-25℃ Combined Refrigerator and Freezer 300L (CAT#: STEM-LT-0511-ZJF)

The BRF-25V Series combines refrigeration and low-temperature freezing in one integrated unit, providing versatile cold storage for biological and chemical materials. Each model features independent temperature zones, microprocessor control, and fast temperature recovery. With capacities ranging from 300L to 450L, these units are ideal for laboratories requiring compact yet reliable dual-function refrigeration. Safety alarms, dual compressors, and optional data logging accessories enhance usability and sample security.
