Thanks,

Hi - I have been investigating all night -

look at this "Chemfluor® FEP Tubing"  it's 55 Shore soft I was 
thinking of that when doing this "job" - the same as the "old bad 
ones"! The same Shore softness as the ones we have - Nij said it was
"Tygon® Vacuum Tubing Formulation R-3603" and it has also 55 Shore. 

Bingo!

Have the look here:

http://www.tygon.com/new/europe/english/en_europe_index.html

Scroll this side until you find it! It has as I see it everything
I'm looking for - perhaps I'll call England or France tomorrow (hmmm. 
today...that is)

I want this solved - give a damn what it costs - it is just some 
tubes of quality I want! That can't be a fortune!
Maybee the fright is higher...not unusal bying smal no nonce things!


For now I think it is what I'm looking for - shall also talk to my 
friens "hospitalengineer/designer" about it - It's exacly how he 
described what to look for. And it has the same "softness" as the 
ones that we use now! But that's not all - perhaps som inovation is 
to be done - they don't give the diameters on the web - however - 
with some fittings that shall be of no problems.

I was thinking of some selfclosing connections I found anyway - to 
ease maintenance and cleaning! They are made in a way that most small
tubes fit and also if not the exact dimension is found (it's 
european) and are certainly made in the metric system) they may also 
help to connect to the cartriges - using the "old bad" tube to 
connect to the new "real ones". The selfclosing connection is conic 
in bothe directions and you just cut a bit of the cone to meke them 
perfect!

That's it!

Two -three hours sleep now - and then on it again calling England or 
France and have a talk!

They must have resellers in Scandinavia as well!

Problems - hard (somtimes amusing) work - sulution!
Most of anything is out there - the industri must run - we benefit 
that!

Throw out old bad cheap things that don't cost to begin with!

Still I'm a bit upset - seeing what you can get - but an eloge to Nij,
if he hadn't told me what "sh..t" that we used - I would have to do 
one more day of work to find out!
Thanks again NIJ!
Thanks again Jeff!

This is how discussiongroups schould work!
