Your search is over! One dispenser for (nearly) all liquids - even for hydrofluoric acid!
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.
For security reasons, the dosing piston and the dosing cylinder are very tight, so that it can only be moved with some effort. Therefore, the HF dispenser should be fixed to a stand or must be operated with both hands, that means you will hold the bottle with one hand and dispense with the other hand. A bottle cuff is not sufficient.
