• 5-year warranty on material and construction
• Made from high-grade stainless steel and heat-resistant engineering polymer
• Automatic (passive) aspiration occurs when a slight pressure on the plunger is eased
• Self-aspirating without pullback minimizes the risk of needle tip movement
• Can be sterilized by any method.
• New superior surface treatment

Due to the fact that some cartridges (eg Mepidont and Citocartin from Molteni) have a small and rigid rubber membrane comparing to other cartridges, it is recommended to use cartridges such as Dentocaine from Inibsa or others from 3M Espe.

Aspiration is accomplished by the cartridge being pushed onto a hub at the base of the syringe via pressure
from the plunger. The hub causes deformation of the diaphragm, and when the pressure is released from the
plunger, the diaphragm’s elastic recoil creates aspiration by a relative negative pressure in the cartridge.
