This vacuum line (shown is the 1 l-model) serves to conduct vacuum between a pump and the reaction vessels. It has three stopcocks for attachment, one connector (no stopcock) to a manometer and stopcock connection to the vacuum pump. The vacuum pump connection is avilable as ball-joint, as tapered ground glass connector or as a glass tube for rubber tube cinnections. For protection of the pump, a cold trap should be placed between the vacuum line and the pump. The vacuum line has a volume of 1 l and may thus be used as a surge vessel for measuring of gases in the volume range used in laboratories.
We offer also manometers for use in gas volume measurement.
We also offer upon inquiry vacuum lines up to a volume of 10 l.

The volumes will vary within a small tolerance and will have to be determined maonometrically before first-time use.
