Filter Holders, Monitors for Air Monitoring

Aerosol Filter Holders

For environmental monitoring

These aerosol filter holders are designed for monitoring airborne particulates from the environment and/or closed systems. Choose the holder design most appropriate for your method. Aerosol filter holders are available in two formats: open-type for open atmosphere sampling and a standard design with a closed connection and inlet dispersion chamber.

Applications 

• Particulate Contamination Monitoring in Gases

• Ordering Information and Associated Products

PVC Membrane Filters

Pure, Medical grade PVC for sensitive air monitoring

Polyvinylidene chloride (PVC) membranes are specified by ASTM, NIOSH, and OSHA in air monitoring applications to analyze silica, carbon black, metals, quartz particulates and others.

Features & Benefits

· High-quality, medical grade PVC polymer

· PVC is non-hygroscopic, so humidity will not impact your gravimetric analysis

Applications

Air Monitoring of Particulate Contaminants Including Silica, Metals, and Quartz

PVC Membrane Filters

• PVC502500 | 5 µm- 25 mm- White- Plain- 100/Pack

• PVC503700 | 5 µm- 37 mm- White- Plain- 100/Pack

Silver Membrane Filters

Pure silver filters for particulate monitoring

Silver membrane filters are suitable for a variety of applications and are commonly used for air monitoring and analysis of particulate contaminants. Methods from standards organizations like NIOSH specify silver membrane filters for collection and detection of particles such as silica, carbon black, coal tar products, and coke oven emissions.

Features & Benefits

• · Pure silver

• · Highly resistant to thermal stress and aggressive chemicals

• · Low background for sensitive X-ray diffraction analysis

Applications

Air Monitoring: Asbestos, Lead Sulfide, Crystalline and Amorphous Silica

Silver Membrane Filters

• AG4502550 | 0.45 µm- 25 mm- Plain-50/Pack

• AG800375 | 0.8 µm- 37 mm- Plain-50/Pack

Aerosol Contamination Monitors

With 25 mm and 37 mm filters

Two types of three-piece aerosol contamination monitors are offered: the PS monitor (Type A) and the PP monitor (Type B). Type A is a clear, polystyrene monitor with a 16 mm center ring. The three-piece design holds the filter in place when the top section is removed for open aerosol sampling. Monitors are available in 25 mm and 37 mm diameters, with female Luer-Slip™ vacuum connection. Type A monitors are also available without membrane. Type B is a three-piece carbon-filled polypropylene conductive monitor with 50 mm extension cowl. Barbed hose vacuum connection eliminates the need for tubing adapter. Use monitors (Cat. No. MAWP025AC) for airborne asbestos monitoring in accordance with NIOSH specification

Features & Benefits

• · Compliant with NIOSH standard methods

• · Boxes marked with Average Background Count (ABC) values

• · Pre-assembled with in place

• · Available with white, black or gridded membranes in two pore sizes

• · Available with matched-weight membranes to save time during gravimetric analysis

• · A thin cellulose support seals the filter between monitor sections to distribute sample flow evenly over the filter surface

Aerosol Analysis Accessories

For environmental monitoring

The Aerosol Adapter adapts your vacuum source to an aerosol analysis monitor, Swinnex 47 mm filter holder or other products with female Luer inlets. Attach a flow-limiting orifice for quantitative aerosol sampling. The adapter’s vacuum-hose end fits the hole of a No. 8 sile stopper, (cat. no. XX1004708) and the opposite male Luer-Slip™ end fits Swinnex filter holders or monitor outlet connections. Flow-limiting orifices create quantitative airflow through an MF-Millipore™ filter for airborne contamination analysis. Thread the orifice into the outlet of an aerosol analysis holder or aerosol adapter for a constant flow rate

Features & Benefits

• · Modulate flow rate to meet specified flow rates without the need for additional flow regulators or valves

• · Flow-limiting orifice ratings are accurate to within approximately 15%; for greater precision, calibrate orifice with a flow meter at actual working vacuum level

Applications

Air Monitoring, Environmental Monitoring, Aerosol Contamination Monitoring
