2.2.4 Titration cell with aspiration equipment (utilization with Dosino)
A Dosino allows the automatic replacement of reagents.
For aspiration, the 6.5617.000 aspiration equipment is used, along with a
complete dosing unit and a 50 mL glass cylinder. For aspirating greasy
samples when only the sample and not the whole reagent is to be aspira-
ted, we recommend using a dosing unit with a 20 mL cylinder. For highly
viscous samples, a dosing unit with a 10 mL cylinder is more suitable.
