Button Sampler Pump Kit

The reusable SKC Button Aerosol Sampler is a filter sampler with a porous curved-surface inlet designed to improve the collection characteristics of inhalable dust (< 100-µm aerodynamic diameter), including bioaerosols for viable or non-viable analysis. The curved, multi-orificed inlet, made of conductive stainless steel, reduces electrostatic effects and reduces sensitivity to wind direction and velocity. The proximity of the filter to the inlet minimizes transmission losses and provides equal distribution of particle loading and low intersample variation. The Button Sampler closely follows the ISO 7708/CEN sampling criteria for inhalable particulate mass at 4 L/min. A convenient conductive plastic transport case is available for shipping the filters to a laboratory for analysis.

Collection of Inhalable Bioaerosols
The SKC Button Aerosol Sampler provides superior collection of inhalable particles including bacteria and fungal spores. Use the Button Sampler with a 25-mm membrane filter such as MCE or PVC to collect bioaerosols for non-viable analysis. Using SKC gelatin filters with the Button Sampler helps to maintain the survival of stress-sensitive microorganisms during short sampling periods for viable analysis. Polycarbonate filters are ideal for sampling multiple bioaerosols. The Button Sampler is used with a sample pump capable of 4 L/min for personal inhalable particulate sampling following the ACGIH/ISO criteria.

Operation
The SKC Button Sampler is easy to operate. Simply unscrew the inlet section, remove the PTFE O-ring, place a conditioned and weighed 25-mm filter on the stainless steel support screen, replace the O-ring, and screw the inlet section back onto the sampler. Connect the Button Sampler to a personal sampling pump; clip the sampler onto a worker’s collar and the pump to the worker’s belt. Sample for the appropriate time period.

Button Aerosol Sampler with Calibration Adapter

An easy-to-use calibration adapter is available for the Button Sampler. Simply push the calibration adapter onto the Button Sampler inlet and connect the adapter inlet to a flowmeter. Calibrate to 4 L/min.

About Using Gelatin Filters with the Button Sampler


For maximum microorganism survivability and superior collection of inhalable-size bioaerosols, use gelatin filters with the SKC Button Sampler. Combining the Button Sampler's exceptional filter collection uniformity and low intersample variation with the nurturing properties of gelatin filters creates a sampler that is most efficient at collecting bioaerosols for viable analysis.
