Developed for the demanding purity standards required in trace analysis. The release of metal trace is reduced to a level the low ppb range or even the ppt range. The parts that are in contact with media are made of various fluoroplastics (e.g. ETFE, FEP, PFA, PTFE), Al₂O₃-sapphire, tantalum.

• For highly concentrated acids and bases, such as perchloric, sulphuric and nitric acid
• Fast, easy and precise volume adjustment due to inner toothed bar and practical screwing mechanism
• Tantalum spring is for dosing of hydrogen peroxide (H₂O₂)
• DE-M marking
• Optionally with recirculation valve
• Also available with DAkkS calibration certificate.
