Full-automatic multi-step freezing instrument

Abstract

The invention discloses a full-automatic multi-step freezing instrument and belongs to the field of biotechnology. The full-automatic multi-step freezing instrument comprises a box body, a box cover and a power device, wherein the interior of the box body is of a cavity lidless structure; an ejection inclined block is arranged at the bottom of the box body; a main rod guide hole and a bracket are arranged on the box cover; the power device and a temperature control device are mounted on the freezing instrument. In order to solve the problems that all samples in a freezing room are only frozen by the same freezing steps in the process of freezing and preserving device cells, either the device is imported or the manual operation is required, the device is high in subjectivity, low in accuracy, high in labor cost, complex in device container structure, the samples are inconveniently taken, the instrument is inconveniently cleaned, and the next test can be carried out by taking the samples after the test is completed, the invention provides a cell freezing device which has the advantages that the freezing rate reaches -70 DEG C per minute or is even greater than -70 DEG C per minute; the same batch of samples in the freezing room has a plurality of freezing rates; the cell freezing device is fully-automatic, can be automatically developed and produced, and is low in cost and simple in container structure; the samples can be conveniently taken out; the instrument can be conveniently cleaned; the samples can be uniformly taken out after a plurality of tests.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a cell sample freezing device, in particular to a fully automatic multi-step program freezing device. Background technique [0002] Since the end of the 20th century, developed countries have stepped up their competition for biological species resources, and this field has become a battlefield without gunpowder. Establishing a biological cell resource bank to preserve biological cells (currently mostly sperm cells, embryos or egg cells) can restore living animals after many years, which is of great significance to the fields of species resource preservation, breeding and reproduction. [0003] Existing freezers are divided into two types according to the degree of automation, one is fully automatic, and the other is manual. Fully automatic, relying on imports, with a set of procedures for samples in the freezer, all samples can only get the same effect, and the cooling rate of the por...

AI Technical Summary

Problems solved by technology

[0020] The purpose of the present invention is to provide a fully automatic multi-step program freezer to solve the problem that in the process of cell cryopreservation in existing equipment, all samples in the freezer can only perform the same set of freeze programs, which either rely on imports or require manual operation. Strong reliability, low precision, high labor cost, complex structure of equipment and containers, which is not conducive to sampling and cleaning instruments, and the next test can only be performed after the test is completed. Provide a freezing rate that reaches or exceeds -70°C / min. There are multiple sets of freezing rates for the same batch of samples in the chamber, high precision, fully automatic, independent research and development and production, low cost, simple container structure, easy to take out samples, clean the instrument, and a cell freezing device that can take out samples uniformly after multiple tests
