• 4 L/min flow rate enhances sensitivity



• Follows closely the ACGIH/ISO sampling criteria for inhalable particulate mass at 4 L/min



• Low sensitivity to wind direction and velocity



• Reduces electrostatic effects



• Small and lightweight



• Reduces oversampling of very large particles



• Suitable for collecting bioaerosols for viable or non-viable analysis



• Kit available for sampling heavy metals during abrasive blasting



• Autoclavable



• Ideal for personal and area sampling

The patented* 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 ACGIH/ISO 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.

* U.S. Patent Nos. 5,954,845 and 5,958,111

Performance Profile

Operation

The SKC Button Sampler is easy to operate. Simply unscrew the inlet section, remove the Teflon® 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 primary standard calibrator. Calibrate to 4 L/min.

Abrasive Blasting Sampler for Heavy Metals

SKC has created an Abrasive Blasting Sampler for Heavy Metals Kit that contains a Button Aerosol Sampler and a protective shield. This sampler is designed to withstand the mechanical stress from blasting operations. The sampler’s shield protects the filter from shredding or being overloaded by large particles thrust into the sampler. The Abrasive Blasting Sampler for Heavy Metals efficiently collects inhalable heavy metal particles# with low sensitivity to ambient conditions. The U.S. military has used the SKC Abrasive Blasting Sampler for Heavy Metals during abrasive blasting operations. The sampler withstood very high particle concentration and provided recoverable samples and meaningful exposure information.

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 plus non-viable analysis
