Stability Chambers TH series for pharmaceutical stability testing
ASLI TH-series constant temperature and humidity chambers deliver precise environmental control for ICH-compliant stability studies, accelerated aging, temperature cycling and reliability testing. Available in pre-engineered TH-80 to TH-1000 models or custom configurations, these chambers offer selectable temperature and humidity ranges, comprehensive safety protections, data logging and energy-efficient refrigeration.

Applications

• Pharmaceutical stability testing — long-term and accelerated ICH studies for drug substances, drug products and excipients
• Biopharma & biotech — stability and shelf-life evaluations for biologics and intermediates
• Medical devices — environmental conditioning and reliability tests for devices and components
• Analytical & QC laboratories — controlled environments for method validation and sample conditioning
• Packaging & cold chain validation — damp heat and temperature cycling for primary and secondary packaging
• CROs and stability facilities — standardized test conditions for regulatory submissions
• Universities & research institutes — reproducible environmental testing for materials and formulations
