Key Features & Benefits
This instrument uses an efficient diaphragm pump whose flow rate is precisely maintained using automatic flow control circuitry (Patent pending). The pump draws contaminated air through a sampling head at a rate determined by the head design or sampling strategy.
The Apex was developed to provide sampling capabilities between 5 ml/min and 5 l/min (4 l/min for I.S.versions), suitable for a wide range of applications including solvent fumes, asbestos clearance and personal sampling of dusts. Apex pumps are ideally suited to many of the “Total” and “Respirable” dust sampling techniques detailed in the U.K. Health and Safety Executive’s publication MDHS14, and in other reference methods.
The applications in this instrument include:
Pump Manager is a versatile software package simplifying the management and reporting of sampling data.
In order to undertake personal monitoring with sampling pumps, specific sampling heads and media must be used in accordance with regional or national sampling methodologies. A comprehensive range of sampling heads, adsorption tubes cassettes and sampling media tubes often specially treated filters or collection devices are utilized.
Paper or other material filters are used for collection of dusts, fumes and mists, whilst silica or charcoal tubes are used to collect vapours. By reference to local or national sampling methodologies selection of the correct media can be made.
