28 Cu. Ft. Standard Solid Door Laboratory Refrigerator

Product Number: ABT-NA-SLS-28 ★ NEW PRODUCT

ALSO AVAILABLE IN THESE SIZES12 16 23 36 49 72 CU. FT.

This 28 Cu. Ft. laboratory refrigerator delivers precise cooling for sensitive research materials. Forced-air circulation evenly distributes cool air throughout the cabinet, helping maintain stable temperatures and protect valuable samples. The self-closing solid door minimizes temperature fluctuations while shielding light-sensitive materials from ambient light exposure. For added security, this model features multiple built-in alarms and a keyed door lock. Additionally, the natural hydrocarbon refrigerant provides environmentally sustainable, energy-efficient cooling. Together, these features make this refrigerator an ideal solution for clinical, research, and laboratory environments.
