ATTENTION
When removing and reinstalling the seals, make sure not to damage them.
Never apply grease to the seals and never touch them with sharp objects, otherwise they will get
damaged and cause solvent loss.
To prolong the lifetime of the seals, rinse them regularly with distilled water or alcohol. Afterwards, dry
them with a soft cloth.
7 .8 Glass sample tubes
The glass sample tubes can be cleaned using commercial cleaning agent or in a dishwasher.
7 .9 Solvent beakers
The roughened area at the bottom of the solvent beakers prevents solvents from bumping. In order to
maintain this area in active state the beakers must be cleaned properly after every extraction.
