The MTST DW-86L105 is an upright ultra-low temperature laboratory freezer with a 105-liter capacity. It operates across a temperature range of -40°C to -86°C, supporting demanding cold-storage requirements such as biological samples, reference standards, and fresh-frozen cannabis biomass.

The interior is constructed from SUS304 stainless steel, and the cabinet uses 105 mm to 120 mm of insulation to maintain stable internal temperatures. A side-opening foam door with an available lock helps secure stored material.

This unit is intended for extraction and processing labs that need reliable low-temperature sample storage with organized, shelf-based access.

How It Works

A cascade compressor refrigeration system drives the unit down to ultra-low temperatures. Cooling is delivered through a wall-mounted copper tube evaporator, while an aluminum finned copper tube condenser dissipates heat. A digital controller manages the set point and triggers over-temperature and sensor failure alarms.
