3.2 Purpose
This is an air displacement pipette for pipetting aqueous solutions of
medium density and low to medium viscosity.
3.3 Limitations of use
This instrument is intended for pipetting samples, within the following
limitations:
•
Operating temperature of instrument and reagent should be be-
tween +15 °C and +40 °C (59 °F to 104 °F) (other temperatures
upon request)
•
Vapor pressure up to 500 mbar
•
Viscosity: 260 mPa s
3.4 Operating limitations
Viscous and wetting liquids may compromise volumetric accuracy. Volu-
metric accuracy may also be affected when pipetting liquids whose tem-
perature deviates from the ambient temperature by more than ± 1 °C/
± 1.8 °F.
