Description

Technical Field

[0001] This novel experimental technology relates to inert gas and cryogenic protection technology and layered storage technology. In particular, it relates to a layered reagent storage tank with dual protection of inert gas and cryogenic temperature inside the tank, capable of monitoring temperature, humidity and oxygen concentration and providing alarm notification, and with freely adjustable layer height. Background Technology

[0002] Reagents, especially chemical reagents, often require inert gas storage to maintain their stability during storage, and some temperature-sensitive reagents also require cryogenic storage. According to patent searches, current laboratory storage methods for air- and temperature-sensitive reagents still rely heavily on empirical methods. For air-sensitive reagent bottles requiring inert gas storage, a better method is to store them in a glove box; a less desirable method is to directly seal any parts in direct contact with air using electrical tape. Samples are currently stored in vials or liquid chromatography vials, with a better method being to place them in a glove box, and a less desirable method being to place them in sample bags. NMR tubes are directly placed in plastic bags for rapid delivery. As for a scientifically sound method for cryogenic storage in the laboratory while maintaining an inert gas protective atmosphere, only a cryogenic glove box is available.

[0003] Layered storage technology with freely adjustable shelf height has only been reported in a very small number of patent searches. Publication number CN205333642U achieves free adjustment of sample drying pad height through X-hinged fixing. CN216753878U and CN209377044U achieve free adjustment of shoe rack and shelf shelf shelf height through sliding sleeve groove and nut adjustment of tightness and fixing. CN215225687U achieves free adjustment of shelf height by increasing the density of storage cabinet shelf grooves.

[0004] However, the above empirical methods have the following problems: Glove boxes are expensive and not all laboratories can afford them. Currently, the only workaround is to seal the parts in direct contact with air with electrical tape, place the sample in a sample bag, squeeze out the air, and then refrigerate it. However, this solution does not truly prevent air from affecting the reagents.

[0005] The X-hinged design does not allow for the free addition or reduction of partitions; it is only suitable for adjusting shelf height and therefore not for layered storage tanks. The sliding sleeve design relies heavily on the fit of the sleeve, groove, and adjusting nut, and is often designed for large structures such as cargo containers; it is not suitable for small structures like storage tanks. Utility Model Content

[0006] To meet laboratory needs, and for ease of use, simple structure, and low cost, this invention adopts an integral canister structure with internal slots for adjustable shelf height, layered storage, and dual protection against inert gas and low temperature. Due to its relatively simple structure, the canister is relatively inexpensive and convenient to manufacture.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A multifunctional reagent storage container capable of monitoring temperature, humidity and oxygen concentration, the storage container comprising a lid, a container body, a multifunctional square column, a partition and a cold source placement slot; The multifunctional square column is fixedly connected to the left and right sides of the inner wall of the tank. The top of the multifunctional square column is grooved near the tank opening to form a temperature and humidity monitoring and alarm module installation box or an oxygen concentration monitoring and alarm module installation box. Several layers of high-density partition left and right fixing grooves are evenly opened on the side of the multifunctional square column in the vertical direction. Several layers of partitions are movably connected in the several layers of partition left and right fixing grooves. The storage tank is equipped with a cold source placement slot at the bottom.

[0008] The compartment is equipped with storage cells, finger holes, Arabic numerals for cell positioning, and a passageway for the compartment. A cold source can be placed at the bottom of the storage tank, and the top cover of the storage tank is equipped with a three-way universal ground joint, a handle, and a can cover stopper.

[0009] The aforementioned storage tank has a cylindrical structure with a ground joint on its upper inner side for use with the tank lid stopper. The temperature and humidity monitoring and alarm module mounting box is used to house the temperature and humidity monitoring and alarm module, and the oxygen concentration monitoring and alarm module mounting box is used to house the oxygen concentration monitoring and alarm module.

