Deep Freezer

Deep Freezer

Labtop freezers are designed for storing of blood component , Vaccine , serums , Biological and medical specimens These freezers are also commonly used in several research organizations, medical centres, research laboratories and pharmaceutical industries for storage of micro organisms and other chemicals at -20.0Β°C.
Labtop Freezer are exclusively used in Pharmaceutical manufacturing, Biotechnology, Personal product manufacturing, Hospitals and Research centers, Clinical research, Seed Industries, Research and development Laboratories ,Universities and extensively used Quality control, Microbiology , Pathology Labs etc.. Labtop chambers conform to International Standards such as ICH, WHO Guideline, and USFDA requirements.

cabinet construction

The cabinet of Labtop Chambers is insulated with high density CFC free Poly Urethane Foam. Interior of the chambers are mirror finish stainless Steel (304 SS, 1.0 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. GMP models are in total stainless steel (Inside S. S 304 with mirror finish and outside. S.S 304 dull finish and inner S.S316 is also available on request at extra cost ) and the unit is mounted on caster wheels for ease of mobility.

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.
