Forma 3960 Environmental Chamber

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 clinical applications, elevated temperature stability studies, and shelf life testing

Digital display can be read and set in 0.1°C increments

Heated glass door for minimal condensation and a clear view

Interior and exterior convenience receptacles

Swivel, locking casters ensure easy mobility during installation and cleaning. Leveling feet provide stability and added safety in the lab.

Thru-wall access ports (2.4" with stopper), located on the right and left sides of the chamber, make it possible to add probes, sensors, etc. without altering the cabinet.

Interior GFCI duplex receptacle located in the upper right corner of the rear wall permits the use of shakers, cell rollers, and other equipment inside the chamber, eliminating the inconvenience of an extra external power strip.

Exterior receptacle, located on the upper-right side of the control panel, is available for connecting an optional recorder or other equipment.

Low Alarm: User programmable and indicator

Over-temperature alarm can be set with 0.1°C precision and is programmable with "action" (shuts off heat) and visual indicator

Includes NEMA 5-15P Plug

Standard remote alarm contacts and available data outputs (RS-485, 0-1V, 0-5V, 4-20 milliamp) allow connection to an in-house monitor/alarm system to track chamber conditions, helping you meet internal and regulatory documentation requirements

Directed Horizontal Laminar Airflow System

Horizontal Laminar Airflow System
Horizontal Airflow

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.

Intuitive, Powerful Enviro-Scan Controller

Ensures precise temperature control without complicated programming

Provides audible/visual under-temperature and over-temperature alarms for peace-of-mind

Includes an easy-to-read display for convenient, continuous monitoring

Pperating modes include Run, Setpoint, Calibration, and System Configuration

Rugged Construction and Durable Shelving for Long Life

Exterior cabinet is 18 gauge cold-rolled steel, powder coated for durability and a high quality appearance that resists scratches and chipping.

Maximum product thermal protection and added cabinet strength for reliable daily use are provided by the 2-inch thick fiberglass cabinet insulation

Solid, stainless steel interior is more durable and corrosion-resistant than plastic or painted metal, ensuring long life and minimizing equipment costs.

Five heavy-duty, solid, stainless steel shelves, adjustable on 2.0" centers, are easy-to-clean, saving time and effort; more corrosion-resistant than coated wire shelves for long life; and adjustable for convenience.
