Centrifuges

A centrifuge is an apparatus that is driven by an electric motor and works on the principle of sedimentation, where the centripetal acceleration produced by the rotational force of the machine, cause more dense substances to settle in the bottom and the lighter ones on the top. The centrifugal machine does helps in separating the components of the liquid. These centrifuges are most commonly used in chemistry, biology and biochemistry laboratories for isolating and separating suspensions of proteins, chemicals, etc. They vary in speed and capacities.

cabinet construction

The cabinet of Labtop Refrigerated Centrifuges are insulated with high density CFC free Poly Urethane Foam. Interior of chamber is dull finish stainless Steel (304 SS, 3.0 mm thick). The exterior is white powder coated (3.0 mm thick) mild steel

refrigeration system

The cooling is effected by CFC free refrigeration system with a condensing unit located inside the chamber. Labtop condensing units are characterised by high-efficiency heat transfer and low power consumption.
