Abstract

The invention discloses a laboratory thermostat, which comprises an equipment shell and a group of cushion frames installed at the bottom of the equipment shell; a touch panel is installed on the front side surface of the equipment shell in an embedded manner, a heater is installed at the inner bottom of the equipment shell, two temperature sensors are symmetrically arranged on two opposite inner side walls in the equipment shell, the equipment shell is internally filled with a heating medium, a bottomless containing groove is fixedly inserted in the top of the equipment shell, a placement frame is installed above the bottomless containing groove, and a plurality of placement holes are formed in the placement frame in an array mode. On one hand, an old filling heating medium after impurities are filtered out can be pumped back into the equipment shell again to be reused, so that the heating medium can always keep good heat conduction efficiency; and on the other hand, the stability performance of the placement frame after the placement frame is fed into the bottomless containing groove is greatly improved in a manual mode, so that accidents such as disintegration of the placement frame and the test tube in the heating process are avoided.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a laboratory thermostat. Background technique [0002] The thermostatted autosampler is equipped with a cooling / heating module, using Peltier elements for effective cooling of the air. When switched on, the front side of the heating / cooling Peltier element is set according to the temperature. A fan draws air from the sample tray area and passes it through the channels of the heating / cooling module. Fan speed is determined by environmental conditions. In the heating / cooling module, the air reaches the temperature of the Peltier elements, these thermostats are then blown under the special sample pan, where it is evenly distributed and flows back into the sample pan area. From there the air enters the thermostat. This circulation mode ensures efficient cooling / heating of the vials. In cooling mode, the other side of the Peltier element becomes so hot that it must be c...
