(Cat. No. W855008)
Simple, Natural Movements
Both pistol grip and two-ring handles fit any hand in a comfortable way. Activation
performed with limited effort for efficient work even during long dispensing series.
Volume Selection - Reliable Reproducibility
Volume is set within seconds. It will not vary while activating the syringe, thanks to
the safety-locking nut on the micrometric screw. Dose by dose reproducibility (CV) is
excellent, as witnessed by performance figures.
Plunger Tightness without O-ring
Smooth plunger travel and tightness achieved through high precision stainless steel
plunger and grounded glass barrel. No O-ring to mess with or replace.
Glass Protection
Interchangeable glass barrel is protected by a PVC sleeve (not autoclavable) to prevent
breakage.
Few Part Assembly - Low Maintenance
The automatic syringes are made of only six main parts, easy to disassemble. Fast
access to all elements allows rapid and efficient cleaning. Spares are available at
reasonable costs.
