Circulators, chillers & thermostats

A bath circulation thermostat is a control unit with heater, temperature controller and pump that sits on a bath or comes as a bath combination. It holds the bath fluid at a set temperature and circulates it, so the whole bath is uniform and, often, an external device can be temperature-controlled too.

Choose a heating circulator if you only work above ambient. If you need temperatures below ambient, fast cool-down or must remove reaction heat, choose a refrigerated circulator. It has a built-in refrigeration unit and can both heat and cool.

Yes, if the circulator has a pump with external connections. The bath fluid then circulates through tubing to, for example, a jacketed reactor, a refractometer, a viscometer or a rotary evaporator condenser. Check pump pressure and flow, and use suitable tubing from our temperature control accessories.

A refrigerated circulator has its own bath and controls temperature precisely, heating included. A recirculating chiller removes heat from equipment such as condensers, rotary evaporators or lasers, often replacing tap-water cooling. A chiller usually controls less finely and generally does not heat.

That depends on the unit and the range you work in. Water suits the usual range, water-glycol mixtures lower temperatures and thermal oils higher temperatures. Always follow the fluid table in your unit's manual or on the product page, and respect flash point and viscosity limits.

A circulator or thermostat holds a bath liquid at a set temperature and pumps it through a jacket. A chiller is the same idea aimed below ambient. The temperature range, the cooling power and the pump flow are the three numbers. The fluid has to match the range.

Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
