General guidelines

To disassemble and assemble the columns follow the instructions below. After reassembling
the column ensure that the column does not leak by performing a hydrostatic leakage test.
When assembling/dissembling attention should be paid to:
1.
Always use the correct size tools. A comprehensive tool kit was provided with the
original column. See Table below.
2.
Ideally components should be at approximately room temperature
(approximately 20° C). If not, take particular care as thermal expansion or contraction may
make components fit more tightly and thus more difficult to disassemble.
3.
Dismantled assemblies should be rested on a clean, dry surface
4.
Pay particular care not to damage the edge of the flowcells
5.
When unpacking columns be careful not to scratch the inside of the column tubes
6.
Be careful not to damage stainless steel surfaces by bumping, knocking or scratching
7.
Do not over-tighten components and use correct torque settings as given in this guide.
8.
Good engineering practices should be followed at all times and operations carried out in
an approved and safe manner.
