The Plasma Freezer provides an optimal extremely cold temperature for plasma and test samples conservation. The instrument’s exterior body is composed of heavy
gauge hardened steel that has been powder coated, and the inner chamber is built of stainless steel (304). This unit is designed to maintain a stable and uniform
temperature of up to -40.0°C in both vertical and horizontal configurations, and comes in four different sizes. A built-in stainless steel insulated inner door is
included in the user-friendly design, and simple calibration is accessible via the control panel. This, combined with a visual and audible alert system, guarantees that
your samples are not only safe but also accessible when you need them.
