CABINET CONSTRUCTION
The cabinet of Chambers is insulated with high density CFC free Poly Urethane Foam. Interior of chambers is 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. Stainless steel trays are provided for storage inside. The cooling is effected by hermetically sealed compressor of high quality. GMP models are in total stainless steel (Inside S. S 304 with mirror finish and outside. S 304 dull finish and inner 316 is also available on request.)
