flow sorting, live cell processing, etc.). However, ordinary EP tube racks used in daily life cannot provide a low-temperature environment. The multifunctional EP tube rack provided in the present application has a receiving cavity 110 for accommodating a cold storage medium in the outer shell 100. The receiving cavity 110 is adjacent to and covers the entire EP tube rack 300. In an optional embodiment, a non-fixed connection is adopted between the EP pipe rack 300 and the outer shell 100. The EP pipe rack 300 is limited in the outer shell 100 by setting a soft cushion layer in the gap, or the EP pipe rack 300 is directly placed in the outer shell 100. At this time, the accommodating chamber 110 can be set below the EP pipe rack 300. By first removing the EP pipe rack 300, the cold storage medium 111 located in the accommodating chamber 110 can be loaded, removed or replaced. Exemplary: the cold storage medium 111 can use polyurethane permanent white sponge as the main material, of course, other cold storage materials can also be used. Polyurethane permanent white sponge has the property of maintaining elasticity after low-temperature freezing. When a low-temperature environment is required for experiments, the cold storage medium 111 is taken out of the pipe rack in advance, added with water and frozen, and then put back into the pipe rack to provide the low-temperature environment required for the experiment. When a low-temperature environment is not required, the polyurethane permanent white sponge pad under the EP pipe rack 300 can serve as a buffer device, thereby providing a buffering effect to prevent certain fragile components from being damaged due to excessive vibration. In another optional embodiment, the outer shell 100 may be provided with an opening on the side for taking out or loading the cold storage medium. In this case, the EP pipe rack 300 needs to be fixed relative to the outer shell 100. The relative fixing method can adopt a soft connection or a hard connection.

[0033] In a further embodiment, see again Figure 2 The EP tube receiving hole 310 is provided with an elastic sheet 330 for securing the EP tube 320. By inserting the EP tube 320 into the EP tube receiving hole 310 and squeezing the elastic sheet 330, the EP tube 320 remains stable within the EP tube receiving hole 310. Specifically, the elastic sheets 330 are provided on opposite sides of the EP tube receiving hole 310 and protrude toward the center. Exemplarily, the elastic sheets 330 are made of an elastic material such as elastic metal, elastic plastic, or rubber to facilitate insertion and removal of the EP tube.

[0034] In a further embodiment, see Figure 1 and Figure 3On the EP tube rack 300, position-limiting brackets 340 are positioned in the same direction relative to all EP tube receiving holes 310 to support the EP tube caps. In an experimental scenario, for example, position-limiting brackets 340 are positioned behind the EP tube receiving holes 310. When an EP tube 320 inserted into the EP tube receiving hole 310 opens the EP tube cap backward, the EP tube cap is supported by the position-limiting brackets 340, limiting the opening angle of the EP tube cap beyond 90 degrees. For example, position-limiting brackets 340 are U-shaped. After the EP tube 320 is placed, the U-shaped brackets engage the connection between the EP tube body and the cap, ensuring that the EP tubes 320 are fixed to the EP tube rack 300 in the same direction, facilitating subsequent sample loading and labeling, while also ensuring that all tube caps open in the same direction.

[0035] For further information, see Figure 1 and Figure 4 The outer shell 100 is connected to the upper cover 120. The upper cover 120 and the EP tube cover have the same opening and closing direction, both opening backwards. A columnar protrusion 121 corresponding to each EP tube receiving hole is provided on the inner side of the upper cover 120 facing the EP tube receiving hole. Figure 5 When closing the upper cover 120, the cylindrical protrusions 121 are used to push the EP tube caps, thereby capping the EP tubes in batches. However, when processing samples in large batches, it is necessary to cap each EP tube one by one after adding the sample or reagent. This wastes time and reduces work efficiency. The multifunctional EP tube rack provided in the embodiment of the present application is provided with an upper cover 120. The cylindrical protrusions on the inner surface of the upper cover 120 correspond to the hole positions one by one. When the EP tubes containing samples or reagents are fixed in the tube rack in the same direction, closing the upper cover 120 can achieve batch capping, greatly saving work time and effectively improving work efficiency.

