Humidity and Temperature Stability Testing Chambers

Top-of-the-line environmental test chambers, in sizes from 24 to 80 cubic feet

• Reliable temperature and humidity control - worry free
• Alarms and alarm logging - easy recordkeeping
• One-, two-, and three-door units - to fit your lab

A large capacity high humidity stability testing chamber with microprocessor and alarm logging for reliable control and simplified recordkeeping.

Features

An environmental test chamber you can depend on. Microprocessor control of temperature, humidity, and a control panel message center for easy monitoring. With a programmable ramp soak feature, this chamber meets your demanding requirements for drug stability testing.

Control System

A modular system with state-of-the-art logic microprocessor and multifunction keypad. Includes:

• Ramp soak (fully programmable)
• Product and air temp (C°) scale
• Alarm/temp logging
• System mode indicator: heating/cooling
• Real-time clock
• Alarms
• Hi/low visual alarms
• Power failure
• Sensor failure
• Service prompts
• User password entry
• RS485 interface (optional)
• Expansion slots for future additions

Conditioning System

Precision control - uniform air distribution through a ceiling plenum, which delivers air evenly throughout the chamber for max uniformity and efficiency. Heavy duty refrigeration system for rapid removal of heat caused by door openings or product load.

Includes an expansion valve system to optimize capacity and efficiency, and an Incoloy® tube heater.

Construction

Insulation provides low heat transfer, improved cabinet performance and prohibits moisture from migrating into cabinet walls. Thermostatically controlled door heater wire for energy savings.

• Creek Chub Tissue Reflects Environmental Contamination

  In 1997 the Office of Water Quality of the Indiana Department of Environmental Management (IDEM) instituted a new monitoring policy.  Instead of just sampling water, they began sampling fish also. Sampling fish tissue enabled the “environmental scientists to measure the regional magnitude and extent of fish tissue contamination by specific bioaccumulating elements or compounds.” After

• Laboratory Refrigerator Sets Conditions for Apple Juice Testing

  One of the complaints about modern foods is that they’re “over-produced”—processed to the point where they bear little resemblance to the actual food they purport to be.  You probably recognize the artificiality of “cheese” in a can or the pressed meat product in a five-pound oval tin that purports to be “ham.”  But even products

• CDC Surveys Environmental Hazards to Help Monitor Public Health

  The CDC is carrying out a National Health and Nutrition Examination Survey (NHANES).  It’s a comprehensive series of studies, including both interviews and physical examinations.  The survey is designed to provide a snapshot of “the health and nutritional status of adults and children in the United States.”  The full survey is composed of subsets focussing

• Chicken Fat Spill Minimally Impacts River Invertebrates

  What harm can 7000 pounds of chicken fat do? Well, if it’s in a french fry factory, the harm would probably be measured in terms of lipid pools in arterial walls, but if that 7000 pounds of liquid fat makes its way into a stream in the middle of Missouri, then what?  That’s what the

• Keeping Samples in Lab Refrigerator Improves Test Accuracy

  Immunochemical assays offer an alternative test for colorectal cancer.  The traditional assay requires that patients don’t eat citrus, meat, cantaloupe, or any of a variety of other foods for three days prior to testing; so an alternative test that doesn’t require all that preparation would be useful.  It turns out, though, that one particular immunochemical
