VWR pipettors operate using an air-cushion
(i.e., the aspirated liquid does not come into contact
with the shaft or plunger of the pipettor). The liquid is
drawn into the disposable tip attached to the pipettor.
2. Packing
The pipettors are delivered with the following:
Description
Instruction manual
Quality Control certificate
Calibration key
Pipettor hanger
Identification labels
Lubricant (for single-channel pipettor)
Ejector cap
(for pipettor models 2, 5, 10, 5,000, and 10,000 μL)
Filters (for pipettor models 5,000 μL and 10,000 μL)
Ejector spacers (for models up to 1,000 µL)
Filters
The 5,000 μL and 10,000 μL pipettors include a replace-
able filter, fitted at the bottom of the shaft which
prevents aspirated liquid from entering the shaft and
contaminating the inner surface and plunger. Use of
the filter is particularly important when aspirating and
dispensing large volumes of liquid. The filter should be
replaced if it becomes wet.
