Section 1
Introduction
Th
e MASTERFLEX® L/S® Portable Sampler Pump Drive provides pump speeds
from 70 to 400 rpm in a clockwise or counterclockwise direction for purging the
tubing and for the sampling of liquids.
Th
e Drive and charging system are current limited, protected from reverse power
supply polarity and transient voltages.
You may operate the Drive on the internal battery, an external 12V DC source
or 115 V AC or 230V AC when used with the AC/DC Power Supply/Converter
supplied with the unit.
Th
e Drive has a built-in spill-proof battery and recharging system allowing the
unit to be recharged from an AC power source using the supplied AC/DC Power
Supply/Converter or from an automotive 12V DC electrical system if used with
the Automotive Power Adapter accessory.
It is designed to accept and power one MASTERFLEX® L/S® Standard, QUICK
LOAD®, EASY-LOAD® or PTFE Tubing Pump Head for fl uid transfer and
sampling in the fi eld.
Th
e unit is housed in a high visibility, protective housing. Th
e control panel
and the drive controls are protection rated to IP54 only when a Pump Head is
mounted on the drive.
When closed, the drive will fl oat for a minimum of 30 minutes if dropped into a
lake or stream to allow recovery of the unit.

Suction Lift
Th
e combination of the MASTERFLEX® L/S® drive and a single MASTERFLEX
Pump Head is capable of lift ing a sample of water up to twenty-six (26) feet
vertically. Th
is capability is called suction lift and is measured from the surface
of the liquid to the Pump Head.
If the liquid to be sampled has a viscosity or density greater than that of water,
this lift ing capability is reduced or diminished.
