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.
