Thermo Scientific Forma 29 cf Incubated/Refrigerated Environmental Chamber + Humidity Control

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
