forget dropping funnels electronics and wet section clearly separated relief for encumbered fume cupboards the dosino sits on top of the reagent bottle and therefore requires very little space keypad and electronics are separated from the wet chemistry you monitor the reaction from your desk the dosing programs that can be performed may be grouped as follows dispensing functions in the xdos mode the new dosing experience the «electronic dropping funnel» doses a fixed volume with temperature monitoring if required in a given time interval e.g 3500 ml in 500 min the liquino calculates and displays the dosing rate and automatically takes into account the cylinder volume of the dosing unit dosing/temperature curves and reports for the lab journal can be printed out gradient dosing gradient dosing with serial control of up to four dosinos dose a fixed volume with or without pauses at a defined rate e.g 230 ml at 22.5 ml/min with temperature monitoring if required the liquino calculates and

safety first programming of a sequence seq free programming of a dosing sequence allowing the combination of different dosing modes this makes complex dosing profiles possible each step mode has its own parameters between the sequences pauses date time or time interval of any length can be inserted a sequence may also contain additional auxiliary instructions e.g to control external instruments scan control or to control the sequence pause timer storage of dosing sequences once the dosing sequences have been optimized the corresponding methods can be stored on a memory card and reproduced at the press of a key safety with exothermic reactions optional pt 100 temperature sensors in four-wire technique with «synthesis-proof» ptfe shafts are used for the temperature monitoring during dosing tasks upper and lower limits with individual alarm outputs complete the safety measures if a limit is exceeded this can be made to stop the dosing automatically or to switch on or off a heating or coo

maximum accuracy outstanding precision pump the dosing error and the repeatability are better than required by din 12650 in terms of accuracy and repeatability the dosino is far superior to volumetric standard glassware the resolution of the cylinder volume amounting to 10 000 steps allows precise dosing at rates that can be set between 0.0015 ml/min and 9.96 l/h auto control with built-in glp test for the automatic validation of the pump or cylinder respectively the 711 liquino is connected to a balance via its rs 232c interface the integrated glp dosing program automatically doses the liquid into a vessel tared on the balance calculates the volume of the liquid dosed and compares it to the nominal volume the validation report conforming to glp appears on the connected printer expansion possibilities the rs 232c interface built in as standard allows the remote control and programming of all dosing functions from a pc printer for the comprehensive documentation of parameter settings an
