Additional Information

Sliding the filling lever too quickly can cause excessive
vacuum. This can cause tiny air bubbles to accumulate in
the liquid which may lead to dispensing inaccuracies.
Important: The first dispensing step must be discarded in
order to release any residual pressure from the dispensing
system after filling and to prepare the system for precise
dispensing. Small bubbles in the TipOne
Tip beneath the piston will not affect dispensing accuracy
since the residual stroke lock prevents the dispensing of
any remaining sample after the last dispense.
It is not necessary to completely fill the TipOne
Dispenser Tip. Partially filling will not cause dispensing
inaccuracies.
