RE: Kapton capillaries

Mike,

I tried to make cellulose capillaries as well, but my product came out to be 
quite fragile. Also, I couldn't find an easy way to fill them. Do you know the 
tricks?

 Then stretch the wire with pliers and slip off the cellulose capillary. This 
 is cheap, quick, has very 
 low scatter and of course you can make it to whatever size you want.

Try polyimide rather than kapton. We have used MicroLumen as a  
vendor: http://www.microlumen.com/

We use thin-walled heat shrink PET tubing from advanced polymers.  Fewer 
peaks in the low angle region and it comes in a colorless/ clear form.
