Abstract
The miniaturized sampler is activated by a diaphragm motor that can be screwed together by hand. The sampler uses an elastomeric collection head and typically takes a small sample each time the diaphragm motor is activated. The collection head is connected to a piston by a pin and ring arrangement that can be economically manufactured and easily serviced. Because the collection head is smaller than prior art designs, it takes less force to activate. A smaller collection head can be driven by a smaller diaphragm motor which allows overall sampler size and weight to be reduced when compared with prior art designs.
