AI Technical Summary
Existing exosome extraction kits have difficulty effectively sealing reagent tubes, leading to leakage problems.
The reagent sealing mechanism utilizes a threaded drive shaft, a reagent storage base, and a reagent sealing plate to ensure that the reagent tubes are aligned with the sealing plate and inserted into the fixed mounting groove during storage, thus achieving a seal. Simultaneously, the locking mechanism prevents foreign objects from entering through the meshing of the active bevel gear and the locking plate.
It effectively prevents leakage of reagent tubes during storage and protects them from damage by foreign objects, ensuring the airtightness and safety of the reagent kit.
