Ordering Information
- Low sensitivity to wind direction and velocity
- Reduces electrostatic effects
- Minimally affected by orientation
- Small and lightweight
- Follows closely the ACGIH/ISO sampling criteria
for inhalable particulate mass at 4 L/min
- Reduces oversampling of very large particles
(> 100 µm)
- Autoclavable
- Ideal for collecting bioaerosols for
viable or non-viable analysis
- Kit available for sampling heavy metals during
abrasive blasting
- Suitable 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 superior particulate deposition uniformity
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.

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 polycarbonate filter or other membrane filters such
as MCE or PVC to collect bioaerosols for viable plus non-viable analysis.
Using SKC gelatin filters with the Button Sampler helps to maintian
viability of stress-sensitive microorganisms during short sampling
periods. The Button Sampler is used with a sample pump capable of
4 L/min for personal
inhalable
particulate sampling following the ACGIH/ ISO criteria.
Performance Profile
| Flow Rate: |
| |
4 L/min
The Button Sampler closely follows the ACGIH/ISO inhalability curve at
4 L/min. This provides optimum sampling. Sampling efficiency is maintained
within ± 30% at flows ranging from 2 to 5 L/min.

Operation
The SKC Button Sampler is easy to operate. Simply unscrew the inlet section,
remove the Teflon® O-ring, place a 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. |

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. |
* While silica
is commonly found in abrasive blasting environments, the SKC Abrasive
Blasting Sampler for Heavy Metals is not suitable for sampling
silica. Silica sampling using OSHA Method ID 142 requires
a cyclone.
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 Click
