Brinkmann MGW Lauda RM6 Refrigerated Heating Circulating Water Bath Chiller

Brinkmann MGW Lauda RM6 Refrigerated Heating Circulating Water Bath Chiller

The Brinkmann MGW Lauda RM6 is a refrigerated heating circulating water bath combining a temperature-controlled bath, a built-in refrigeration unit, and a circulation pump in a single freestanding instrument. It is capable of both heating and cooling the bath fluid and pumping it to and from external vessels, making it a versatile temperature-control platform for laboratory applications. The RM6 was manufactured by MGW Lauda of Germany and distributed in the United States by Brinkmann Instruments.

Applications

Refrigerated circulating water baths like the MGW Lauda RM6 are standard temperature-control instruments in chemistry, biochemistry, and general laboratory environments. They are used to maintain external glassware, reactors, rotary evaporators, and viscometers at a precise temperature by pumping temperature-controlled fluid through jacketed vessels or coils. The ability to both heat and cool from a single unit makes them well suited to applications requiring stable sub-ambient temperatures as well as elevated temperatures — including enzyme assays, crystallization studies, polymer viscosity measurements, and chemical reaction control. The MGW Lauda line, produced in Germany and widely sold through Brinkmann in North America from the 1970s through the 1990s, developed a strong reputation in research and industrial labs for robust build quality and reliable temperature control. Units like the RM6 remain in use today in labs that maintain legacy glassware setups or require a durable, repairable recirculating bath.