[0010] The height and thickness of the left and right fixing slots of the partition are consistent, as is the distance between the left and right fixing slots of the two partitions. The partitions come in three sizes depending on their intended use: sample vial partitions, reagent vial partitions, and NMR tube partitions. The cold source includes dry ice, liquid nitrogen, and refrigerant in a refrigerator-freezing state. The storage tank lid consists of three parts: a universal ground joint for the tee, a lid handle, and a lid stopper. The universal ground joint for the tee is used to insert the tee to achieve vacuuming and inert gas replacement; the lid handle is used to lift the lid; and the lid stopper is used to engage with the ground joint of the lid on the tank body.

[0011] In the aforementioned storage containers, the left and right fixing slots of the sample vial compartment, NMR tube compartment, and reagent vial compartment are consistent with the left and right fixing slots of the compartment. There are two square, symmetrically arranged left and right fixing slots at both ends of the compartment. The finger-holding hole positions and sizes differ between the sample vial compartment, NMR tube compartment, and reagent vial compartment. The sample vial compartment and NMR tube compartment each have four finger-holding holes located diagonally above and closer to the inside of the left and right fixing slots, with each hole allowing one finger to pass through. The finger-holding hole of the reagent vial compartment is located at the very center of the compartment, and its opening size is large enough to accommodate four fingers from both hands. The storage cells of the sample vial compartment, NMR tube compartment, and reagent vial compartment are evenly distributed in a square arrangement at the center of the compartment. The size of the sample vial compartment storage cells can be further subdivided into several specifications according to the size of the sample vial. The NMR tube compartment storage cells can be further subdivided into several specifications according to the outer diameter of the NMR tube. The reagent vial compartment storage cells can be further subdivided into several specifications according to the size of the reagent vial.

[0012] The advantages of this invention are that the storage container is small in size, easy to transport, and suitable for laboratory use. All ground joint surfaces can be coated with silicone grease or petroleum jelly to enhance the overall sealing. The partitions are replaceable according to usage, allowing for the storage of various sizes of chemical reagent bottles, sample vials, and NMR tubes. The partitions can be freely layered and stored using the left and right fixing slots and the movable connection between the partitions. The partitions can be easily accessed and removed via the finger-holding holes. The storage compartments are square and evenly distributed in the center of the partitions, and the use of Arabic numerals for cell positioning facilitates the location and management of stored reagents. A notebook is also provided for recording specific reagent information. A cold source is placed at the bottom to maintain a low temperature inside the storage container. Temperature and humidity monitoring and alarm modules, as well as oxygen concentration monitoring and alarm modules, provide real-time monitoring of the container's interior and issue timely alarms when problems occur in temperature, humidity, or oxygen concentration.

[0014] The embodiments are described in detail below with reference to the accompanying drawings.

[0015] A multifunctional reagent storage container, the lid (2) is provided with a three-way universal ground joint (220), a handle (210) and a lid stopper (230). The storage tank body (1) is cylindrical, and there is a storage compartment inside the cylinder. The upper part of the inner wall has a grinding groove for use with the can lid grinding stopper (230). The storage tank body (1) is fixedly connected to the left and right sides of the inner wall. The top of the multifunctional square column is grooved near the can opening to form a temperature and humidity monitoring and alarm module placement box or an oxygen concentration monitoring and alarm module placement box (410). Several layers of high-density partition left and right fixing grooves (420) are evenly opened on the side of the column perpendicular to the square plane. Several layers of partitions (3) are movably connected in the several layers of partition left and right fixing grooves (420). The partitions are provided with storage cells (302), finger holes (303), Arabic numerals for storage cell positioning (304), and partition left and right fixing groove through grooves (301). A cold source can be placed at the bottom of the storage tank. The cold source includes dry ice, liquid nitrogen, and refrigerant stored in a refrigerator. The cold source can be used to cool the inside of the storage tank.

[0016] like Figure 3 As shown, the can lid (2) consists of three parts: a universal ground joint (220), a handle (210), and a can lid stopper (230). The universal ground joint (220) is used to insert the tee to achieve vacuum nitrogen replacement, the handle (210) is used to lift the can lid, and the can lid stopper (230) is used to fit the can lid stopper opening on the can body. All stopper openings can be coated with silicone grease or petroleum jelly to enhance the overall seal.

