Niles , IL – A line of extremely affordable general purpose water baths is now available from PolyScience. Equipped with economical analog controllers, these versatile water baths maintain bath temperatures from ambient +5° to 100°C with ±0.2°C uniformity and precision. Suitable for a wide variety of general laboratory applications, they are available with 2, 5, 10, 20, and 28 liter stainless steel reservoirs.

In addition to offering excellent performance and reliability, PolyScience Analog Water Baths come equipped with a tilting, see-through polycarbonate cover and -20° to 150°C alcohol thermometer. The steeply gabled cover is particularly ‘lab friendly', accommodating glassware of varying heights and permitting easy loading and removal of samples while allowing condensate to drain neatly back into the bath. An automatic over-temperature safety cuts power to the heater should the bath liquid level drop too low or a control malfunction occur.

Niles, IL – PolyScience is showcasing the DuraChill™ industrial capacity chillers at CLEO 2003 in Baltimore in June. Designed to provide reliable, DuraChill Chillers are suitable for process temperatures from 14° to 104°F (-10° to 40°C) and are capable of providing up to 236,000 BTUs or more of heat removal. Temperature stability is ±2.0°F (±1.11°C).

Portable yet extremely robust, DuraChill Chillers are available in 1½ to 25 HP models and a wide variety of configurations. Standard features include digital microprocessor control with LED temperature readout, digital pressure and flow rate readout, high and low temperature alarms, and remote on/off capability. In addition, each chiller can be equipped with the pump type — centrifugal, positive displacement, or turbine — best suited for the cooling application.

For optimum application and installation flexibility, PolyScience DuraChill Chillers are available with a broad selection of options and accessories. Popular options include wider process temperatures, serial output, remote temperature probe, remote control, DI compatible process piping, and higher output pumps. For added convenience, these versatile units can also be equipped with process shutoff valves, flow meters, recirculating pumps, tank level indicators, automatic water makeup valves and other accessories.
