Description

TECHNICAL FIELD

[0001] The utility model relates to experimental instrument equipment technical field especially, relates to a generator for reagent separation. BACKGROUND

[0002] Reagent separation refers to the process that a plurality of reagent components mixed together are separated and extracted one by one according to the difference of their physical and chemical properties by using specific technical means and process method.

[0003] Centrifugal reagent separation generator is an important tool for reagent separation. The centrifugal reagent separation generator uses the strong centrifugal force field generated by high-speed rotation to make different components in the mixed reagent produce different motion trajectories and settling velocities due to different centrifugal forces, thereby realizing separation.

[0004] The traditional centrifugal reagent separation generator has simple structure and convenient operation, and can well provide the function of reagent separation. However, the design of the centrifugal chamber and the rotor does not consider the convenient cleaning of residual reagent. The existence of many gaps, corners and hard-to-reach areas in the centrifugal chamber is easy to cause reagent residue. In addition, there is no special cleaning liquid delivery and waste liquid recovery system, and there is no preset pipeline for spraying cleaning liquid, so it is impossible to uniformly distribute the appropriate cleaning liquid to the surfaces of the chamber and the rotor for effective cleaning, thereby shortening the service life of the equipment. In addition, the residue of different batches or different types of reagents can also cause cross contamination, which seriously affects the accuracy and reliability of the subsequent separation results. At the same time, the traditional centrifugal reagent separation generator has limited temperature adjustment means and slow response speed. Usually, only simple heating or cooling elements such as simple heating wires or small fans are used, and there is no intelligent temperature control module, which seriously threatens the activity and structure of temperature-sensitive reagents, and finally causes the experimental or production reagent separation effect to have an unavoidable deviation. Therefore, a generator for reagent separation is proposed to solve the above problems. UTILITY MODEL CONTENT
