- Safety recirculating valve that eliminates reagent waste during priming of the dispenser; valve can be closed to prevent accidental dispensing
- Fine volume adjustment that enables user calibration when dispensing viscous or high-density reagents
- Slide-n-lock volume adjustment
- “Wiping" piston seal design
- Telescoping filling tube
Wiping piston seal eliminates the problem of the piston swelling and freezing. Reagent is wiped out of the cylinder with each stroke to avoid lingering residue. Filling tube easily adjusts to fit the size of the bottle without cutting. The length can be readjusted for different bottles. A clear plastic sleeve protects the glass cylinder from chemical hazards. Includes an individual calibration certificate of conformity from GLP performance documentation.
