Our list of products for different applications


These are medium to large-sized chambers that are custom-built to ensure that they not only fit optimally in your lab's stability area but also address your large-scale stability testing requirements.

Walk-In Chambers have now become a de-facto requirement for companies planning multiple ANDA filings & planning to launching various products simultaneously.

NEWTRONIC Walk-Ins ensure a smooth air-flow pattern to improve the temperature & humidity distribution across the chamber. This has also led to huge load reduction on the heating, cooling & humidifier systems. This & many other innovations in the construction & design aspects have ensured dramatic reduction in power consumption of our Walk-Ins.

NEWTRONIC has also been regularly exporting the Walk-In Chambers to all the major markets of the world. We ensure our products meet all kinds of country-specific requirements such as voltage specifications, regulatory needs, container shipping, etc
