tomated machines that prepare, manage,
and analyze laboratory samples.
Handheld Electronic Pipettes
Before analyzing a sample, a lab technician
must complete a long list of procedures
that may include dissolution,
extraction, reaction with some chemical
species, pulverizing, treatment with a
chelating agent, masking, filtering, dilution,
and subsampling. Handheld pipettes
are used to transfer liquid samples

from one test receptacle to another
during preparation.
Pipettes typically consist of a system
of cams, pistons, and cylinders. When
the piston is moved, a partial vacuum is
created, and the liquid is drawn into the
pipette tip. Pipettes come in a variety of
sizes, with volumes ranging from a few
microliters to a few hundred milliliters.
Prior to each manipulation, the user
must clip on a brand-new tip to ensure
that cross-contamination does not oc19
