So, we have this FPLC-apparatus from Pharmacia..
Pharmacia service costs are high, so we usually service it ourselves.
Problem is the rubber o-rings in the pumps. They crumble and leave
rubber-dust that clogs up the filters.
Tried different types of rubber - no luck - even the Pharmacia ones
Have anyone out there found a supplier of O-rings that are able to
successfully endure both the chemical and the physical stress of being
shoved around in a glass shaft for months?
Any help appreciated greatly.
