Ice bath sample rack device for homogenizing and homogenizing platform thereof

Abstract

The invention provides an ice bath sample rack device for homogenization and a homogenization platform thereof, the ice bath sample rack device comprises an ice bath box, a pipe rack, a sample pipe and a waste liquid receiving disc, the pipe rack is connected with the waste liquid receiving disc through a quick release structure; the waste liquid receiving disc can prevent cross contamination caused by liquid drops dropped by a homogenizing tool bit, and the waste liquid receiving disc can extrude the sample pipe, so that the sample pipe is prevented from moving along with the up-down movement of the homogenizing tool bit, and the problem of non-uniform sample homogenization is solved.

Description

technical field [0001] The invention relates to an experiment in the field of biochemistry, an automatic analysis instrument and an automatic sample pretreatment device, in particular to an ice-bath sample rack device for homogenization with clamping sample tubes and receiving waste liquid. Background technique [0002] In chemical analysis testing experiments, the homogenization process of solid samples is the most widely used experimental process. There are three conventional methods of homogenization: the first is the ceramic ball mill crushing method, which uses high-speed vibrating ceramics to collide violently with the sample to break and homogenize the sample. The second is the slapping homogenization method, which has special instruments and products, and is suitable for homogenization of larger samples. The third is the high-speed rotating stainless steel head homogenization method, which is suitable for the homogeneous extraction experiment operation of solid and ...

Problems solved by technology

[0003] First, the traditional device for automatic continuous homogenization of multiple samples, when there is no waste liquid receiving tray, the problem of cross-contamination between sample tubes caused by dripping during the movement of the homogenizer head

When there is a waste liquid receiving tray that moves with the cutter head, although it can receive the dripping waste liquid, there are problems such as the waste liquid receiving tray is small in size, difficult to disassemble and inconvenient to clean.

Therefore, the volume capacity and quick disassembly and cleaning of the waste liquid receiving tray have become a pain point in demand

[0004] Second, in the traditional device for automatic continuous homogenization of multiple samples, when the sample tube is not fixed, the unfixed sample tube will move up and down with the homogenizer head due to the viscous suction between the high-speed cutter head and the sample, resulting in homogenization of the samples. The quality knife head can only work at a certain height of the sample tube

[0005] Third, the traditional automatic continuous homogenization device for multiple samples, the high temperature generated by the high-speed shearing of the sample by the homogenizer head during the homogenization process, causes the volatilization loss of the target compound in the sample and the target compound after the volatilization loss of the extraction reagent Concentration change problem
