Thermo Scientific Large Capacity CO2 Incubator - TC Sensor
Part Number: 3950
Precision 3950 CO2 Laboratory Incubator
Our full-featured Thermo Scientific Forma Reach-In CO2 Incubator is the reliable reach-in that will meet your application needs today and in the future – without requiring expensive add-on options. This durable unit is ideal for culturing large volumes of patient samples for bacterial growth, performing short-term growth studies, and working with large volume products.
The reach-in provides elevated RH to prevent product desiccation in medium-term cultures, and maintains temperature uniformity even when equipment is installed in the chamber (e.g., cell rollers, rockers, shakers, stirrers, or other lab equipment).
Tight temperature uniformity contributes to an ideal culturing environment, even when the chamber is completely full
Valuable features are included, rather than optional, ensuring cost-effectiveness and ultimate flexibility for a wide range of applications
Swivel, locking casters for mobility come installed
All stainless steel interior for durability
Tight Temperature Uniformity for Ideal Culturing
You can be confident of optimum temperature uniformity and recovery when you put this high capacity chamber to the test with large product loads and low output, heat-generating equipment.
Directed Horizontal Laminar Airflow System promotes an ideal growth environment.
Includes a positive pressure feed plenum on the left side of the chamber and a negative pressure return plenum on the right. 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.
Directed airflow prevents deterioration of temperature uniformity and recovery when shelves are full because airflow is not blocked
The Thermo Scientific Forma Reach-In CO2 Incubator's directed airflow minimizes the risk of product desiccation and loss, and wasted time and money due to poor temperature uniformity and recovery.
Easy to Configure and Use
Intuitive Enviro-Scan controls with easy digital settings in 0.1°C increments
Three-setting humidity RH system - off, medium, high - is easy to use, reliable, and can be customized for your application
Three water fill options - automatic, semi-automatic, and ergonomic manual - accommodate your facility's setup and provide the convenience of a long time period between refills
Enviro-Scan Microprocessor Message Center (shown below) allows you to control all parameters without complicated programming
Valuable Features Included for Cost-Effectiveness and Flexibility
You don't need to purchase a range of expensive options to create a chamber that truly meets your needs. Primary features for ultimate flexibility are already built-in.
Swivel, locking casters ensure easy mobility for installation and cleaning. Leveling feet provide stability for added safety in the lab.
Heated triple-pane glass door minimizes condensation and permits a clear view of your product.
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.
Two thru-wall access ports (one on right and left sidewalls) make it possible to add probes, sensors, power cords, etc. without altering the cabinet.
Interior GFCI duplex receptacle located in the upper right corner of the rear wall, permits the use of cell rollers, rockers, shakers, stirrers, or other lab 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.
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 on 2.0" centers for convenience.
Stainless steel interior is more durable and corrosion resistant than plastic or painted metal, ensuring a long life and minimizing equipment costs.
