Pass-through chambers streamline workflow by acting as a short-cut for transferring temperature-sensitive samples or materials between rooms of different cleanliness ratings. By having a refrigerated chamber, gone are the days of donning a bunny suit and packing materials in an ice chest to transport items. The High-Capacity Pass-Through Refrigerator from Terra is designed for cleanrooms or controlled labs such as those found in USP-regulated compounding pharmacies. 

Forced air helps maintain temperature uniformity and achieve fast recovery times after doors are opened. Drawer and shelf design also contribute to climate consistency; two-way drawers have a mid-stop point to keep them properly positioned, while adjustable wire shelves present a minimal barrier to air flow. With insulated walls and double-paned glass doors, programmed temperature is maintained to within +/- 1°C.  Users enter the desired temperature (ranging from 2°C-10°C [25.6°F-50°F]) by using the seven-inch color touchscreen.

Seven-inch-wide color touch-screen monitor with icon-based software. When refrigerator is installed, controller is located on the "dirty" side of the wall.
Electromagnetic Interlock ensures that both doors don't open at the same time, preventing cross-contamination of the
cleanroom or lab.
The eye-level touchscreen controller is located on the "dirty" side of the cleanroom for convenient visibility and access. Software is icon-based for fast operation. Features of the system help labs with quality control and auditing requirements:
