Laboratory freezer BDF-40H SERIES

for sample storagemedicalupright

Introduction
Ultra-low temperature freezer with two independent compartments. Designed to store different types of samples that require separate temperature control or segregated storage. Independent control for each chamber helps optimize space and energy use.
