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. In order to meet the requirements of the market, the volume range of the FORTUNA UNIVERSAL OPTIFIX HF dispenser has been extended by 2 sizes: 5 ml and 50 ml
