PolyScience Chiller & Accessories

PolyScience specializes in laboratory chillers and recirculating cooling systems engineered to provide accurate temperature control and high heat removal for demanding laboratory and industrial applications. Designed to support liquid temperature control in analytical equipment, pilot plants, and manufacturing environments, these systems help regulate exothermic reactions, stabilize thermal conditions, and protect temperature-sensitive processes. 

The PolyScience portfolio includes PolyScience DuraChill® Chillers, refrigerated circulators, and recirculating coolers available in air- and water-cooled models. These systems offer defined temperature ranges, scalable cooling capacity, and multiple pump options—including turbine pump designs—optimized for continuous cooling and closed-loop operation. User-focused features such as full-color touchscreen displays, temperature and pressure displays, user-adjustable alarms, external temperature tracking, liquid level monitoring, customizable presets, and Eco Mode support efficient and controlled operation in industrial workflows. 

PolyScience accessories, including immersion probe coolers, rigid coil probes, insulated flexible hose, inlet/outlet adapters, and flow-through style configurations, expand system compatibility for applications such as freeze drying, vapor and solvent trapping, cannabis extraction, plastic molding machines, metalworking lasers, and medical diagnostic equipment. 

MSE Supplies offers a curated selection of PolyScience chillers and accessories, providing dependable customer service, fast delivery, and reliable access to temperature control solutions aligned with modern laboratory and process cooling requirements. 

What to know before you buy

This PolyScience collection pairs the chillers and coolers with the fluids, tubing and filters that keep them running. It suits labs cooling rotary evaporators, reactors, analytical instruments and other equipment that sheds heat.

Recirculating chillers pump cooled fluid out to your equipment and back. The DuraChill line includes the PolyScience DuraChill benchtop chiller, 1000W and larger DuraChill CA units at 1.4 kW and 2.9 kW, with either a turbine or a positive displacement pump. Immersion coolers such as the PolyScience IP-100 low temperature cooler drop a probe straight into a bath. A flow through cooler cools water passing through it.

Accessories cover the full loop. Heat transfer fluids include Polycool EG -25, Polycool HC -50 and Polycool MIX -25, plus Polyclear MIX 30 PLUS. Tubing comes in Viton and Buna N, with insulation for 1/2 inch lines. Sediment filters from 20 to 50 micron, air filters, a manifold kit, an external bypass, a PolyScience external Pt100 probe and a caster base round it out.

Frequently Asked Questions

How do I size a PolyScience chiller?

Add up the heat load from the equipment you are cooling at your target temperature, then pick a chiller with cooling capacity above that figure at the same temperature. The DuraChill CA 1.4 kW chiller and the 2.9 kW model cover larger loads than the 1000W benchtop unit.

Should I choose a turbine pump or a positive displacement pump?

A turbine pump moves higher flow at lower pressure and suits open or low-restriction loops. A positive displacement pump holds flow against higher back pressure, which helps with long tubing runs, narrow fittings or equipment with small internal channels, such as the DuraChill CA 2.9 kW chiller with positive displacement pump.

Which PolyScience cooling fluid should I use?

Match the fluid to your lowest working temperature and your equipment materials. The product names indicate the low end, for example Polycool EG -25 and Polycool HC -50. Check each listing for compatibility with your chiller and its seals before you fill the loop.

What accessories do I need to connect a chiller?

You need tubing sized to the chiller ports, such as Viton tubing, 1/2 inch ID, and insulation to cut heat gain on cold lines. A sediment filter protects the pump from particles. A manifold kit splits flow to several instruments, and the external Pt100 probe lets the chiller control to the temperature at your sample.

Can I order several chillers or a full cooling setup at once?

Yes. List the chillers, fluids, tubing and filters you need in a quote request and we can check that the parts match. For repeat orders of fluids or filters in quantity, use the bulk order request form.
