-40℃ Combined Refrigerator and Freezer 318L (CAT#: STEM-LT-0524-ZJF)

The BRF-40V series is a two-room low-temperature refrigeration solution combining a 2-8℃ refrigerator and a -40℃ freezer. Each chamber is independently controlled, enabling energy-efficient storage of diverse sample types. These units feature microprocessor-based control, dual compressors, stainless steel interiors, and reliable cooling systems. Available in 318L, 368L, and 450L capacities, the series is ideal for laboratories and institutions seeking compact, multifunctional cold storage.
