Heating Bath Circulators – Programmable CW3 Series
Overview
These commonly used CW3 Series circulating baths are ideal for external temperature control of jacketed reactors, rotary evaporators or other such usual temperature control tasks. The bath opening also allows for experiments to be carried out directly in the bath. Four models cover the range for standard applications offering temperature control from Ambient +5 to +150ºC and bath capacity of 5, 10, 20 and 30 liters.
The CW3 programmable heating circulators are advanced models, offering 10 programs for temperature ramp up and dwell control with up to 10 steps per program and 99 hours and 59 minutes per step. Stored programs are easily linkable and programs can be repeated to up to 99 cycles. Pre-hearing and heating time can be set before program starts.
Test tube and spring wire racks are available.
