Pressure Feeding System with Flask

Applicable for VAR B, D (classic, continuous, Gen. II, Professional), J1, J30, W1, V1 (multi nozzle head)

The pressure feeding system consists of:

  1. Pressure reducing station.
  2. Flask 250ml with three nozzles on the head: one for vent, one for transfer with a tip tube and one for filling.
  3. Stainless steel safety basket for protection if flask bursts.


1. Pressure reducing station see flyer "Pressure Reducing Station with Manometer".

Transfer / filling nozzle
3. Safety basket

When working with pressure a safety basket made of stainless steel 1.4301 is of advantage. If the glass has a crevice or if the pressure is too high (it can for example happen if it is connected to the wrong pressure or if the pressure reducing station is defective), the glass can burst. In order to protect the operator and the other staff in the lab always put the flask into the basket when working under pressure.
