The ZZKD 50L ultra-low temperature freezer provides adjustable cold storage across a -40°C to -86°C range. With a 50-liter capacity and a top-opening foamed door, it suits labs that need reliable ultra-cold storage in a compact footprint.
The interior is constructed from SUS 304 stainless steel and surrounded by 100 mm insulation. Four casters allow the unit to be repositioned within a workspace. It is intended for storage of fresh-frozen biomass, extract archives, and sample preservation.
This model offers greater capacity than the 28L version, making it a fit for growing labs that require additional ultra-cold storage volume.
The freezer uses a cascade compressor system with digital temperature control to reach and hold ultra-low temperatures down to -86°C, with the setpoint adjustable across the rated range.
