A laboratory chemical reagent auxiliary agent storage device, including box, still include: rotation axis, through bearing rotation connection on the inner wall of box, the placement board with cavity structure is fixedly installed on the surface of rotation axis in equal interval, wherein, the placement board is equipped with the limiting ring corresponding with the placement groove, the upper portion of placement board is equipped with, the utility model discloses the placement groove and limiting ring can be classified and placed to the reagent bottle of storage, and simultaneously in the placement operation, through extruding piece manual extrusion operation inflation, change the size of placement groove and limiting ring, thereby better adaptation the size of the reagent bottle of placement, practical high flexibility, and give the reagent bottle outside placed with good protection effect, avoid the device to shake and knock damage in the transportation process and take place.

This invention relates to the field of chemical control technology and discloses a method and system for risk assessment of the entire life cycle of laboratory chemicals. Through storage incompatibility analysis, this invention achieves accurate identification, classification, isolation, and control of risks associated with incompatible storage. It also quantifies and records the degradation process of chemicals accumulated during long-term storage through environmental stress degradation analysis, providing a realistic degradation baseline for subsequent stages. By extracting key feature information from experimental record data and dynamic parameters, the impact of the experimental process on the subsequent stability of waste is transformed into structured data. Finally, the final test data, hazardous characteristic time-series data, and process influencing factor set are integrated to conduct risk evolution simulation, enabling forward-looking prediction of risk evolution trends during waste storage. This invention, through the quantitative transmission and integration of risk information throughout the entire life cycle, solves the problem of inaccurate risk assessments caused by independent assessments and fragmented information in traditional methods.
