A selection of chillers and refrigerated circulating baths that provide precise temperature control for analytical instrumentation is available from PolyScience.
Designed to control temperature with stabilities as precise as ±0.005°C, PolyScience Refrigerated Circulators and recirculating Chillers are suitable for maintaining atomic absorption (AA) furnaces, gas chromatographs, mass spectrometers, inductively coupled plasma (ICP) and other analytical equipment at optimal working temperatures.
Refrigerated Circulators are recommended for applications where a broad temperature range and/or ultra-precise temperature control are required.
They maintain temperatures over ranges as wide as -40° to 200°C with up to ±0.005°C stability and deliver from 200 to 1400 watts of cooling at 20°C, and are available with reservoir sizes from seven to 75 litres.
Products come with a choice of six different temperature controllers, including two programmable models.
For applications requiring higher cooling capacities, PolyScience Chillers may be more appropriate. Available in both benchtop and portable models, the air-cooled units deliver between 460 to 5200 watts of heat removal at 20°C.
They provide working temperatures as low as -20°C and as high as 70°C, stabilities as precise as ±0.1°C, and are offered with a variety of pump options.
