FAQ
What does the Back Action 90 geometry offer? The Back Action 90 working end provides a 90-degree angulation, allowing access to areas that straight or standard-angle instruments cannot comfortably reach, making it well suited for dissection tasks requiring precise directional control.
Is the handle reusable and autoclavable? The ZEPF-bIONIK handle system is designed for use with M4x0.5 thread inserts, which can typically be exchanged or replaced. For specific sterilisation guidance, consult the manufacturer's instructions for use.
What is the significance of the Lightred-Magenta colour? The colour coding on the ZEPF-bIONIK handle assists clinical teams in rapidly identifying instruments by type or set designation, improving workflow efficiency and reducing the risk of instrument mix-ups.
