AI Technical Summary
There is a lack of economical and effective protection for storing air-sensitive and temperature-sensitive reagents in existing laboratories. Glove boxes are expensive, electrical tape sealing cannot completely isolate the effects of air, and low-temperature storage methods are not scientific enough.
A layerable inert gas cryogenic dual-protection storage tank has been designed. It adopts an integral tank structure, with fixed buckles and removable partitions on the inner wall. It is equipped with a cold source and a universal three-way stopper, supporting layered storage and cryogenic protection.
It enables the economical provision of inert gas and cryogenic protection in the laboratory, facilitates the storage and management of reagent bottles and NMR tubes of different sizes, enhances sealing, and is suitable for the layered storage of various reagents.

Abstract
Claims
1. A storage tank with stratified access and cryogenic dual protection by inert gas, characterized in that: The storage tank includes a tank body (200), and the inner wall of the tank body is uniformly fixed with several layers of fixing buckles (400). The tank body is also equipped with several layers of removable storage compartments (300). The middle area of the surface of the access compartment is provided with a storage cell, a finger hole and Arabic numeral markings for positioning, and a fixing slot that mates with the fixing buckle (400) and a buckle passage slot that allows the fixing buckle to pass through are provided around the perimeter; The bottom of the storage tank is provided with a cold source placement slot (500). The top of the storage tank is equipped with a lid, and the top of the lid (100) is provided with a three-way universal ground joint (102) and a handle (101), and the lid is surrounded by a lid stopper (103).
2. The storage tank of claim 1, wherein: The access compartment is a sample vial access compartment (310), a reagent vial access compartment (320), or an NMR tube access compartment (330). The fixing buckle (400) is composed of a buckle assembly (401) and a buckle base assembly (402); The card holder assembly (402) is fixed on the inner wall of the storage tank body (200), and the buckle assembly (401) is a cylinder disposed on the top surface of the card holder assembly (402).
3. The storage tank of claim 2, wherein: The reagent bottle access compartment (320) has a left and right fixing buckle through groove (321), a reagent bottle access compartment finger holding hole (322), a reagent bottle access compartment storage cell (323), a left and right fixing buckle groove (325), and Arabic numerals (324) for positioning the reagent bottle access compartment storage cell; the NMR tube access compartment (330) has a left and right fixing buckle through groove (331), an NMR tube access compartment finger holding hole (332), an NMR tube access compartment storage cell (333), a left and right fixing buckle groove (335), and Arabic numerals (334) for positioning the NMR tube access compartment storage cell.
4. The storage tank of claim 3, wherein: The sample vial access compartment (310) and the NMR tube access compartment (330) each have four finger-holding holes located at the upper and lower ends of the two left and right fixed buckle passage slots and close to the inside. Each finger-holding hole can allow one finger to pass through. The finger-holding hole of the reagent vial access compartment is located at the center of the sample vial access compartment. The size of the finger-holding hole opening can accommodate a total of four fingers of both hands to pass through. The left and right fixing buckles of the sample bottle access partition (310), the NMR tube access partition (330), and the reagent bottle access partition (320) have the same shape as the left and right fixing buckle grooves.
