For more than 45 years we have been producing "Quality Built on Tradition" here in Germany. Our products are renowned for their practicality and attention to detail, continuous technical development and state of the art materials, performance and design. GFL laboratory products are used in more than 150 countries worldwide - a fact that we and our staff are proud of.

The Certification according to DIN EN ISO 9001:2008 secures the high quality standard of GFL laboratory products all over the world.

All GFL Water Stills work economical due to the distillation of heated cooling water, they are reliable, maintenance-free, easy to operate and to service and bear the CE mark. The built-in storage tank accepts twice the hourly capacity of the unit

Specifications and features :

Water Still for single distillation (fully automatic) with storage tank, suitable for both bench and wall mounting.

Very good distillate quality; conductivity approx. 2.3 µs / cm at 25 °C (see "Technical Details").

The distillate storage tank accepts twice the hourly capacity of the still.

Electronic level switch switches the still off when the storage tank is full and restarts it automatically when distillate is withdrawn.

Electronic impurity detector switches the unit off in case of high degree impurities of the water in the evaporator, the red pilot lamp "Clean" will glow.

Thermostatic low water cut-off.

Economical energy consumption by distillation of the heated cooling water.

Water saving through automatic water cut-off. Unnecessary water consumption will be avoided.

Evaporator easily accessible for cleaning purposes .

Condenser (cooling coil) inside the storage tank, easily exchangeable.

Distillate withdrawal through drain cock with continuous and touch position.

CO₂ degassing through outlet in the condenser.

Heating element, evaporator, storage tank and condenser made of stainless steel.

Double-walled housing. Outer housing made of electrolytically galvanised sheet steel, electrostatically powder-coated with epoxy resin.

Water supply through a built-in solenoid valve with connection for pressure hose 1/2" (inner ø approx. 12.7 mm).

Cooling water outlet with hose connection 3/4" (ø approx. 19.0 mm).

Hoses for water in- and outlet are available as accessory.

Applications :

GFL Water Stills are used in research and development e. g. for preparing bacteriological and medical samples, for cell and tissue cultures as well as for the production of reagents and unguents. Moreover, distillate is used for cleaning and sterilisation processes, for buffered solutions as well as microbiological and analytical applications

* Value averaged by Institut Fresenius for operation with tap water. The distillate quality depends on the quality of raw water.
