IMPORTANT NOTICE: SKC Plastic Cyclone Notice
A recent study performed by the UK's Health and Safety Laboratory (HSL) indicates that the performance of the SKC Ltd Plastic Higgins-Dewell-style Cyclone (Cat No. 225-69, all models) operated at 3.0 L/min conforms to the BS EN 481, which is the same as the ISO/CEN convention. The cyclone oversamples relative to the criteria at the originally specified flow rate of 2.2 L/min.
SKC recommends that customers now use the SKC plastic cyclone at a sampling flow rate of 3.0 L/min. It is worth noting that at 3.0 L/min the total volume collected over an 8-hour period would be 36% higher than at 2.2 L/min, therefore giving a lower limit of detection.
Important to also note that the SKC Aluminium and GS cyclones, commonly used in the U.S. are NOT affected; continue to use them as specified.
