photo The Labmax Bottle Top Dispenser features an air purging system for eliminating air bubbles without loss of valuable reagent.
     The reagent guard valve allows unused reagent to be drained back into the bottle and prevents accidental discharge when the dispenser is not in use. Leakage and the need for capping are eliminated. Volume selection is through the locking rocker switch and sprocket guide.
     Sticking and freezing are eliminated by the patented Teflon piston that fully displaces the reagent with each stroke. The swivel neck allows the discharge tube to be directed 360º around the bottle.
