Product Overview

Controlled Environments for Reliable Stability Studies

The NPD Stability Test Chamber maintains temperatures from 5°C to 60°C and relative humidity from 5% to 90%. It supports widely used ICH Q1A(R2) stability-study conditions including 25°C / 60% RH for long-term testing, 30°C / 65% RH for intermediate testing and 40°C / 75% RH for accelerated testing.

Dual turbo-fan circulation, high-accuracy sensors, programmable cycles and protective alarms support consistent operation over extended study periods. The equipment is suitable for pharmaceutical manufacturing, contract research organisations, quality-control laboratories, cosmetics, food products and packaging development.

The chamber is designed to support ICH/WHO stability programmes; the actual study, qualification and regulatory compliance must be verified independently.

Technology & Construction

Control, Monitoring & Durable Design

A programmable touchscreen controller manages temperature and relative humidity with auto-tuning, alarm functions and an adjustable 0–24 hour day/night timer. Built-in RS-485 communication and RS-232 data-logger support allow traceable measurements. Wi-Fi and LAN monitoring are optional.

The chamber features an SS 304 interior, powder-coated CRCA outer body, 80–150 mm double-wall PUF insulation, a CFC-free hermetic cooling system and dual turbo-fan circulation. An inner full-length glass door improves visibility while limiting disturbance to the test environment.

Safety provisions include low- and high-temperature cut-offs, high-humidity cut-off, low-water-level alarm, automatic water supply and audio-visual deviation alarms. Optional 10,000 lux illumination can support photostability-related workflows.
