Dosing unit FORTUNA® UNIVERSAL OPTIFIX® HF

The OPTIFIX® loop is a patented and safe circulation system to fill and empty the bottle top dispenser. The benefit of this system is a unique, specialised dispensing nozzle which can circulate the dispensed chemical and therefore fill and empty the dispenser without waste. In closed position the loop system prevents aggressive liquid from coming out. The circulation system is made of solid PTFE. As the whole OPTIFIX® bottletop dispenser does not contain any metal parts or seals, it is autoclavable.