[0036] It should be further explained that when the upper cover 120 is used for batch capping, when the opening direction of the EP tubes is uniform and the opening angle does not exceed 90 degrees, usually no abnormality will occur. The multifunctional EP tube rack provided by the present application ensures that the opening direction of the EP tubes is uniform and the opening angle does not exceed 90 degrees through the limiting bracket 340. However, in a few cases, the problem of deviation in the opening direction of the EP tubes may cause abnormalities in batch capping. In order to further solve this abnormality, the multifunctional EP tube rack provided by the present application is also provided with a movable scraper. In an optional embodiment, the scraper is an independent component, and the experimenter holds the scraper from back to front before closing the cover to scrape all the EP tube covers so that their opening angles are much less than 90 degrees. In another optional embodiment, see Figure 1 and Figure 6The EP tube rack 300 has a pair of slide rails 350 on the left and right sides. The direction of the slide rails 350 is consistent with the opening and closing direction of the EP tube cover. A slider 351 is provided on the slide rail 350. The slider 351 is set as a magnetic slider. The two ends of the scraper 360 are set as magnetic ends. The two ends of the scraper 360 are magnetically connected to the sliders on both sides. Before closing the cover, the experimenter manually controls the scraper 360 to move from back to front once along the slide rail 350. Figure 7 During the movement, the opening and closing angles of all EP tube caps are adjusted to be much less than 90 degrees. After the movement is completed, the scraper 360 can be removed and stored in the storage cavity provided on the outside of the outer shell 100 for next use. When the opening and closing angles of all EP tube caps are adjusted to be much less than 90 degrees, the upper cover 120 can be used to cap the tubes in batches.

[0037] Based on the multifunctional EP tube rack provided above, it can be found that the present application provides a multifunctional EP tube rack that integrates EP tube fixing, batch capping, low-temperature buffering, and oscillation mixing. The uses of the multifunctional EP tube rack provided in the present application can be divided into four parts: (a) EP tube fixing, an elastic sheet is provided in each hole at the bottom of the tube rack for fixing the EP tube, and a U-shaped bracket is provided behind each hole for placing the connection between the EP tube body and the lid, fixing the direction of the EP tube, and facilitating sample addition, labeling and subsequent batch capping; (b) batch capping, the lid part of the device is provided with a columnar protrusion structure corresponding to the tube holes one by one. When the lid is closed, the EP tubes fixed on the tube rack and in the same direction can be capped in batches, which can effectively save time and improve work efficiency; (c) low-temperature buffering, the bottom of the EP tube rack is a replaceable polyurethane permanent white sponge, which has the characteristic of maintaining elasticity after low-temperature freezing. It can provide a buffering effect at room temperature and provide a low-temperature environment by being immersed in water and frozen; (d) oscillation and mixing, the bottom of the multifunctional tube rack is an electric oscillation and mixing device with a spring as the main structure. After power is turned on, the sample is oscillated and mixed by the shaking of the spring.

[0038] During use, place the desired EP tubes on the tube rack. The springs in the holes secure the tubes. Open the tubes, and the U-shaped bracket at the rear fits snugly into the connection between the tube body and the lid, preventing the tubes from rotating and ensuring consistent orientation. Then, add the sample as needed for your experiment. When you're finished, close the lid. The cylindrical projections on the lid, corresponding to the holes, will secure the tubes in batches. The lid can then be labeled. If a low-temperature environment is required for your experiment, remove the sponge from the bottom of the rack, soak it in water, and freeze it before reinstalling it. Since the sponge retains its elasticity after freezing, it not only provides a low-temperature environment but also acts as a buffer. To oscillate and mix the liquid components in the EP tubes, connect the power supply below, turn on the switch, adjust it to the appropriate setting, and oscillate to mix the sample. There's no need to remove and replace the EP tubes throughout the experiment, making it convenient, time-saving, and significantly improving work efficiency.

[0039] The above description is only a preferred embodiment of the present application and does not limit the present application in any form or substance. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present application, and these improvements and supplements should also be regarded as the scope of protection of the present application. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the content and scope of the present application, which are all equivalent embodiments of the present application; at the same time, any equivalent changes, modifications and evolutions made to the above-mentioned embodiments based on the essential technology of the present application are still within the scope of the technical solution of the present application.
