Maintaining air needles 3-9
The air needle lowers deeply into 10-mL vials. When the vials are less than
60% full, the pressurize vial feature is available. The same is true of deep
wells.
Tip:
When deviating from standard settings, use an optional needle type.
Recommendation:
Do not use needle pressurization for low well plates.
The sample needle punctures the seal to prevent vacuum; the function of
the air needle in such a case is insignificant.
