• Made of PTFE, with PTFE-encased dispensing piston and PTFE cylinder
• With 2 PTFE adaptors GL 40 + 45, and 1 PTFE intake tube
• Graduation: 0.5ml
• Suitable 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 other 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
• In accordance with ISO standard 8655, ensuring highest accuracy
• By rotating the fine-tuning wheel the volume of liquid can be fixed precisely. The wheel will not move during multiple dosings so the user can be sure that the desired volume is maintained
• No metal spring ensures no contamination of the dosing liquid
• Use of high quality materials such as PTFE and borosilicate glass results in a long life span
