NPD Stability Test Chamber
NPD Stability Test Chambers provide controlled climatic conditions for long-term, intermediate and accelerated stability studies. Designed for pharmaceuticals, cosmetics, food, packaging and chemical products, they combine precise temperature and humidity control with uniform airflow, programmable operation and data logging.
Custom chamber configurations available on request.
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.

Dual fans, cooling and humidity systems sustain uniform conditions.
Monitor & Record
Review alarms and export or log test data for study documentation.
ICH Q1A(R2) Study Conditions
Standard study settings referenced in the supplied product documentation.
Long-Term
25°C ±2°C and 60% RH ±5% RH.
Intermediate
30°C ±2°C and 65% RH ±5% RH.
Accelerated

The chamber is designed to support ICH/WHO stability programmes; the actual study, qualification and regulatory compliance must be verified independently.
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.
Applications & Use Cases
Reliable stability studies for research, production and quality assurance.
