NOTICE
When filling the column tube with a slurry containing a salt
solution take care not to spill onto the top bayonet while pour-
ing, and also to fill the column up to the start of the glass incline
only. This is to avoid corrosion of the metal components of the
column. If spillage or over-filling occurs, remove the excess and
rinse the bayonet with plenty of water before continuing this
procedure.
3
Dampen the adapter rod [802] using a cloth wetted with 20% (v/v) ethanol.
4
Carefully slide the top plate [803] up or down the adapter rod so that it is about 10
cm from the adapter. Grip the adapter rod with one hand on each side of the top
plate.
5
Carefully insert the adapter into the mouth of the column tube at an angle so that
the adapter enters into the liquid or slurry and down into the column tube without
trapping air bubbles. See Figure 4.4.
The adapter shall rest on the tube chamfering when the lid is closed with
the bayonet tools. If the adapter weight needs to be held by the operator
the adapter is not low enough. It is important that the adapter rests on
the chamfering to be certain that the adapter starts to move downwards
when pumping liquid into the hydraulic chamber.
