Thermo Scientific 3920/3940/3911 Series Stability
Chambers for a Multitude of Applications

This series of environmental chambers meets
International Conference on Harmonization (ICH)
guidelines* for drug substance and product storage
testing. The units are ideal for drug stability studies,
shelf life testing for packaged products, and insect
and other large-scale biological research.

Optimum uniformity and a wide
temperature range for easy compliance
with regulatory requirements

These chambers feature a 0°C to 60°C (32°F to 140°F)
temperature range that can be set in 0.1°C
increments. The 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.

Advantages of our directed horizontal
laminar airflow system

Our directed airflow system (shown below) promotes
an ideal growth environment. The enhanced 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.

This combination directs air across the surface of
each solid shelf. Even when filled with samples or
equipment, each shelf receives a consistent flow of
conditioned air for optimum temperature uniformity
and recovery.

As opposed to our horizontal airflow system, top-to­bottom (non-directed) airflow systems use a top­mounted fan to push air down through wire shelves.

Temperature uniformity and recovery can deteriorate
quickly when shelves are filled because air movement is
blocked. That variation in temperature, alone or when
combined with frequent door openings, may
compromise environmental conditions or make process
validation difficult.

Standard 4 to 20 milliamp output connects to most
alarm/monitoring systems, allowing you to meet
internal and regulatory product documentation
requirements. Chart recorders are also available.

The Thermo Scientific directed airflow design (left) versus a top-to-bottom, undirected
airflow design (right).

The directed airflow minimizes the risk of product desiccation and loss, and wasted
time and money due to poor temperature uniformity and recovery.

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.

• 2.0" (5.1cm) thick, non-CFC, foamed-in-place

polyurethane cabinet insulation provides maximum

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

Cell Roll System

The optional cell roll system allows extensive production of monolayer
cell cultures in standard roller culture vessels. Oxygenation and
exposure of the cells to the media growth area are improved.
Culture yields are increased by the uniform temperature control and
cell roll system’s continuous, gentle rotation.

The environmental chamber accommodates a cell roller up to
7 decks high with 5 positions per deck for a maximum total of
35 positions, or bottles.

Achieving maximum capacity requires a 4862 (4868) 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 control provides
precise speeds of 0.125 to 6.25 RPM with ±1.0% accuracy, based
on 110mm bottles.

Uniformity and an Elevated Temperature Range
for Easy Compliance with Regulatory Requirements

Our directed airflow system promotes an ideal growth environment. The proven design includes a positive
pressure feed plenum and a negative pressure return plenum. This combination directs air across the surface
of each solid shelf. Even when filled with samples or equipment, each shelf receives a consistent flow of
conditioned air for optimum temperature uniformity and recovery. By design, the feed plenum cannot be
blocked by the chamber’s contents. (Refer to the diagram on page 3.)

Intuitive, powerful Enviro-Scan–
a key Forma advantage

> 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.

• Enviro-Scan operating modes include Run, Setpoint,

Calibration, and System Configuration.

• Standard remote alarm contacts and available data outputs

allow connection to an in-house monitor/alarm system to track
chamber conditions, helping you meet internal and regulatory
documentation requirements. Chart recorders are available.

Durable construction and shelving

Valuable features included for cost-

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 2.0" (5.1cm) 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"

(5.1cm) centers, are easy-to-clean, saving time and effort; more
corrosion-resistant than coated wire shelves for long life; and
adjustable for convenience.

• Reinforced floor/shelf components are available so you can use shakers,

cell rollers, or other heavy equipment or product loads inside the
chamber to meet a variety of applications.

effectiveness and flexibility

Casters, access ports, convenience receptacles, heated glass door, and
remote alarm contacts – all are included up-front. Our 3960 Incubator/
Environmental Chamber is prepared to meet your changing application
needs without the added cost of expensive add-on options.

• Swivel, locking casters ensure easy mobility during installation and

cleaning. Leveling feet provide stability and added safety in the lab.

• Thru-wall access ports, located on the right and left sides of the

chamber, make it possible to add probes, sensors, etc. without altering
the cabinet.

• Interior and exterior accessory receptacles provide a convenient

power source.

– Interior GFCI duplex receptacle on the 115V 3960 unit (Single

European 230V CEE 7 on 3961) 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
Forma accessories.
