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 20 slots that will hold up to 40 standard
microscope slides (two slides in each slot). In
addition, the periphyton sampler will accommodate
alternative sampling media such as fibrous filter
cartridges.
The periphyton sampler is available in three
different configurations depending on your specific
sampling needs. Slides sold separately.
Variable Depth Model - Take samples at
different water depths. Sold complete with
directional wind vane to position the sampler plus a
stainless steel pivot pin and "S" hooks which are
used to anchor the sampler onto buoys.
Floating Sampler - This sampler collects
periphyton samples just below the surface of the
water. The float hardware positions the sampler
inconspicuously below the water's surface in an
orientation that will not capsize.
Sidestream Sampler - Sold complete with
suction cups that can be glued or fastened to the
side of docks, buoys, or any flat surface.
