[labnetwork] Removal of Silane Cylinder

[Mitchell Roselius]

Hi Mike,

We've had fittings seize on gas cylinders before. Could you send over a photo and confirm if it's a CGA or DISS fitting? I will check with our production team how they've handled this in the past.

Thanks,

Subject: [labnetwork] Removal of Silane Cylinder

Hi all,

Columbia Nano has a silane cylinder that needs disposal. Unfortunately, the gas line can't be removed from the cylinder because it's seized on, so I disconnected the line. It remains connected to the cylinder and is about 4 feet long and is bendable. The cylinder is around 20-30% full and is small, size 40 CF.

Because the line is attached, the cylinder can't be shipped as is, and it requires a cylinder overpack.

I was wondering if anyone has any recommendations for a company that can do this type of work that isn't Veolia (already contacted them) or if someone has dealt with a stuck CGA fitting on a silane cylinder.

Thank you in advance!

Thank you,
