1 - INTRODUCTION
™
The VWR Signature
instrument designed to measure and transfer liquids
precisely and safely. These variable volume pipettors
cover the range from 0.1 μl to 10000 μl in 10 models.
VWR EHP Pipettors are supplied with tip ejector, designated
as "VE" or without a tip ejector, "V".
The VWR EHP Pipettors have a digital counter displaying
the set volume. The set volume is visible in the window
situated in the hand grip of the pipettor. Volume is
adjusted by turning the pipetting pushbutton (Fig. 1A2)
or by turning the adjustment knob [Fig. 1B). The pipette
design allows the user to lock the volume setting by
pushing the locking ring upwards. The position of the
ring is indicated by the symbols located on the handle.
The volume range of the pipettor is shown on the
pushbutton (Fig. 1A1).

The VWR EHP Pipettors use disposable polypropylene tips,
(Fig. 1E). Disposable tips eliminate cross contamination
between samples and ensure maximum user safety. The
tip ejector built in to the VE series protects the user from
contamination when removing the tips.
The VE series features an adjustable, removable tip ejector.
The tip ejector adjusts to accommodate a wide variety of
tips. When pipetting in narrow tubes, it may be necessary
to remove the tip ejector. To remove, grasp the ejector
by the finger grip located near where the ejector attaches
to the body of the pipettor. While pressing down on the
ejector button, pull the ejector down, (Fig. 1D)
Adjusting Tip Ejector Length
- Models VWR VE2 to VWR VE1000 pipettors (Fig. 6A):
The interchangeable "H" spacers provided with the
pipettor allow for adjusting the length of the tip ejector by
+1mm or +2mm. The pipettors are supplied with the H0
spacer in place. To change the spacer, remove the ejector
as described above. Replace the H0 spacer with either
the H1 or H2 spacer. Reverse the removal process to fit
the ejector back in place.
- Model VWR VE5000 and VWR VE10000 pipettors (Fig. 6B):
The length of the tip ejector can be adjusted in the range
of 5 mm. To adjust the ejector, remove the tip ejector
