Limitations of Use

Purpose
The pipette is an air-displacement system for pipetting aqueous solutions
with medium density and viscosity.
Limitations of Use
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)
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 ± 1 °C /± 1.8 °F.
Operating Exclusions
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 polyvinylidene fluoride and silicone
• for liquids attacking polyphenyl sulfide
(50 µl, 100 µl, 200 µl and 300 µl models)
• for liquids of a very high vapor pressure
