Processing Angioplasty film fixing times

[JohnMeadows]

I scored some old angio film on eBay to use for interrogatives for cyanotype/van dyke brown printing. When developed in dilute dektol (1:4) it gives decent tonality so it should work fine, bt my question is, should I treat it like regular film or photo paper when it comes to fixing. Visually it clears very quickly, but I don't know if it needs 60 seconds to fix properly (using Ilford Rapid Fix) or 5 minutes, followed by hypo-clear. the box it came in is taped/marked up, so it doesn't give any clues.

Thanks in advance for any suggestions!

John

i have no idea but being a cardiologist i find this interesting.

The general rule is twice the clearing time, and you might go three times if there is a dye that takes longer to clear.

Thanks David. In that case about a minute seems right.
