Protect your delicate samples

Your samples are delicate, often irreplaceable. You depend on consistent performance from your equipment throughout your work, from sample preparation to storage.

Thermo Scientific Forma Environmental Chambers feature proven technology for outstanding temperature uniformity and stability.

Stability Chambers

Stability Chambers provide a controlled temperature and humidity environment. They are perfect for stability tests, e.g. in Pharma or packaging. Other applications include environmental testing or controlled storage.

Reach-in Chambers

Reach-in Chambers are heat only and provide a controlled temperature environment above the ambient temperature. Typical applications are microbiological incubation, or controlled storage. High volumes of samples can be incubated, tested or stored.

Vertical Light Chambers

Vertical Light Chambers are perfect for light stability testing, plant growth or animal hatching. The samples are exposed to the light from above, temperature + humidity can be controlled. Choose from various different light modules to address the specific application.

Reach-in incubator for elevated temperature applications

Reach-In Refrigerated incubator broad temperature range covers incubation, testing and storage applications that require temperature control.

  • Reliable temperature control
  • Adjustable high and low temperature alarm prevents operator of deviations
  • Large chamber to accommodate large sample amounts 

Reach-in chambers for elevated application temperatures

Choose from various door options:

  • Exterior glass door for best view on samples is standard
  • Exterior solid door for light sensitive applications
  • Exterior solid door with interior glass door for incubation applications

Optional Cell Roll System

An optional cell roll system allows extensive production of monolayer cell cultures in standard roller culture vessels. This helps improved oxygenation and exposure of the cells to the media growth area. Combined uniform temperature control and continuous, gentile rotation provided by the cell roll system create the ideal conditions to help increase culture yields.

  • Cell roller up to 7 decks high with 5 positions per deck for a maximum total of 35 positions, or bottles.
  • Maximum capacity includes a Three-Tier Cell Roller Base (15 positions), four add-on tiers (20 positions), and a reinforced floor/ramp.
  • All position drive is standard. Adjustable speed contro lwith speeds of 0.125 to 6.25 RPM with ±1.0% accuracy, based on 110 mm bottles.

Vertical Light Chambers address a variety of applications that require sample exposure with light, along with temperature control and humidity.

  • Flexible set up addresses requirements for sample distance to light and sample volume
  • ICH light module for optimal light exposure according to guideline Q1B. Order desired number of modules separately
  • Specific light modules for plant growth and animal hatching also available
  • Solid door ensures there is no "light pollution" in the light exposure to samples

Address applications under optimal conditions with light choices. Wide light distribution is achieved with 7 fluorescent light bulbs. 

The Thermo Scientific Directed Airflow System

The Thermo Scientific Directed Airflow System versus a top-to-bottom, undirected airflow design. The directed airflow minimizes the risk of product desiccation and loss, and wasted time and money due to poor temperature uniformity and recovery. The horizontal airflow of Thermo ensures great temperature uniformity and stability values - even with many samples on the shelves.

Temperature / humidity performance chart

The chart illustrates the maximum and minimum attainable humidity within the cabinet at a given set temperature under the following nominal conditions: refrigeration on, defrost off, no wet bulb recorder, no air exchange, set for 22.2°C (72°F) and 50% RH ambient. Optional heatless dryer is available for lower humidity levels.
