CIBAC45 Cooling Circulating Bath · −10 to 100 °C · 7.3 L · ±0.1 °C
The cooling circulating bath CIBAC45 cools and heats liquid from −10 °C to 100 °C and holds it within ±0.1 °C. The 7.3 L stainless steel tank takes samples directly, and the pump sends the liquid through hoses to a rotary evaporator condenser, a jacketed reactor or another instrument that needs a constant temperature.
Cooling circulating bath for the bench
The CIBAC45 cooling circulating bath combines a compressor, a heater and a circulation pump in one unit. Below room temperature it replaces tap water or ice for cooling a condenser; above it, the same bath works as a heated water or oil bath up to 100 °C. Switch between internal circulation, which keeps the tank uniform, and external circulation, which carries the liquid to a connected vessel and back.

All cooling circulating bath models: stability ±0.1 °C, pump 0–15 L/min, 7-inch touch screen. Order codes, power and outer dimensions of every model are in the CIBAC technical specification (PDF).
Which model to choose
To choose a cooling circulating bath, start with the lowest temperature you need, then the tank size. CIBAC45 covers −10 °C with a 7.3 L tank; with the same tank CIBAC46 goes to −20 °C, CIBAC47 to −30 °C and CIBAC48 to −40 °C. For more liquid or larger vessels choose the 10 L, 15 L or 29 L models. When you only need to heat, see the PURUS thermostatic water bath, and when the samples must also be shaken the ORSHAWB shaking water bath.

Installation and bath liquid
Leave 300 mm free space behind and on both sides of the cooling circulating bath for ventilation and connect it to an earthed socket. Keep the liquid at least 30 mm below the top of the tank. Use ethanol or a water–glycol mixture below 5 °C, pure water from 5 to 80 °C, water with about 15 % glycerol from 80 to 90 °C and silicone oil above 90 °C.
