Dew prevention device for low-temperature microscope stage

Abstract

The invention relates to a low-temperature microscope, in particular to a dew prevention device for a low-temperature microscope stage, comprising a nitrogen bottle, a pressure reducing valve, a drying device, a flowmeter, a liquid nitrogen bottle, a temperature adjusting chamber, a low-temperature stage and a rewarming chamber, wherein the liquid nitrogen bottle is internally provided with a heat exchanger, the nitrogen bottle is connected with the liquid nitrogen bottle internally provided with the heat exchanger through an outlet pipeline, the pipeline is sequentially provided with the pressure reducing valve, the drying device and the flowmeter, the liquid nitrogen bottle internally provided with the heat exchanger is connected to a low-temperature chamber of the low-temperature stageof the inverted low-temperature microscope through a pipeline with the temperature adjusting chamber, the rewarming chamber is connected to a nitrogen outlet pipeline of the low-temperature stage, anobjective lens of the inverted low-temperature microscope is arranged below the low-temperature stage, and a spotlight is arranged on the low-temperature stage. The invention mainly solves the technical problem of easy dewing of a stage glass sheet of the low-temperature microscope stage in use, has the advantages of compact and small structure and convenience for use and can be configured both in a large laboratory and a small laboratory.

Description

technical field [0001] The invention relates to a cryogenic microscope, in particular to an anti-condensation device for a cryogenic microscope stage. Background technique [0002] Cryogenic microscopes are widely used in the field of low-temperature biomedicine, mainly to observe the changes of various cells and biological tissues through cryogenic microscopes in low-temperature environments. Now, people have directly observed the formation of ice crystals inside and outside the cells, the change of cell shape and size, etc. with a cryogenic microscope, and obtained a large amount of important information, so that they can qualitatively and quantitatively analyze and study the impact of low temperature on the test objects, which greatly promotes The development of the field of low temperature biomedicine, the achievement of these achievements has made people further realize the importance of low temperature microscopy. [0003] After decades of development, the low-tempera...
