Chemical resistance
The columns can be used in aqueous solutions and almost all the 3
organic solvents commonly used in liquid chromatography of
macromolecules, with the following exceptions: 2
• chlorinated hydrocarbons 1
• acetone and other ketones
• aliphatic esters
• phenol
Cleaning
Suitable cleaning agents are soapy water or laboratory detergents.
Enzyme detergents are recommended for removing proteinaceous
contaminants.
The column can be autoclaved without the thermostatic jacket,
tubings and net ring. Alternatively, the entire column may be
sterilized with ethylene oxide. The built-in sealing rings on XK 50
column contains a metallic spring.

procedure in the resin instructions.
Column Packing Procedures
Packing the column (a) (b)
1 Remove the column adapter and make sure the column end
piece is in the right place and the O-ring tightened.
2 Pour a small amount of packing liquid into the column tube and
let it drain until the level of liquid in the tube is 1 to 2 mm above
the bottom net ring.
3 Close the column outlet on the bottom piece using a stop plug.
4 Carefully fill chromatography resin through the packing reservoir
into the column tube. Avoid introducing air bubbles.
5 Slacken the O-ring of the top adapter and insert the adapter in
the column tube at an angle so that no air is trapped under the
net (Fig 7a).
6 Fasten the adapter to the column tube by turning the end cap
down (Fig 7b).
7 Slide the adapter down using QuickLock to 1 to 2 cm above the
resin bed (Fig 7c).
8 Tighten the end knob to seal the O-ring against the column wall. (c)
5 Put the cap on the packing reservoir and make sure the liquid is
pressed through the capillary to avoid trapping any air.
