Hi George, I think that part can be made from an aluminum or a steel tube with proper OD. The ID seems only need to be large enough to allow the glass tube to fit in - depending what is allowed by the two black end adaptors. You can check your engineering department or some machine shops to find some one to cut the tubes, ground the ends and machine the threads for you. Of course you won't be able to see through the wall now, but it will be a very strong column. The expense I think would mainly be labor.

Unfortunately the company does not provide me with additional information regarding plastic type. Although we know that the plastic should stand 700 psi pressure. thanks George From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.UK] On Behalf Of Zhijie Li Sent: Wednesday, March 20, 2013 9:13 PM To: CCP4BB@JISCMAIL.AC.UK Subject: Re: [ccp4bb] column tube Hi George, What is the plastic tube? Is it part of the end adaptors or it is part of the tubing? What type of plastic it is? If you can provide a photograph of the broken part maybe someone can give you more useful suggestions. Zhijie From: George Kontopidis Sent: Wednesday, March 20, 2013 2:28 PM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] column tube Dear Colleagues, Apologies for the non-crystallographic question but it very likely that someone out there may have the answer. I have a chromatography column. Unfortunately the company does not provide a replacement for the plastic tube, which should not cost more than 100 €. The cost for a new column is more than 1500 €! Does anybody know if there is a company that could provide custom-made plastic tubing for chromatography columns?
