This all-plastic washer replaces costly, antiquated devices that are often more fragile than the cuvettes they wash. Comes complete with a 500 cc polypropylene vacuum flask, Vikem vinyl stopper, and 3 of PVC tubing ready for connection to a vacuum line. The mouth of an inverted cuvette is pressed against the rubber cushion to induce suction. Water or other cleaning fluid poured into the 89 mm (3.5") diameter funnel is forcibly sprayed into the cuvette and then drains into the flask. Research, industrial and healthcare professionals rely on SP Scienceware for their sample handling needs.
