  4. Periphyton Sampler

    Periphyton Sampler


    Ideal for sampling algae or zebra mussels.
    This artificial substrate sampler can be placed in a stream, reservoir or lake and is secured by means of a line or anchor. It is left in place for two weeks, in which time algae grow on the glass slides. At the end of the sampling period, the slides are removed and the algae and other growths can be examined for identification and counting. Glass microscope slides are held firmly in place in a removable slide tray. The rugged slide tray holds up to 8 slides. Two polyurethane floats keep the sampler self-righting and allow it to float inconspicuously. Meets EPA recommendations. Measures 14 3/4" x 7 3/4" x 6 1/2", complete with 16 slides. Weighs 2 lbs.
