Fill a 10 mL syringe* (male luer) with water.
2. By using a 3-way connector, attach the calibrated syringe pressure gauge
(must measure up to 30 psi, 2.1 bar, 210 kPa), syringe, and the external
connector of the Acro 50 vent filter.
3. Gently fill the housing and connectors with water.
4. Apply appropriate pressure with syringe plunger and hold this pressure for 15
seconds.
5. Integrity of housing and membrane is proven by retention of water in the syringe,
and by the pressure remaining steady.
6. If failure occurs, check connectors for leaks and repeat above steps. If failure
reoccurs, discard filter unit.
7. After completing test procedure, aspirate the water back into the syringe by
pulling back on the syringe plunger. Disconnect the test equipment. Shaking the
Acro 50 vent filter by hand will aid in further removing residual water in the
plastic housing.
