Functions And Limitations Of Use; Operating Exclusions - BRAND Transferpette-8 Instrucciones De Manejo

The Transferpette -8/-12 electronic is a micropro-
®
cessor-controlled, battery-operated piston-stroke
multichannel pipette which uses the air-displace-
ment principle for the pipetting of aqueous solu-
tions with an average density and viscosity.
Limitations of use
The Transferpette electronic is intended for the
®
pipetting of liquids within the following limitations:
– Temperature of both the instrument and solution
should be between 15 °C to 40 °C (59 °F to
104 °F). Consult the manufacturer for use in
temperatures outside of this range.
– Vapor pressure up to 500 mbar
– Viscosity: 260 mPa s (260 cps)

Operating exclusions

The user has to ensure the compatibility of the
instrument with the intended application.
Never use the instrument for pipetting liquids,
that react adversely with polypropylene (PP: shaft
and tips), polycarbonate/polybutyleneterephthalate
(PC/PBT: casing) or EPDM (flexible replacement
pipette shafts). Avoid reactive vapors due to the
danger of corrosion.
The handle is not autoclavable.

Functions and Limitations of Use

When the instrument is used properly, the sample
only comes into contact with the tips and not with
the Transferpette
Operating Limitations
Viscous and highly adhesive liquids may impair
volumetric accuracy. Volumetric accuracy may also
be impaired when pipetting liquids that differ from
ambient temperature by more than ± 5 °C / 41 °F.
