Glass contact area jammed
8-6.
If grease on the glass contact areas becomes hard and the respective parts are difficult
to separate, take the following steps;
1)
Discharge anolyte and catholyte.
2)
When using a glass port plug, warm it up with a hair dryer or something similar
to soften KF grease before removing. When using a PTFE port plug, remove it
after cooling the titration flask in a freezer for about five (5) minutes.
Warning!
Do not try and open solidified jointed parts by force.
Glassware may break into piercing pieces for injury.
Do not warm up a PTFE port plug when removing it as doing
so may inflate the material and the titration flask may be
broken.
