Ultra-low temperature chiller for laboratory use
The DLSB-10/120 is a 10L refrigerated circulator that reaches -120°C for chemical reactions and drug storage. It connects to rotary evaporators, jacket reactors and vacuum freeze drying ovens to provide low temperature liquid circulation. The unit operates on 220V/50Hz power with a microcomputer controller and digital display for straightforward operation.
Practical limits of the cooling interface
The circulator delivers a flow of 20L/min with a lift of 4-6m, suitable for standard laboratory glassware connections. Ambient conditions must stay near 25°C and 60-80% humidity with ventilation to maintain the stated performance. No load minimum temperature reaches -122°C while the working range is rated at -120°C with a precision of ±0.2°C.
Reservoir capacity decides suitability
A 10L reservoir volume determines whether this model matches the scale of the application, with other sizes available from 5L to 100L. The refrigeration capacity spans 4997-120W across the operating range, and the machine dimensions are 1050×800×1000mm for bench planning. Buyers needing larger or smaller bath volumes should select a different capacity model.

Questions about this item
Which capacity model from the 5L to 100L range suits a typical rotary evaporator setup?
The 10L reservoir matches the listed volume for this unit; larger volumes such as 20L, 30L or 50L are offered as separate models for higher throughput.
What does the -120 °C rating mean for actual reaction temperature stability?
The no-load minimum reaches -122 °C and the controller holds ±0.2 °C precision, so the bath stays within a tight band around your set-point during reactions.
How does the 220 V / 50 Hz supply limit pump performance in a standard lab?
At 220 V / 50 Hz the circulation pump delivers 20 L/min flow with 4–6 m head, which sets the practical pressure and flow ceiling for connected glassware.
