The Labmart LMFD160E Mini Freeze Dryer is a compact freeze-drying system designed for small-scale experimental and laboratory applications. It operates with a –60°C condenser, 4.3-inch touchscreen display, 4-manifold valve, high-precision vacuum gauge and a standard double-stage oil-lubricated rotary vane vacuum pump. The system includes four 250 mL flasks and provides an ice-condenser capacity of 1–1.8 L/24h.

Product Overview

The Labmart LMFD160E Mini Freeze Dryer is a compact laboratory freeze-drying system designed to remove water from frozen materials through sublimation, where ice is converted directly into vapour without passing through the liquid state.

The freeze-drying process combines controlled heating to vaporize ice, vacuum to remove the resulting vapour and a cold collector to condense the vapour back into ice. The LMFD160E incorporates a single-cascade refrigeration system with a condenser temperature of –60°C.

The system features a 4.3-inch touchscreen, high-precision vacuum gauge and a tree-type 4-manifold valve. Four 250 mL flasks can be connected for small-scale processing. A DSVP57 double-stage oil-lubricated rotary vane vacuum pump is supplied as standard.

The supplied catalogue identifies the LMFD160E as suitable for small-scale experimental use and emphasizes its compact design and easy handling.
