Horizontal Laminar Airflow System Assures Temperature Uniformity
Thermo Scientific's Forma Environmental Chambers feature a directed airflow system designed to optimize temperature uniformity compared to a conventional top-down airflow system. By directing airflow across the surface of each shelf, samples receive a consistent flow of conditioned air that improves testing accuracy, especially following the door-opening and recovery events. Using positive feed plenums on one side of the chamber and negative pressure return plenums on the opposite side, the horizontal laminar flow system prevents airflow obstruction due to large volumes of samples and their arrangement on the shelves.Customizable to Fit Any Industrial, Pharmaceutical or Biotechnological Application
The Thermo Scientific Forma Series Environmental Chamber offers a wide range of options including condensate evaporators, heatless dryer systems, custom access ports, and additional electrical outlets. Factory-installed shaker support and integrated cell roller systems are also available as custom orders.
