Stability Chamber

Touch-screen PLC controlled temperature and humidity chamber that holds ICH storage conditions such as 25 °C/60 % RH and 40 °C/75 % RH, used by pharmaceutical QC and R&D laboratories for long-term and accelerated stability studies. Also printed as Humidity Chamber.

Typical applications

  • ICH long-term stability storage
  • Accelerated stability studies
  • Pharmaceutical shelf-life determination
  • Drug and drug substance testing

Worth knowing before you order

Stated by the manufacturer as designed to ICH guidelines, but no guideline number is printed anywhere in the brochure. If your protocol has to cite ICH Q1A(R2) or Q1B, ask us to confirm it in writing before you order — we will not assert it for them. No photostability model with UV/visible lux-hour lighting is offered. The manufacturer also prints ISO 9001:2015 (certificate, not a test method) and ISO 9001:2008 (certificate, not a test method). Those are not test methods for this instrument, so they are not listed as conformity above — ask us for the certificate itself if you need it.
