Aluminum block low-temperature constant temperature bath PSL-2500

Unlike traditional liquid as a thermal medium, aluminum block refrigeration is used to avoid the shortcomings of liquid medium flammability and moisture absorption, making the testing process safer and cleaner. The minimum sample temperature is -80 ℃. Can be used: maximum 1L sample bottle (PSL-2500B type), test tube, and centrifuge tube. ■ Equipped with a strong magnetic stirrer as standard. In order to avoid damaging the atmosphere and the greenhouse effect on Earth, a helium cooling system is used. Due to its compact design, the use and placement of the instrument (in a ventilated kitchen or laboratory bench) are very convenient. The operation panel can rotate, making it easy to operate whether the host is placed horizontally or vertically. The PSL-2500B model can measure and control the sample temperature by selecting a sample temperature sensor or a PTFE temperature sensor. (PSL-2500A type, can only measure the temperature of the sample and cannot be controlled) ■ PSL-2500B type, can use aluminum block refrigeration or replace it with aluminum slot refrigeration. When cooling the aluminum slot, aluminum particles (optional) are placed into the aluminum slot, so that containers of different shapes can be inserted into the aluminum particles for cooling and cooling
