- Is a continuous light air bleed normal with the Pressure Injectosr?
A light air bleed is normal. The precision pressure regulators in our injectors continuously bleed a small amount of air to operate correctly. However, if the air leak is loud and heavy, or varies with regulator adjustments, then a worn out regulator is implied.
- Is there an advantage to using an acrylic pipette holder instead of the stainless steel pipette holder included in the PLI-90 Plus package?

This is likely due to the hold vacuum being set too high. In general, the hold pressure regulator controls both the hold vacuum as well as the clear-hold pressure. The higher the holding vacuum, the higher clear-hold pressure will be. Press the CLRH button to push the cell out of the holding pip ...
