Advantages
Patent technology: High temperature control accuracy: adopting high-precision temperature control instrument, automatic PID adjustment, automatic constant temperature; high-performance platinum resistance PT100 sensor, It is placed in the middle of the sample group to ensure that the measured temperature is highly consistent with the temperature of the samples on both sides, which meets the requirements of the latest standards. stainless steel probe, stable performance and high precision. It adopts fully enclosed, low noise, long life magnetic induction stirring motor which can work normally in the environment with low temperature and high humidity. The medium in the tank is forcibly agitated and the medium has good fluidity, and high quality stainless steel heater etc. The equipment has small temperature fluctuations and good uniformity.
A large number of samples are placed, equipped with a stainless steel sample basket, which can freeze 60 standard 10*10*55mm samples at a time, and other small samples can be frozen more. The position of the sample basket in the freezing tank meets the requirements of the new standard that the distance between the sample and the cold tank wall is greater than 10mm, and the height of the sample immersed in the freezing medium is greater than 25mm, and the automatic lifting function of the sample basket is set, which can be stopped at any position within the allowable range, which greatly facilitates the clamping of samples.
