2.3.5 Use of the Sample Beaker for Karl Fischer Titration
For Karl Fischer titration the
weighted sample is dosed into
the sample beaker together with
a stirring bar 6.1903.010.
The beaker is sealed with a
centered aluminium foil
6.2820.000 using the foil holder.
During the method run the lift is moved down to the working
position. Thereby, the electrode and burette tips break through the
Al foil. Using Al foil 6.2820.000 this means no risk for the
instruments. This step can be facilitated by binding together all three
devices approx. 2 cm above the bottom of electrode and
burette tips using an O-ring E.301.0022. Thus, the impulse is
focused on a small area of the Al foil.
