Description
Technical field
The utility model relates to the low temperature research equipment of biomaterial, particularly a kind of cryomicroscope objective table.
Background technology
Cryomicroscope can be studied biomaterial generating process at low temperatures dynamically, intuitively on microscopic dimensions, the low temperature objective table is the core component of cryomicroscope.Along with the reduction of environment temperature in biological sample and the objective table in the low temperature objective table, the easy dewfall of the outside surface of objective table sight glass, frosting have hindered light and have normally passed through sight glass.To be difficult to the situation of change by microscopic examination biological sample in the objective table this moment.
At present, the sight glass of some cryomicroscope objective tables has used double layer glass, and this structure helps thermal insulation, has reduced the possibility of sight glass outside surface dewfall, frosting.If but the temperature-fall period last very long of biological sample, the cold in the low temperature objective table still can transmit out, causes the temperature of sight glass to reduce sight glass outside surface dewfall, frosting.The cryomicroscope that some are also arranged is with an outer cover in order to prevent the generation of translucent element dewfall such as objective table sight glass in the course of work, frosting phenomenon outside microscope, dashing in outer cover has the inert gas of enough keeping malleation.Though this structure can prevent dewfall, frosting phenomenon, it is very inconvenient to make that cryomicroscope installs sample additional, if the microscope of cryo-microscope system is used for other purposes, also must remove anti-condensation, frosting overcoat on the microscope.
Summary of the invention
The utility model is at the problem of the easy frosting of present cryomicroscope objective table, dewfall, has proposed a kind of cryomicroscope objective table, and low temperature uses for a long time, not dewfall, frost-free.
The technical solution of the utility model is: a kind of cryomicroscope objective table, comprise the samming heating chamber, electric heater, the sample refrigerating chamber, the electrical heating ring, sight glass, the heat-barrier material shell, control system, cryomicroscope objective table whole casing is made of heat-barrier material, be divided into samming heating chamber and sample refrigerating chamber about the cryomicroscope objective table, there is a nitrogen inlet on the samming heating chamber left side, there is electrical heating inside, samming heating chamber the right exports to the sample refrigerating chamber, the sample refrigerating chamber a sight glass respectively arranged up and down, sight glass is positioned in the middle of the electrical heating ring, between the right of sight glass and the heat-barrier material shell flow-guiding mouth is arranged, control system output control electric heater and electrical heating ring.
Described control system comprises controlling thermocouple, thermopair, the temperature adjustment current driver, current driver, data acquisition module, the temperature adjustment D/A converter, D/A converter, microcomputer, the temperature signal that controlling thermocouple in the sample refrigerating chamber records is through data acquisition module input microcomputer, microcomputer is to the temperature signal that receives and after handling, the output control signal, through the temperature adjustment D/A converter, the temperature adjustment current driver is controlled electric heater, near the outer flow-guiding mouth of electrical heating ring thermopair records temperature signal through data acquisition module input microcomputer, after microcomputer is judged, export another road control signal, through D/A converter, current driver is controlled the electrical heating ring.
Described samming heating chamber and sample refrigerating chamber are also separated by heat-barrier material, and described sight glass is made by double layer glass.
The beneficial effects of the utility model are: the utility model cryomicroscope objective table, have anti-condensation and frosting function, and can work for a long time at low temperatures; Indoor temperature branch is even, the temperature-controlled precision height; Total is simple, device is small and exquisite, easy to operate.
