Ive got a waters inline degasser with 2 chambers that cause the unit to fail. Upon inspection under a microscope it looks like there are significant cracks along the gas permeable tubing on the inside of the chamber. The unit works fine with the remaining 2 ports, but I was wondering if I could get away with not buying another 2 chambers at ~800$ each new from waters or 500$ish refurbed from somewhere else by just replacing this tubing myself. Does anyone have any idea where i might be able to acquire replacement tubing for these chambers?

Thanks

Those degassing chambers use Telflon AF membranes, although Waters did not specify which Teflon AF (1200, 1600 or 2400). Teflon AF tubings can be obtained from biogeneral.

Thanks! Ill see about rebuilding those chambers myself then.
