Laboratory Freeze Dryers

Laboratory Freeze Dryers - LIOALFA 6

The LIOALFA 6 is a general purpose laboratory freeze dryer designed for use in research in biotechnology, clinical and pharmaceutical fields. The equipment is very flexible and can be used for simultaneous freeze drying in flasks, vials or bulk by connection to various manifold systems or to a chamber. The unit is designed and manufactured according to GLP requirements.

General Features:

Compact designed base unit complete with castors for easy mobility, constructed in a steel stove enamelled cabinet with stainless steel front and rear doors for service purposes
Simple connection for the operation systems: chambers, tube manifolds )see accessories)
Two stage vacuum pump, supplied with gas ballast to remove water vapour or other condensibles that could reach the pump. Exhaust filter included.
Air-cooled refrigeration system: hermetically sealed; ozone friendly refrigerant.
Easy viewing of ice formation in condenser through a transparent acrylic door.
Control system by microprocessor with digital screen.
Read-out of vacuum and condenser temperatures.
Adjustment and read-out of shelves and product temperatures (only with chamber as accessory).
