OSHA Versatile Sampler (OVS) Tubes
OSHA Versatile Sampler Tubes The tubes combine sorbent and filter in one tube; a filter to trap aerosols and a two-section sorbent bed to adsorb vapours.
The tubes combine sorbent and filter in one tube; a filter to trap aerosols and a two-section sorbent bed to adsorb vapours in one specially constructed glass tube that eliminates filter and tube sampling trains. Aerosols and vapours can be collected simultaneously. Ideal for sampling pesticides, explosives and glycols. Only cleaned and verified materials are used in OVS tubes to ensure low background interference. A flow rate of 1 L/min is typically used, and the samples are solvent extracted and analysed by gas chromatography (GC) or high performance liquid chromatography (HPLC) with detector.
- Sorbent and filter combined in one tube for NIOSH and OSHA
- Collect vapors and aerosols simultaneously
- Available with a variety of sorbents for special uses
- Low backgrounds ensure sample integrity
- Meet OSHA and NIOSH design specifications
For mixed-phase sampling using a true inhalable sampler that meets ISO 7708/CEN, see the IFV Pro Sampler.
The size of all the OVS tubes is 13→8 x 75 mm (Length x OD) and the tubes have open glass ends. The OVS Tube Holder (224-29V) is designed to accommodate the 13 mm diameter of SKC OVS tubes, provide a convenient clip to attach the tube in the breathing zone, and protect the tube during sampling.
Note: All OVS tubes have limited shelf-life; refrigerator/freezer storage may be required. Contact SKC for more information.
To select a tube for a specific compound refer to the SKC Sampling Guides.
