-70 ℃ ultra-low temperature ghd outlet are widely used in molecular cloning experiments stored in E. coli, competent cells and into the phage of the original species. At present, cryopreservation technology development is more mature, which Haixin encyclical, especially above -86 ° C ultra-low temperature GHD on behalf of. This ultra-low temperature GHD generally have relatively complete operation of the equipment to ensure functionality.
For example, high temperature alarm function, power outages, filter blockage detection function and automatic input subsidies, sample security alarm systems, micro-processing and analog control systems, CO2 backup system and recorder system. Generally examine the performance of ultra-low temperature ghd hair straightener from the lowest refrigeration temperature, volume size, shape characteristics ( horizontal or vertical ), compressor noise, size, vibration amplitude, the temperature uniformity of the cabinets, the failure rate (especially the compressor) the spatial arrangement of cloth and other optional types with their own requirements and laboratory situation fully into account.
Mainly concerned about the future the ghd reliability of ultra-low temperature and able to meet the different sample storage conditions, including temperature and gas composition. In addition, some companies in order to meet the high requirements of biological material on the temperature uniformity, in GHD shelf, for cooling the metal ring or shelf design for the hole -shaped, to solve the heat problem, improve the freezing rates and increase the consistency of the temperature sex.
