34 Recirculating Chillers Improve Bioreactor Yield, Reduce Operating Cost


PolyScience offers almost two dozen recirculating chillers designed to maintain bioreactors at the constant temperature required for optimal bacterial and yeast growth. A highly reliable and cost-effective alternative to expensive, inconsistent and wasteful tap water cooling, PolyScience Benchtop Chillers and 6000 Series Chillers help ensure maximum yield in the bioproduction of pharmaceuticals, antibodies and vaccines.


PolyScience Benchtop Chillers offer a compact and easy-to-operate solution for cooling bioreactors up to 10 litres in size, maintaining temperature with ±0.1°C stability and delivering cooling capacities as high as 1610 watts. Seven different models are available; all feature a space-saving design, large easy-to-read LED display and a choice of pumps.


For bioreactors larger than 10 litres, PolyScience 6000 Series Chillers are recommended. They also maintain temperature with ±0.1°C stability and feature large, dual displays that present temperature and pressure or flow rate simultaneously. These chillers are available with cooling capacities as high as 2900 watts, compressor sizes from ¼ to 1 HP, and positive displacement, centrifugal, or turbine pumps.


All chillers feature readily accessible, reusable fluid and air filters, which are easily removed for cleaning, helping simplify maintenance and ensuring energy efficiency.

Economical Recirculator Provides Low-Cost Cooling for Laboratory Applications


An efficient and reliable liquid-to-air recirculator [https://ilmt.co/PL/73dm] that provides exceptionally economical heat removal for FTIR, GC/MS, ICP, vessels, and other laboratory applications is now available from PolyScience. Intended for removing heat loads from sensitive equipment and processes, the Model 3370 Liquid-to-Air Cooler boasts a 4000 watt cooling capacity at 20°C (68°F) and can handle liquid temperatures as high as 70°C (158°F). As a result, it offers significant cost-savings over mechanically refrigerated circulators.


Designed for simple operation and maintenance, the Model 3370 circulates fluid at up to 20.5 lpm (5.4 gpm) to the equipment, back into a reservoir, and through a fan-cooled radiator which removes heat. A built-in low-liquid level indicator safeguards the reservoir and circulation system. The pump and cooling system are further protected with reusable filters. The unit is available with either a turbine or positive displacement pump.


In addition to long life and easy maintenance, the Model 3370 Liquid-to-Air Cooler is also extremely compact. Measuring just 20.5 x 15 x 22.3 inches (52 x 38.1 x 54.6 cm), it requires only slightly more than 1.5 sq.ft. of floor or bench space.

Rapid, Low Cost Liquid Cooling


A line of low temperature coolers that provide rapid, low cost cooling of liquids to temperatures as low as -100°C is available from PolyScience. Available in both immersion probe and flow through styles, these compact systems are ideal cooling exothermic reactions, freeze point determinations, freeze drying, impact testing, lyophilisation, and vapour and solvent trapping.


Excellent for trapping, Dewar-type applications, and the rapid cool down of small volumes of liquids, PolyScience Immersion Probe Style Coolers reduce the expense of using dry ice or liquid nitrogen and are capable of reaching temperatures as low as -100°C. A flexible hose allows convenient placement of the cooling probe. Seven different models as well as a variety of probe types are available.


Capable of reaching temperatures as low as -25°C, PolyScience Flow-Through Style Coolers are ideal for extending the temperature range of non-refrigerated circulators to below ambient as well as boosting the cooling capacity of refrigerated circulators. These coolers also offer an extremely economic alternative to tap water cooling of heated circulating baths when rapid cool-downs or operation at or near ambient is needed.

Digital Water Baths Offer Exceptional Temperature Control and Functionality


PolyScience’s line of economical general purpose water baths combine exceptional temperature control with full-featured digital functionality and ease of operation. Designed to accommodate a wide variety of clinical and laboratory applications, these versatile water baths maintain bath temperatures from ambient +5° to 99°C with ±0.1° stability and ±0.2°C uniformity. They are available with 2, 5, 10, 20, or 28 litre single chamber reservoirs.


In addition to precise temperature control, PolyScience Water Baths feature a digital temperature readout that displays both the actual bath temperature and set point temperature simultaneously, three user-defined temperature preset buttons for the quick selection of frequently used temperature set points and an integrated timer. Bath temperature can be displayed in either °C or °F. For added operational convenience, all models include a steeply gabled tilting cover that accommodates glassware of varying heights and permits easy loading and removal of samples while allowing condensate to drain neatly back into the bath. A high-clearance lid is available as an accessory for larger flasks or bottles. Baths with a 10 litre or large reservoir are also equipped with a reservoir drain. All models come equipped with a diffuser tray.
