The MTST DW-45L30A is a compact benchtop laboratory freezer with a 30 L (1.06 cu ft) effective volume. The DW-45L30A model operates across a temperature range of -15°C to -45°C and is built for low-temperature storage of biological samples, specimens, reagents, and materials.

The unit uses a single-stage refrigeration system with a stainless steel SUS304 interior and a side-opening door. Its small footprint makes it suitable for bench or countertop placement where floor space is limited.

The DW-45L30A is part of a model family that also includes the DW-60L30A (-25 to -65°C) and DW-86L30A (-45 to -86°C); confirm the specific model to match the intended temperature range.

How It Works

The freezer uses a single-stage compressor refrigeration circuit with a copper-tube evaporator for heat exchange. A digital electronic temperature controller regulates the chamber, and the insulated cabinet with a sealed side door helps maintain the set point.
