A titration unit with a reagent recirculation system for motor-powered titration directly from the reagent bottle. Available in three volumes (10 ml; 20 ml and 50 ml). Electronic control of titration enables the achievement of reproducible results and precisely defined dynamics each time. Time-saving rapid titration with subsequent fine titration enhances accuracy and efficiency. The titration impulse triggered by the motor enables the achievement of a droplet break-up with output volumes from 10 µl to 99.999 ml and delivers resolutions up to the third decimal place. Electronic control and dispensing of volumes. A light protection window for the valve block is also included in the scope of delivery. Titration impulse triggered by the motor enables the achievement of a droplet break u p from 10 µl for precision determination. Media recirculating system for simple and rapid venting without reagent loss. Free rotation. TFT touchscreen with user-friendly menu. Method memory for nine different titration procedures with storage o f all settings. USB and RS232 interface for PC connection. Integration in automated procedures possible. Discharge valves and valve seats consisting of high-purity aluminium oxide ceramic. Power supply 100-240V; with EU; UK; US plug. Supplied with: opus® titration complete with thread 45 mm; 3 adapters (A 32; A 38 and S 40); 1 screw coupled suction tube; 1 titration discharge unit and 1 power supply; 1 brown light protection window; touch screen module titration; Data Power Cable 0;75 m; instruction manual; single calibration report.
