The MTST DW-86L30 is a 30-liter upright ultra-low temperature freezer with an operating range down to -86°C. Its small footprint suits labs that need ultra-cold storage without dedicating large floor space to a full-size unit.

The freezer is intended for storing reference standards, biological samples, and small quantities of fresh-frozen plant material that require sustained low temperatures. It uses a cascade compressor system paired with digital temperature control and an integrated alarm.

This unit is a fit for extraction and processing labs, research benches, and sample archives where consistent ultra-cold conditions are required in a compact format.

How It Works

The unit uses a cascade refrigeration system, which links two compressor stages to reach temperatures well below what a single-stage system can achieve. A digital controller regulates the setpoint within the -40°C to -86°C range, and an alarm system signals out-of-range conditions.
