Multifunction organization embedding and refrigerating plant

Abstract

This invention is a tissue embed-freeze apparatus for frozen tissue section used for life science experiment and medical pathological tissue examination, comprised of a multifunctional liquid nitrogen storage thermostatic bottle and an adjustable suspending water tank. The multifunctional liquid nitrogen storage thermostatic bottle is internally designed with a conical baffle for the adjustable suspending water tank to enter, used for freezing the embedded tissue and reducing volatilization of liquid nitrogen therein. The adjustable suspending water tank is disposed with two freely operable pull rods on two sides thereof, in order to adjust immerging depth and position of the water tank into the liquid nitrogen in the thermostatic bottle within 0 to 30cm according to actual need. With utilization, this invention can rapidly and conveniently carry out high quality freezing process can be carried out on embedded tissue and embryo as a special tissue embed-freeze apparatus, especially suitable for life science, pathology and anatomy, etc., which simultaneously bring new improvement for existing tissue embed-freeze module.

Description

technical field [0001] The invention is an apparatus for life science experiment and medical pathological histology examination, specifically a device for embedding tissue and embryo liquid nitrogen freezing during the frozen section experiment. Background technique [0002] The production of frozen sections is an important part of immunohistochemical techniques and in situ hybridization histochemical techniques. By using labeled specific antibodies (or specially labeled nucleic acid probes) to accurately locate and characterize antigens (or functional genes) in tissues , Quantify and determine tissue-specific expression assays at different developmental stages. The tissue embedding freezing device is an indispensable routine tool for tissue cryosectioning in the study of life histology and pathology, and it is also an important step in the process of preparing tissue and embryo sections. Since there is no specialized tissue embedding freezing device, it greatly increases t...

Problems solved by technology

However, since there is no specialized tissue embedding freezing device at present, it is necessary to hold a container containing isopropanol in one hand, and use tweezers in the other hand to pick up the embedding cassette and immerse it in isopropanol, which increases the manual operation process. Due to the large opening of the liquid nitrogen bottle, the liquid nitrogen volatilizes too much, and the liquid nitrogen needs to be added again during the operation, which causes waste of liquid nitrogen on the other hand.

Therefore, the traditional tissue embedding process is cumbersome, time-consuming and labor-intensive, which affects work efficiency, and it is very necessary to improve it.
