The FORTUNA UNIVERSAL® OPTIFIX® HF is available for dosing of all media that can be handled with by other OPTIFIX® dispensers and in addition, for hydrofluoric acid. The dosing cylinder is made of PTFE so that the dosing liquid does not come into contact with glass. The finger protection cap is white, with a blue colour code. Confusion with the yellow OPTIFIX® dispensers is not possible.
