BrandTech Scientific Transferpette S -8/-12 - Manual (Page 32)

32
The instrument 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)
Limitations of Use
The pipette is an air-displacement system for pipetting aqueous solutions
with medium density and viscosity.
Purpose
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 ± 1 °C /± 1.8 °F.
Operating Limitations
The user has to ensure the compatibility of the instrument with the
intended application.
This instrument cannot be used:
• for liquids incompatible with polypropylene and FKM
• for liquids attacking polycarbonate (viewing window)
• for liquids attacking polyphenyl sulfide
(50 µl, 100 µl, 200 µl and 300 µl models)
• for liquids of a very high vapor pressure
