Hi everyone

We are planning to buy a Waters UPLC rated up to 1000 bar and I think about how to connect everything pressure-proof. Could everybody please share experience on which tubings and fittings are used? I found these https://www.idex-hs.com/fluidic-connect ... vel-x.html and Thermo's Viper (http://www.thermoscientific.com/en/prod ... stems.html) promising but I am open to alternatives

Regards

Currently i'm only having experience with Agilent A-Line quick connect fittings and they do job good.
I heard a lot of good about Thermo's Viper but unfortunately had not been able to acquire one to test yet, also don't know the price comparison.

here is our newsletter on our SmartFittings for Ultra-high pressures. It also describes different tubing:

Let me know if you have questions

What about reusability? Our working area requires frequent change of columns, so my main concern is that after 10 tightening/untightening cycles the integrated ferrule might be worn out. The MarvelX state "up to 200 times reusable" whatever "up to" means...

We are using our fittings in our QC stations and each runs 5-10 columns a day (meaning 5-10 installations), I don't remember when the fittings were installed but probably few months. Our fittings are finger-tight and unless you are using pliers or a wrench, I don't expect any issue with ferrules.
