Reagent dosing

A titration is only as accurate as its reagent dosing system, and the new 800 Dosino^® sets new standards with regard to reliability. Dosino is a space-saving revolution in bottletop design. It works upside-down—with the piston moving from top to bottom; air bubbles remain at the top, near the piston, so there’s almost no chance a small air bubble will move into the tubing and adversely affect your titration results. This fresh design still retains Metrohm’s reputation for accuracy and ruggedness: Dosino has a 10,000 step resolution (1 µl resolution for a 10 ml buret), and it is made of chemically resistant components.

859 Titrotherm incorporates holders for two Dosinos with one-liter bottles without the risk of tipping over. An optional holder expands the system to hold four Dosinos, which stabilizes two additional Dosinos on the benchtop. Rinsing and preparation of the buret can be carried out automatically, which eliminates manual dismantling and rinsing. Every buret is provided with serial and cylinder numbers and supplied with its own certificate.
