Thermo Scientific Forma environmental chambers are built to last and will meet your needs now and in the future. These high precision cabinets meet ICH, FDA, TAPPI, ASTM, and other national testing standards.

• Meets International Conference on Harmonization (ICH) guidelines for drug substance and product storage testing
• Ideal for drug stability studies, shelf life testing for packaged products, and insect and other large-scale biological research
• A broad temperature range and optimum temperature uniformity and recovery contribute to an ideal test environment, even when the chamber contains large product loads and low output, heat-generating equipment
• Control: ±0.1°C @ 25°C to 37°C (77°F to 98.6°F)
• Sensor Type: RTD
• Microprocessor PID controller which is programmable with 24 Ramp and Soak Steps
• Digital Dual LED display can be read and set in 0.1°C increments; one digital setpoint
• Audible and Visual high/low temperature alarm
• Refrigeration is accomplished by a 1/4 HP, air-cooled compressor and Non-CFC, R134A refrigerant
• Fittings include a drain port on the bottom - 3/8 in FPT and 3/8 in O.D. P-trap right rear; Fill Port - 1/8 in female NPT
• Includes NEMA 14-20P Plug
• Dry Contacts for Common, NO, NC
• Standard 4 to 20 milliamp output connects to most alarm/monitoring systems, allowing you to meet internal and regulatory product documentation requirements
• NOTE: Drain Required unless fitted with the optional Condensate Evaporator (Model 1900031 below in accessories)
• Directed airflow minimizes the risk of product desiccation and loss, and wasted time and money due to poor temperature uniformity and recovery
• Promotes an ideal growth environment far surpassing the efficiency of a top-to-bottom, undirected airflow design
• Includes a positive pressure feed plenum on the right side of the chamber and a negative pressure return plenum on the left to distribute the airflow uniformly throughout the chamber
• Even when filled with samples or equipment, each shelf receives a consistent flow of conditioned air for optimum temperature uniformity and recovery
• Directed airflow prevents deterioration of temperature uniformity and recovery when shelves are full because airflow is not blocked
• By design, the feed plenum cannot be blocked by the chamber's contents
• Exterior cabinet is 18 gauge cold-rolled steel, powder coated for durability and a high quality appearance that resists scratches and chipping
• 2.0 in (5.1 cm) thick, non-CFC, foamed-in-place polyurethane cabinet insulation provides maximum product thermal protection and increased rigidity for reliable daily use
• Phenolic-coated evaporator protects against corrosive by-products or agents in the chamber atmosphere (e.g., secretions from insects such as flies), ensuring long life
• Solid, stainless steel interior is more durable and corrosion-resistant than plastic or painted metal, ensuring long life and minimizing equipment costs
• Heavy-duty, solid, stainless steel shelves are easy-to clean, saving time and effort; more corrosion-resistant than coated wire shelves for long life; and adjustable for convenience
• Swivel, locking casters ensure easy mobility during installation and cleaning. Leveling feet provide stability and added safety in the lab
