APAshton Pumpmatic, Inc. · Model 101
A device designed for the manual withdrawal, transfer, and injection of small volumes of fluid materials. It is made of glass or plastic and is designed as a long thin tube, typically with graduations along its length. The user will typically attach a mouthpiece and create a partial vacuum within the pipette by gently sucking the air from inside the tube inducing the liquid to enter the pipette, or achieve the same action with a squeezable bulb. Closing the mouthpiece or the user end of the pipette will hold the liquid therein; dispensing is done by controlled venting of air into the user end or squeezing the bulb.
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Symptoms: Little or no vacuum at the patient tubing.
Root cause: Low or interrupted tap-water supply / pressure, a worn or scaled venturi (ejector) nozzle, or a blocked hydrophobic filter.
Symptoms: Water backs into the canister or out of the drain, overflow.
Root cause: Blocked drain line or a fouled venturi.
Symptoms: Regulator knob has no effect on the reading.
Root cause: Worn vacuum regulator.
Symptoms: Vacuum will not hold, hiss at the lid or connectors.
Root cause: Worn canister lid seal or quick-connect couplings.
