Asbestos has so many attractive properties and has often been used in a variety of forms for construction. If building materials are not properly maintained, asbestos fibres can become airborne creating significant environmental health problems. Proper sampling is key to asbestos measurement and determining airborne asbestos concentrations. Sampling methods are also available to determine asbestos concentrations in settled dust. The…
Ideal for gravimetric sampling, collection of organic/inorganic precipitates, and AA (Atomic absoprtion) and HPLC (High-Performance Liquid Chromatography) methods requiring an ashless filter 100% pure, ashless type 40 quantitative cellulose fibre Autoclavable Diameter (mm) Support Pad included † Notes Pack Size Part Number 37 No Cellulose, ashless, equivalent to Whatman Type 40 500 225-18A † Filter supports available
The Diesel Particulate Matter (DPM) Cyclone has been specially designed with an extended retaining ring and special sealing to securely hold the SKC DPM cassettes. Small and lightweight, it is constructed from conductive plastic to prevent the buildup of electrostatic effects. It operates at 2 L/min with a DPM cassette and includes a grit pot, retaining ring and a clip for…
Ideal for maintaining the viability of collected microorganisms, the Gelatin Filters provide unequalled bacteria retention levels for quantitative analysis. The high moisture content helps to maintain microorganism viability for sampling periods up to 30 minutes. The filters dissolve easily when placed on agar, allowing for a gentle transition from sample medium to growth medium. For maximum culturability and superior collection…
GLA-5000 PVC Membrane Filters are suitable for sampling silica, metals, and dust. Suitable for multiple NIOSH/OSHA/ASTM air sampling methods Silica, metals, dust Meets OSHA Method ID-215 (V. 2) for hexavalent chromium Low tare weight and moisture pickup for gravimetric stability <0.5% after 24 hours at 48 %RH and 50°C (122°F) Preloaded 25 and 37 mm cassettes available 25 mm cassettes are convenient for…
Glass fibre depth filters are used where high flow rate and micron/submicron filtration is required. They are suitable for both air and liquid filtration. Select from binder-free filters for purity that is ideal for anaylitcal and gravimetric determination, or filters with binder for strength in long-duration, high-pressure or wet applications. High-temperature tolerance Autoclavable Liquid nominal pore size of 1.0 µm High…
Suitable for most isocyanates, the patented‡ ISO-CHEK sampling system uses a two-stage filter that results in the simultaneous collection and separation of vapour from aerosol at the point of collection.
The standard filter for most aerosol sampling in industrial hygiene applications, mixed cellulose ester (MCE or MEC) membrane filters are comprised of pure, biologically inert mixtures of cellulose acetate and cellulose nitrate. MCE membranes are naturally low in metal background and are compatible with dilute bases and acids and aromatic and aliphatic hydrocarbons. MCE filters are hydrophilic and autoclavable. Meet…
Polycarbonate Membrane Filters are ideal for microscopy. Smooth surface for superior particle capture Thin, transparent, and non-staining Ideal for light and electron microscopy Exceptional background for sample observations Superior chemical resistance, thermal stability, and strength Naturally hydrophobic Exceptionally low tare weight Biologically inert Maximum operating temperature is 140°C (284°F)
The PTFE filters are: Strong and resistant to acids, bases, and solvents Hydrophobic Low background, interference-free chemical determinations Low tare mass for accurate gravimetric analysis Temperature resistant to 260°C (500°F) — autoclavable Ideal for aerosol sampling, especially in environments also containing water vapour 13 mm filter meets NIOSH Method 5517 specifications PTFE filters are the versatile choice for size-selective samplers. The…
Quartz depth filters are used for sampling for elemental/organic carbon, Diesel Particulate Matter (DPM) and trace-level contaminants. Heat treated to reduce trace organics Binder free for maximum purity Low metal background Will withstand temperatures up to 1000°C (1832°F)
SKC silver membrane filters are made of 99.97% pure metallic silver in a controlled environment. The many desirable properties of silver membranes make them suitable for a wide range of applications. Silver Membrane Filter Applications Collection and analysis of coke oven emissions Collection and analysis of polyaromatic hydrocarbons Analysis of airborne silica Collection and analysis of airborne asbestos fibres by…
