Abstract
The utility model relates to a constant temperature metal bath heat cover which comprises a metal sheet, a heating element, a heat insulation pad and a pressure plate arranged subsequently from top to down; a temperature sensor is embedded in the metal sheet; the lead wires of the temperature sensor and the heating element are led out of the pressure plate. When being used in constant temperature metal bath, the constant temperature metal bath heat cover is covered on a test tube of a variable temperature metal module; when the metal bath works at the temperature between 0 DEG C and 100 DEG C, the heating element heats the constant temperature metal bath cover to 101 DEG C to 110 DEG C; at this time, the temperature on the top is higher than that at the bottom of the test tube, which can effectively prevent sample evaporation in the test tube.
Description
Technical field
The utility model relates to and is used for the thermostat metal bath heat lid that thermostat metal is bathed.
Background technology
Thermostat metal is bathed the instrument that provides the reactant reaction temperature, and be widely used in sample and preserve, the preservation of enzyme and reaction, and the degenerative treatments of nucleic acid and protein etc.
The main flow thermostat metal is bathed at present, comprise the alternating temperature metal module that inserts some test tubes of being close to device from top to bottom successively, semiconductor cooler and radiator, utilize the semiconductor cooler alternating temperature, the temperature follow procedure of alternating temperature metal module is heated up and cooling, be positioned over the invisible spectro reactant of metal module by temperature required variation thereby make.The metal bath lid that uses now is common module cage, and the metal bath operating temperature when the alternating temperature metal module adds to high temperature, because the test tube bottom temp is higher, makes that in vitro sample produces evaporation between 0～100 ℃, and most of sample is lost.
Summary of the invention
The purpose of this utility model provides a kind of being beneficial to and reduces the thermostat metal bath heat lid of sample evaporation amount in vitro.
Thermostat metal of the present utility model is bathed the heat lid and is comprised from bottom to top metallic plate, heater element, heat insulating mattress and the pressing plate of device successively, is embedded with temperature sensor in the metallic plate, and the lead-in wire of temperature sensor and heater element is drawn outside the pressing plate respectively.
Above-mentioned heater element can be heating film or ptc heating sheet.
Thermostat metal is bathed heat cover on test tube, during the work of alternating temperature metal module, utilize heater element that thermostat metal is bathed lid and be heated to 101～110 ℃, this moment, the test tube head temperature was higher than the test tube bottom temp, can effectively suppress sample evaporation in vitro.
It is easy for installation that thermostat metal of the present utility model is bathed the heat lid, is fit to large-scale production, and thermostat metal is bathed and used this heat lid, can effectively suppress sample evaporation in vitro.
Description of drawings
Fig. 1 is that thermostat metal is bathed heat lid schematic diagram;
Fig. 2 is that thermostat metal is bathed heat lid application schematic diagram, among the figure: 1-metallic plate, 2-temperature sensor, 3-heater element, 4-pressing plate, 5-heat insulating mattress, 6-looper plug; The 7-test tube, 8-sample to be checked, 9-alternating temperature metal module, 10-semiconductor cooler, 11-radiating element, 12-heat transfer medium.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1, thermostat metal of the present utility model is bathed the heat lid, comprises metallic plate 1, and heater element 3 is arranged on metallic plate from bottom to top successively, heat insulating mattress 5 and pressing plate 4, in this example, metallic plate is an aluminium sheet, and heater element adopts heating film, heating film and heat insulating mattress are fastened on the aluminium sheet by pressing plate, dug groove in aluminium sheet, be equipped with temperature sensor 2 in the groove, the lead-in wire of temperature sensor 2 and heater element 3 is drawn respectively outside the pressing plate 4.In the legend, looper plug 6 is arranged in the lead-out wire termination of temperature sensor 2.
Fig. 2 is that thermostat metal is bathed heat lid application schematic diagram, thermostat metal is bathed heat and is covered on the test tube of alternating temperature metal module, utilize looper plug test thermostat metal to bathe the temperature of heat lid, and then the caloric value of regulating heating film, the aluminium sheet temperature that makes thermostat metal bathe the heat lid is controlled at 101～110 ℃, thereby keep the test tube head temperature to be higher than the test tube bottom temp, effectively suppress sample evaporation in vitro.
