The pulse-free dispensing technique of the burette continuous makes titration in the laboratory safer at a high-level of precision. The burette continuous can be used for titration media up to a concentration of 2 Mol/l. During the titration process, the burette fills automatically, eliminating time-consuming refill steps. The burette continuous undercuts especially with partial volumes the margins of error defined by DIN EN ISO 8655-3. All operation controls and the digital display have an ergonomic and functional design and are arranged clearly for easy and safe operation. The pulse-free dispensing technique for continuous and quick titration (5 ml/sec) is a further step in gaining efficiency for routine and tricky titration's. The innovative re-circulation valve allows for re-circulation within the closed system in order to avoid unnecessary reagent waste. A true timesaver is the elimination of filling procedures. The clear and precise display shows the titrated volume, which may be in the range from 0,010 ml to 999,9 ml. The dispensing volume is set per hand wheel rotation, 2,5 ml for the continuous E, or 5,0 ml for the continuous RS. The burette may be calibrated. The easily replaceable micro-batteries allow an operation independent of an external power supply. The device can be rotated on the bottle for 360° and shows a service-friendly modular design. The telescoping intake tube extracts from 200 to 350 mm and several adapters for drying tubes and filters are available. It comes with a certificate of conformity according to DIN 12600.
