HOLYSCIENTIFIC is one of the leading science equipment manufacturer & exporter our equipments are widely used in many industries like laboratory sterilization, clean room, microbiology, pathology, bio technology, pharmaceuticals, seed & soil testing, metallurgical, food processing and many more. Our stability chamber are widely used in pharmaceutical companys, biomedical storage, food processing and many other industries.


Stability chambers are environmental test chambers used to test the effects of specific environmental conditions on products and specimen. By allowing precise control and consistent temperature and moisture conditions within the chamber, a researcher can use the stability chamber to measure the effects of humidity and temperature on objects by manipulating these factors.


we are leading manufacturer of stability chamber also known as humidity chamber and environmental chamber. Our stability chamber has double wall construction. Inner chamber made of thick highly polished stainless steel 304 sheets with self support for wide range of shelf spacing. Supplied with three perforated shelves. (As per model) Exterior made of thick mild steel sheet duly finished in enamel paint or pastel mat finish colour combination.

Stability 600 400 - Shaking incubator manufacturer

Outer double wall door is provided with magnetic gasket and lock & key arrangement. Inner door of our stability chamber is made of clear acrylic sheet of glass allowing inspection of material in the chamber without disturbing the chamber temperature. Door operated inner illumination has been provided. The gap between walls of equipment are filled with PUF (poly urethane form) which insures maximum thermal efficiency as well as reduce power consumption in our Stability chamber. Air circulation fan provided to make air circulation throughout the chamber. The temperature can be regulated within the range by means high precision double action controller. Castor wheel for easy movement. Fins type S.S tubular heater for stabilized accurate process temperature. A control panel is provided with various indicators lick ON/OFF switch cord plug, Heater indication lamp, etc.
