Environmental Cycling And Simulation Testing

Environmental Cycling And Simulation Testing 2018-05-10T07:13:21+00:00

Whitehouse Labs operates and array of precision Cincinnati Subzero (CSZ) temperature/humidity chambers and data acquisition equipment. These high quality and reliable chambers are fully programmable for profile cycle testing including…

  • Thermal performance of packaging
  • Product quality and reliability
  • Product life expectancy
  • Drug Stability protocols
  • Forced Degradation Studies

Thermal cycle testing is important for product and package development in order to ensure that adverse affects from extremes in climatic conditions do not harm the efficacy of drug products; packaging protects products from excursions in temperature and humidity; and packaging itself does not deteriorate under extremes in climatic conditions (e.g. dry desert, tropical, etc.).

For example; chambers are used specifically for cold chain packaging to validate they are performing as intended and designed for shipping drug products. Accelerated aging protocols are performed in the CSZ chambers to confer shelf life claims to medical devices. Capabilities are shown below:


Climatic Description Temperature Range
Walkin Environmental Chambers for Larger Projects 30°C to +60°C +23°C ± 1°C /50% RH ± 2%
Reach in and Bench Top Chambers for developmental studies -70°C to +190°C
ICH Refrigerated Long-Term Storage +5°C ± 3°C
ICH Long-Term/Accelerated (Refrigerated +25°C ± 2°C /60% RH ± 5%
ICH Intermediate (Zones I, II, III and IVa) +30°C ± 2°C /65% RH ± 5%
ICH Long Term (Zone IVb) +30°C ± 2°C /75% RH ± 5%
ICH Accelerated (Zones I-IV) +40°C ± 2°C /75% RH ± 5%
Long-Term (Frozen) -20°C ± 5°C ICH
Cryogenic Storage -70°C through -90°C
