Solvent Dispensing System
The miniPV Series is equipped with a solvent system used to wash the
viscometer tubes after each sample test. The system consists of the
internal and external solvent and drain lines, the user-supplied solvent
vessel, and the Waste Receiver assembly (including solvent dispensing
unit). Appropriate solvent containers may be acquired from many suppli-
ers, including JustRite
®
and Nalgene
®
(see weblinks below).

Maintaining the solvent system
The miniPV Series requires solvent, which is used to wash the viscom-
eter tube and rinse the sample vial after each sample analysis. The
solvent system consists of the solvent containers, the solvent distribution
and drain lines, and the Waste Receiver.
The user-supplied solvent container(s) provide the solvent necessary to
clean the viscometer tubes before and after samples are tested. The
solvent delivery lines distribute solvent to the viscometer tube(s). The
drain lines collect the waste sample/solvent from the viscometer tubes,
and transfer waste materials from the washing station to the Waste
Receiver.
Solvents
The miniPV Series is compatible with aqueous and hydrocarbon-based
(heptane, hexane, toluene and acetone) solvents. Please contact CAN-
NON Instrument Company with any questions regarding solvent compat-
ibility with instrument components. The supplied Waste Receiver is
polypropylene. This material should be suitable for solvents/samples
compatible with the miniPV Series.
CAUTION
When configured for dual solvent operation, the miniPV Series is capable
of using both a washing and a drying solvent for certain applications. The
solvents are selected by the user. Ensure compatibility of dual solvents at
all times. If switching from one solvent to another with potential compatibil-
ity problems, make certain to empty the Waste Receiver and flush the
solvent lines several times with a neutral solvent. CANNON

WARNING
Selection, handling and disposal of solvents are the responsibility of the
user. CANNON

Instrument Company does not make specific solvent
recommendations. Refer to the Material Safety Data Sheet (MSDS)
provided with the solvent material, and exercise the necessary safety
precautions. Use extreme care when working with hazardous solvents.