[0017] like Figure 7As shown, the temperature and humidity monitoring and alarm module mounting box or the oxygen concentration monitoring and alarm module mounting box (410) has two parts on the multifunctional square column (4) for mounting the temperature and humidity monitoring and alarm module (411) and the oxygen concentration monitoring and alarm module (413), respectively. A square ventilation window (412) is opened on the side of the mounting box for ventilation, so as to facilitate the monitor to monitor the relevant environmental data inside the tank. The height of the left and right fixing slots (420) of the partition is consistent with the thickness of the partition (3) and the distance between the two left and right fixing slots (420), and the length and width are consistent with the multifunctional square column (4). The temperature and humidity monitoring and alarm module can monitor the temperature and humidity inside the tank in real time. When the temperature or humidity exceeds a certain threshold, the alarm will sound. The oxygen concentration monitoring and alarm module can monitor the oxygen concentration inside the tank in real time. When the oxygen concentration exceeds a certain threshold, the alarm will sound. Through the temperature and humidity monitoring and alarm module and the oxygen concentration monitoring and alarm module, the user can control the temperature, humidity and oxygen concentration inside the tank within a certain threshold range. The temperature and humidity monitoring and alarm module and the oxygen concentration monitoring and alarm module in this utility model are both commercially available products. For example, commercially available temperature, humidity and oxygen concentration monitoring instruments with built-in alarm modules can monitor in real time via an APP or view the data in real time on a digital display screen. When the threshold is reached, the APP will send a text message or email reminder via the cloud. Alternatively, commercially available temperature and humidity instruments and humidity and oxygen integrated indicator cards can play a warning role by displaying temperature and humidity data digitally and changing the color of the indicator card.

[0018] like Figure 4 , Figure 5 and Figure 6 The partition (3) shown can be divided into sample bottle partition (310), reagent bottle partition (320) and NMR tube partition (330) according to its use. The left and right fixing slots (301) of the sample bottle partition, NMR tube partition and reagent bottle partition have two square left and right symmetrical slots at both ends of the partition (3), and the left and right fixing slots (301) and the left and right fixing slots (420) of the partition are consistent in size and shape.

[0019] The sample vial partition (310), NMR tube partition (330), and reagent vial partition (320) differ in the position and size of their finger-holding holes (303). The sample vial partition and NMR tube partition each have four finger-holding holes (303) located diagonally above and towards the inside of the left and right fixing slots (301) of the partition. Each finger-holding hole (303) allows one finger to pass through. The reagent vial partition's finger-holding hole (303) is located at the very center of its partition (320), and its opening size is large enough to accommodate four fingers from both hands. All finger-holding holes (303) are used for lifting or storing the partition (3). Simultaneously, all finger-holding holes (303) and the left and right fixing slots (301) of the partition allow for air circulation inside the container.

[0020] Several storage cells (302) for sample vial compartments, NMR tube compartments, and reagent vial compartments are evenly distributed in a square arrangement at the center of compartment (3). The sample vial compartment storage cells (302) can be further subdivided into several sizes according to the size of the sample vial. The NMR tube compartment storage cells (302) can be further subdivided into several sizes according to the outer diameter of the NMR tube. The reagent vial compartment storage cells (302) can be further subdivided into several sizes according to the size of the reagent vial. The compartment storage cells (302) can be conveniently located and managed by using Arabic numerals (304) for cell positioning. They can also be used with a notebook to record specific information about the stored reagents.

[0021] The layered storage of the partition (3) is mainly achieved through the cooperation of the partition (3) and the left and right fixing slots (420). When the partition (3) needs to be stored, the partition (3) is lifted through the finger hole (303). When the left and right fixing slots of the partition pass through the slot (301) and reach the position of the left and right fixing slots (420) at the appropriate height, the partition (3) is rotated 90 degrees so that the partition (3) is locked in the left and right fixing slots (420) to complete the storage of the partition (3). The layered storage of the partition (3) can be completed by repeating the above operation.
