Pressure-Feeding System with Flask
Applicable for VARD2Go, VARJ30, VARV1, J1, W1

The pressure feeding system consists of:

1. Pressure reducing station.
2. Flask 100ml 250ml , 500ml or 1000ml 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.

Blind nozzle:	Hose material:	silicone for refilling during the process.
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.
3. Flask with cover for large flowrate
Cover with hose connector ID 3mm which allows to feed nozzles with diameter >1mm or the multi nozzle heads. 1000ml Flask, ID 3mm hose connector Connection Feed Tip Tube with hose connector Optional - Luer-Lock adapter connectors, 2mm for hose Connection air hose connector The adapters for small hoses and blinds are also available for the cover.
