DLSB Series Low-temperature Cooling Liquid Circulating Pump
Brief Introduction:
Adoption of low-temperature liquid circulation equipment of compression refrigeration methods can cool the tube, the reaction bottles directly and so on to have chemical reaction under low-temperature and store chemical and biological products under low-temperature。Besides, it can also be combined with Rotary Evaporator, Glass reactor, Multi-purpose Circulating Water Vacuum Pump.
Main features:
●Large-capacity open bath combined with outside loop can not only be used as freezing tanks, but also provide cooling fluid outside.
●Digital setting and display of temperature, easy to operate.
● Refrigeration compressors and other key parts adopt products with famous brands of the United States, Germany, and France and have high reliability and efficiency.
●Circulating system adapts SUS304, 316 and macromole anti corrosion substance, which can prevent rust, corrosion, and low temperature liquid pollution.
