The popular Tygon is of the 3603 formulation. It is designed specifically for lab environments, as it is resistant to the effect of miscellaneous chemicals.
Your tube should be marked with a number. What is it?
You can look up the properties at
www.tygon.com . I hear that CL60 is available in Canada, is just as good as Tygon 3603 and is cheaper.
The refill point is best at the top. The bleeding point is best at the bottom. I'm putting a T and a valve at the bottom of my loop, and cutting a hole at the bottom of my case, so that if I need to bleed the thing, I can just prop it up, slip a container under it, then open the valve.
