Dispensers have a unique direct displacement piston system that is chemical-resistant and provides safe, smooth dispensing. Units are designed with a unique air purging system that prevents loss of reagents and eliminates dripping or splashing of media. An exclusive reagent guard valve prohibits accidental discharge and eliminates the need for capping the discharge tube when the dispenser is not in use. The volume adjustment knob allows quick and easy setting, and locks the volume into place. The discharge tube can be turned on a 360° swivel, allowing convenient dispensing and safe positioning over the reagent label.
Dispensers disassemble easily for cleaning. Automatic calibration eliminates readjustment. Fully autoclavable to 121°C (250°F).
Basic dispensers have a PTFE system for broad general use. Choose a PTFE-lined dispenser for applications using hydrofluoric acid or a glass-lined dispenser for use with organic solvents.
