ASAP Chambers

Our Accelerated Stability Assessment Program (ASAP) reach-in chambers deliver exceptional performance for testing applications where vast temperature and humidity ranges are needed.

ASAP testing can significantly reduce the time and resources required for stability testing. However, because this approach requires more extreme environmental conditions, ASAP reach-in chambers must meet exacting standards. Our chambers are engineered to deliver stringent volumetric uniformity and designed for compliance with International Council for Harmonisation (ICH) Q1A.

We’ve provided ASAP reach-ins to leading pharmaceutical companies, food and beverage producers, cosmetics brands, medical device manufacturers, and others. Our chambers are suitable for a wide range of applications including:

  • Biomedical storage
  • Stability research
  • Drug research
  • Extended range testing
  • Packaging studies
  • Freeze/thaw thermal cycling

Versatile ASAP Chamber Design

Our reach-in chamber product line includes seven standard models designed to meet virtually any storage need. Broader customization options are available.

  • Temperature setpoint of +70°C, with accuracy of +/-1°C or less
  • Maintain 10- to 98-percent relative humidity (RH), with accuracy of +/-5 percent or better
  • CO2 injection
  • Volumetric uniformity (horizontal and vertical)
  • Controlled humidification
  • Twenty-two-gauge, stainless-steel interior
  • Scratch-resistant enamel exterior
  • Three-inch, closed-cell urethane insulation to promote superior temperature stability and minimal heat transfer
  • Heavy-duty door hinges, full peripheral magnetic door gaskets, and positive-action latch with lock for a secure, uniform seal
  • Shelving supports up to 130 pounds of distributed load
  • Floor models have individual non-marking casters with adjustable leveling feet for easy installation

We can design our ASAP chambers to meet a variety of highly specialized requirements, including:

  • High RH
  • External stainless-steel construction

  • “Thanks again for the support in getting us to this stage eventually – finding an incubator that meets our temperature spec has been a challenge for us for the last few years and this is a significant milestone for the business. Hopefully we will have more good news to report in the new year.”

    Project Engineer, Major Biotechnology Manufacturer

  • “During a recent external audit, an inspector requested the PM/Cal documents for the stability chambers. It was my pleasure to give him the nicely presented binders. I could tell he was impressed.

    Thanks for the great service you have provided for us over the years.”

    Teresa P, Taste Texture and Health, DSM-Firmenich

  • “Environmental Specialties has always provided me with great service. All the individuals I worked with were knowledgeable about ES products and services.  They were highly skilled. I relied on ES for pm, calibration, qualification, repair, chamber sourcing and consultations. I interacted with a lot of your employees.  The feedback was always spot on. They were always smiling and supportive even in the most difficult situations. ES is a great company with good people.”
