Functions And Limitations Of Use; Operating Exclusions - BRAND Transferpette-8 electronic Operating Manual

®
The Transferpette -8/-12 electronic is a micro-
processor-controlled, battery-operated piston-
stroke multichannel pipette which uses the air-
displacement principle for the pipetting of aqueous
solutions with an average density and viscosity.
Limitations of use
The Transferpette ® -8/-12 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) for the instrument and the reagent.
Consult the manufacturer for use in tempera-
tures outside of this range.
- Vapor pressure up to 500 mbar
- Viscosity: 260 mPa s (260 cps)

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 exclusions

Never use the instrument for pipetting liquids,
that react adversely with polypropylene (PP: shaft)
or polycarbonate/polybutyleneterephthalate (PC/
PBT: handgrip). Avoid reactive vapors due to the
danger of corrosion.
Do not use use aggressive cleaning agents (e.g.,
bleach) to clean the instrument. Distilled water or
a mild soap solution is recommended.
The pipetting of highly dense or viscous liquids
as well as the pipetting of liquids, which react with
polypropylene (PP) or polycarbonate/polybutylene-
terephthalate (PC/PBT) is only possible within
limitations.
