Compact Stability Chamber 70-250 L, 45-95% RH, 5-65°C, 30-Segment Program, Glass Inner Door

The Master Science Compact Stability Chamber brings temperature and humidity control into a smaller footprint, with sizes from 70 to 250 litres. It suits labs that run stability or storage studies on a modest number of samples and do not need a walk-in or large cabinet.

Without humidification the chamber covers 5 to 65°C; with humidity control it works from 10 to 60°C and 45 to 95% RH. A PT100 sensor and PID controller handle temperature, a capacitive humidity sensor with anti-condensation design handles RH, and a 30-segment program allows step and loop profiles. Double doors with a glass inner door let you look at samples without disturbing the climate inside.

Testing Problems the Master Science Compact Stability Chamber Solves

Small labs often lack a dedicated, controllable climate for stability work. The Master Science Compact Stability Chamber helps with:

• No controlled humidity: Built-in humidification holds 45-95% RH.
• Conditions disturbed by checks: The glass inner door keeps the climate stable.
• Running out of water unnoticed: A water shortage alarm warns in time.
• Controller failure risk: An independent mechanical limiter adds protection.
