Function
The Büchi Vac V-500 is a vacuum pump suitable for evacuating
laboratory equipment to a vacuum of <10 mbar. This is done
with a PTFE diaphragm pump. The pump can be used as an
individual device to create a vacuum and can be expanded to
a complete vacuum system by means of the optional
accessories such as secondary condenser and vacuum
controllers (V-501/502/503).
In the following pages, reference will often be made to pump
inlet and pump outlet.
This distinction is important and can be recognized on the
valve heads as follows. Arrows on both valve heads show the
direction of the gas flow.
The pump inlet
, is at the beginning of the arrow, the tip of
the arrow is the pump outlet
.
Never turn the valve heads so that the arrows point to one
another!
