Flow-Limiting Orifices, Creates Quantitative Airflow Through A Filter For Airborne Contamination Analysis, Each

Details:

Flow limiting orifices create quantitative airflow through a mf-millipore filter for airborne contamination analysis. The orifices are threaded into the outlet of a millipore aerosol analysis holder or aerosol adapter to enable a constant flow rate when required vacuum level is applied.Ratings are accurate to within approximately 15%. For greater precision, calibrate orifice with a flowmeter at actual working vacuum level.
