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 displays the time needed all in good time exact time-base-controlled dosing at a given rate e.g 15 min at 3.33 ml/min with temperature monitoring if required the liquino calculates and displays the total dosing volume precision pump precision pump working at an exactly defined rate mastering the majority of dosing tasks involving aggressive and/or toxic liquids with temperature monitoring if required tandem operation continuous dosing in tandem operation i.e while one dosino is refilling the other takes over with temperature monitoring if required control and monitoring on the desk 711 liquino ­ the miniaturized liquid handling center the progress of dosing techniques requires new ideas via the alphanumeric keypad of the 711 liquino and the clearly organized dialog complex dosing programs can be set up stored in the 711 liquino itself or on a memory card and subsequently recalled by simply pressing a key · dosing of 30 ml in 20 min · 10 min waiting time mixing time reaction time · dosing of 60 ml in 90 min dosing and measuring in the laboratory 4 measuring controlling dosing in synthesis
