Gfl Water Still - Single & Double Distilation 2302

Specifications and features          

  • Glass Water Still (fully automatic) for double distillation, suitable for both bench and wall mounting.  
  • Very good distillate quality; conductivity:
  • single distillate: approx. 2.2 µs/cm at 25 °C
  • double distillate: approx. 1.6 µs/cm at 25 °C (see "Technical Details").  
  • Electronic level control during the whole distilling process.  
  • Electronic impurity detector effects rinsing and cleaning of the evaporator by automatic water change.  
  • Water level control in the boiler automatically switches off the power in case of water shortage.  
  • Economical energy consumption by distillation of the heated cooling water.  
  • Water saving through automatic water cut-off. Unnecessary water consumption will be avoided.  
  • Sterillisation of the condensers by steam.  
  • Visible distillation process due to the easily removable, unbreakable front screen which does not steam up.  
  • Quartz sheated heating elements.  
  • Evaporator, condenser and overflow are made of borosilicate glass. Condenser with dribble guard.  
  • Distillate withdrawal through hose connection at the right-hand site.  
  • CO2 degassing through outlet in the condenser.  
  • 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 1/2 inch (inner- ø approx. 12.7 mm).  
  • Hoses for water in- and outlet are available as accessory. 

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 and HPLC, too.
