Installing Hard Tubing
Quick Connect Fitting
Collar1/4 in. Tubing
To insert, push the tubing in firmly.
To remove, push in on the collar
while pulling the tubing out.
Fig. 9— The PicoPump Pressure and Vacuum ports are located on the rear panel.
!
CAUTION: Do not remove tubing holders. These parts are intended to remain on
the pump.
To install the hard tubing, fi rmly insert tubing into the quick-connect fi ttings on the rear of
the instrument. When the tubing is inserted far enough, it engages and cannot be pulled
out. To remove the tubing, press in on the surrounding collar while pulling the tubing out.
Plastic tubing can be disconnected easily, while metal tubing may require more effort. An
example of a common setup is shown in Fig. 10.

PV830
Fig. 10— This diagram show an experimental setup of the PV830. The PV820 setup is
identical.
Vacuum Input–Connect the Vacuum Input (located at the back of the instrument) to
a suitable source of vacuum, such as a vacuum pump (WPI #LM-500865) or aspirator,
using 0.25˝ OD hard tubing and the silicone connector (supplied, Fig. 4). Vacuum may be
anywhere in the range of 0–30 in. Hg. The vacuum line does not need to be connected
when only positive pressure is needed.
