DLSB-500L Low Temperature Coolant Circulation Unit, RT~-20℃, Gongyi Yuhua Instrument Co., Ltd (CAT#: STEM-GLE-0604-YJL)

DLSB-500L Low Temperature Coolant Circulation Unit, RT~-20℃, model DLSB-500L-20 is manufactured by Gongyi Yuhua Instrument Co., Ltd. This product is the latest product developed by our factory. It is a combination of vacuum pump and cryogenic cooling pump. It can not only vacuumize, but also provide low-temperature cooling water, which is a good auxiliary equipment for vacuum distillation and vacuum concentration. It is specially adapted to be equipped with a rotary evaporator, which not only reduces the use space, but also reduces the vacuum degree and saves water resources. It is widely equipped in modern laboratories.

DLSB-series low temperature coolant circulation pump is the latest product developed by our company and colleges and universities on the basis of similar products in Germany and Japan, combined with China's national conditions, reaching the international advanced technology level in the 1990s.
1. Original fully hermetic compressors from world famous manufacturers, advanced performance and reliable quality.
2. The professional relays, protectors, capacitors, etc. of the refrigeration unit are imported original high-quality equipment to ensure reliability and service life.
3. Digital display temperature control, easy to operate and eye-catching.
4. A variety of functions, which can provide low-temperature high-quality cooling water, low-temperature non-freezing liquid, and small low-temperature water bath. It can be combined with circulating water-type multi-purpose vacuum pump, vacuum freeze-drying box, rotary evaporator, magnetic stirrer and other instruments to carry out multi-functional chemical reaction operations and drug storage under low temperature conditions. It can be matched with a variety of large-scale precision equipment to overcome the difficulties that valuable instruments and equipment cannot be used due to poor cooling water, high temperature, and unstable water pressure.
5. It is specially designed for the 220V50Hz mains situation in line with China's national conditions to avoid failures and difficulties in domestic use caused by the 110V, 60Hz design.
6. The circulation system is made of stainless steel, which has the functions of anti-corrosion, anti-rust and anti-low temperature liquid pollution.
7. For high-purity metals, rare substance purification, environmental laboratories, magnetron measurement, vacuum coating equipment and other large-scale precious and expensive experimental equipment, it can provide cooling water that meets the dual requirements of temperature and water quality, with energy saving, water saving, anti- The characteristics of pollution and anti-scaling can effectively protect large-scale precision instruments and equipment.
8. This machine integrates circulating cooling water, with small volume and reasonable power configuration, which fully shows the characteristics of space saving.
9. Meet various conditions of use.
