6 World Precision Instruments
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 soft plastic connector (supplied). Vacuum may be
anywhere in the range of 0–30 in. Hg. The vacuum line does not need to be
connected if only positive pressure is needed.
Pressure Input
Connect the Pressure Input (located at the back of the instrument) to a suitable
source of pressure, such as a compressed gas tank or an air line, using 0.25˝ OD
tubing supplied. Pressure may be anywhere in the range of 0–150PSI. Connect this
0.25˝ OD tubing to the quick connect fitting as indicated in Fig. 6.
A 0.25˝ FNPT fitting is supplied for connection to a nitrogen regulator on a N
2
tank. Recommended gases are dry air, nitrogen or argon. Never use corrosive
gases. If an air pressure line containing oil or water vapor is used, an external filter
is recommended to prevent excessive contamination of the internal pneumatic
components.
! WARNING: THE PRECISION REGULATORS USED IN THIS INSTRUMENT
CONTINUOUSLY VENT A SMALL AMOUNT OF SUPPLY PRESSURE AS A
PART OF THEIR NORMAL FUNCTION. TO PREVENT WASTE OF GAS,
ALWAYS TURN OFF THE MAIN SUPPLY PRESSURE WHEN THE PV830 IS NOT IN
USE.
Eject Pressure Port (front panel)
Each PicoPump is supplied with two PicoNozzle Kits plus tubing to connect the
holders to the pressure and vacuum ports. Use one kit for pressure, one for vacuum.
Version 1 Kit (Optional)
Fig. 7—PicoNozzle Version 1 Kit (#5430-xx) allows micropipettes to be securely mounted
in micropositioners for stable axial air delivery. Because air enters the pipette axially,
lateral whipping during injection is eliminated.
