ELI 5 shows the Castellini philosophy. Every detail, from its total ergonomics to the functional design and the hygiene system, satisfies different quality guidelines. It is clear that every version of the ELI 5 collection showcases a specific design expertise that helps the surgeon improve efficiency. The Whip Arm Over Patient Delivery module is made for 5 instruments and built on a self-balancing arm. It is easy to maneuver in ideal and comfortable positions based on the treatment being done. The levers of the instrument and the tubing's length help reduce physical stress on the dentist's wrists during procedures.
