Product Overview

The Ratek Shaking waterbath is suited to a variety of procedures where temperature controlled water and agitation is required. For added versatility the waterbath and shaker have individual controls and can operate independently of each other, actual bath temperature is shown on the LCD. When the shaking cradle is removed a perforated stainless steel panel (supplied as standard) supports flasks and containers. The platform drive has 4 different travel settings and incorporates slow acceleration to reduce the risk of spillage. Food grade polished stainless steel is used for the tank and platform components, the outer case is manufactured from a corrosion resistant plastic to provide durability. An optional rack (RR20) consisting of adjustable horizontal bars attached to the shaking cradle is available to secure flasks and containers if required. For accurate temperature control and to minimise loss of water through evaporation, gabled lids made from stainless steel or polycarbonate are available.

Waterbaths are utilised in a wide variety of biomedical, life science, and industrial applications as well as in commercial kitchen cooking techniques such as Sous Vide. Specific applications include Cell Cultures, Cell Aeration, Increasing Solubility Rates, Molecular Biology Assays, Bacterial Cultures and Hybridisation Applications.
