DESCRIPTION
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, Vacuum Freeze-drying Box, Muti-purpose Circulating Water Vacuum Pump.
FEATURES
1. Air- cooled(import) closed compressor, quality and reliable.
2. Are of high quality refrigeration unit dedicated relay, protector, capacitors and other devices, quality assurance.
3. Digital temperature display, microcomputer control, operation is simple.
4. Cooling capacity, cooling speed, which greatly improved work efficiency.
5. With normal use of water scarcity, water quality, water pressure, poor water temperature and high temperature working conditions, which can effectively protect all types of precision equipment, nstruments.
6. Adjustable flow of the circulating pump of the machine can also be customized, great to meet the actual needs of different users.
