9 GUIDELINES FOR GOOD PIPETTING
Aspirate and dispense
• They form an air-tight seal with the tip-holder,
preventing the leaks that cause poor accuracy and
a lack of precision.
• PIPETMANTIPS (except lter tips) may be auto-
clavedat121°Cfor20minutesat0.1MPa.
Do not autoclave PIPETMAN Filter Tips, they
have been sterilized!
To ensure the best performance from
your Gilson pipette, you shoud ALWAYS
use PIPETMAN Tips (in accordance with
ISO8655) system, because PIPETMAN Tips
were used to establish the specifications.
