These units provide reliable and convenient reagent dispensing. They feature a fluoropolymer resin “wiping” piston seal that displaces reagent in the cylinder without leaving any residue. This eliminates “freezing” due to piston swelling and crystallization of reagent and offers better chemical compatibility. A grooved positive-lock volume adjustment ensures precise setting and prevents accidental volume changes during use. The telescoping filling tube adjusts to fit reagent bottle. Dispensers are surrounded by a clear plastic sleeve that protects the glass cylinder from breaking, and eliminates the risk of hazardous spills.
ChemSaver® models feature the added benefit of recirculation of reagent during priming, which eliminates the waste previously associated with preparing dispensers for use. The recirculating safety valve can be closed to prevent unintentional reagent flow.
