-40℃ Dual-Chamber Laboratory Freezer 368L (CAT#: STEM-LT-0531-ZJF)

The BDF-40V series dual-chamber freezers are engineered to store multiple types of temperature-sensitive materials in one unit while maintaining independent temperature control for each chamber. With a range of -15℃ to -40℃, the freezers feature environmentally friendly R290 refrigerant, high-efficiency insulation, and robust alarm systems. They are ideal for labs requiring flexible and reliable ultra-low temperature storage solutions.
