Millipore® Aerosol Analysis Air Flow-Limiting Orifices

These Millipore flow limiting orifice devices create quantitative airflow through any Millipore membrane filter for airborne contamination analysis. The flow limiting orifice device is threaded into the outlet of a Millipore Aerosol Analysis Monitor Filter Holder or Aerosol Adapter. Air flow remains at a constant rate when required vacuum level is applied. Ratings are accurate to within approximately 15%. For greater precision, calibrate the orifice with a flowmeter at the actual working vacuum level.
