About this category
CSZ stability chambers hold a tightly controlled temperature/humidity environment for pharmaceutical shelf-life work to ICH Q1A — long-term (25°C/60% RH), intermediate (30°C/65% RH), and accelerated (40°C/75% RH) conditions, at +2°C to +70°C. Two reach-in lines cover the range: PharmaEvent (C/280–C/2000), the precision line holding ±0.1–0.2°C under the S!MPAC® pharma controller, and StableClimate® II (ST/STH 24, 52, 82) with a plug-in single-door option and the broader 20–95% RH range. Both carry a 21 CFR Part 11 controller per the manufacturer’s declaration, with IQ/OQ/PQ documentation available — one family, two answers, same ICH Q1A target. Pick the line by the tolerance the protocol audits, then the size by the batch — Prater Technical works with you to spec the right CSZ stability chamber.
