This floating Artificial Substrate Sampler was developed for the EPA and other groups interested in sampling for comparative conditions of water quality.

It is placed in a stream, reservoir, or lake and is secured by means of a line and anchor (not included) attached to the Locking Rings. The lower bend in the wire frame allows for bottom anchoring and/or holding the sampler below the water surface. A deflection plate helps provide a quiet water flow area for best biotic growth and is made from a flexible water and sunlight resistant plastic.

It is left in place for two weeks during which time algae grows on the glass slides. At the end of the sampling period the slide trays are easily retrieved. The algae and other growth on the slides can then be examined for identification and counting.

Manufactured from impact resistant ABS plastic with stainless steel hardware, it will withstand the stress of attachment to anchors and buoys, a necessity for sampling of the zebra mussel. It features 8 slots that will hold up to 16 standard microscope slides (two slides in each slot). In addition, the periphyton sampler will accommodate alternative sampling media such as fibrous filter cartridges.
