U tubes/ drying tubes

[ellice]

Hi all,
I am trying to find U tubes/drying tubes, that are 100mm in length. I find the carbon rods sit perfectly in them. I have some here that were purchased some time ago, but the shortest ones from suppliers are 150 mm. Any help would be appreciated.
Regards, Ellice.

Hi Ellice,

I've found some U-Tubes, but they are 150mL. They have a side-arm off both 'u-ends'.
Let me know if they're any use to you.
