plasma freezers

Labtop micro controller based plasma freezers are designed for quick freezing and storing of Plasma and related blood components at -40.0 ºC. These freezers are designed for Blood banks and research laboratories


The cabinet of Labtop Chambers are insulated with high density CFC free Poly Urethane Foam. Interior of the chambers are mirror finish stainless Steel (304 SS, 0.8 mm thick). The exterior is white powder coated (1.0 mm thick) mild steel and the door has magnetic gasket with a keyed door lock. Specially designed solid stainless steel wire mesh trays ensure even temperature distribution and storage inside


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.



A programmable logic controller (PLC) is a digital computer used for automation of controlling electromechanical processes, such as control of Temperature, Speed, Standby systems and event management with less maintenance hence no moving parts.
