-20°C Refrigerated Circulation Bath (-20°C 저온순환수조)
Heated/Refrigerated circulating open bath system capable of reaching temperature as low as -20°C and heating up to 120°C for a wide variety of laboratory heating and cooling applications. Internal circulation of thermal fluid within the bath allows precise uniformity within ±0.1°C. Circulation pump enables to circulates heated or refrigerated thermal fluid to external equipments such applications as reactor, condenser, rotary evaporator or controlling the temperature of laboratory equipment such as chromatography columns, viscometers, and densitometers. External circulation pump capacity 10 liters/min. in flow rate and 0.5 bar in pressure.
