2111 Diffusion Tubing

Diffusion Tubing for Reagent Bottle Adaptor
in 3 parts, using Items T2194-45 >>> T2194-4512

Yes, the diffusion tubing should be an issue.  It's been an issue with all the changes.  If you're bundling DIPA with the tubing from the OEM, your paying way too much.  Can it be done with just three parts? We think so!

Pictured left is the reagent bottle adaptor shown with DS&M tubing.

One gets an excellent visual of the connection with caps off. (see instructions)
To install DS&M tubing: Leave those extension adaptors M/F on the reagent bottle adaptor. [the new 2111RBA comes with a diffusion tubing set-up].  
Replace the polyethylene barb with the PEEK (tan) barb.  Push the tubing onto barb keeping o-ring between the barb and body. The orange(silicone) o-ring acts as a cinch, and will last as long as the tubing.  PEEK is completely resistant to the DIPA, and those are machined barbs for a good snug fit.  
All you should need to do is replace the 4" or 8" piece of diffusion tubing with the O-ring cinch.
T2194-4512 is a bakers dozen of 4-inch lengths with O-rings attached, a set of PEEK Barb adaptors and 2 spare o-rings.
With or without the caps you will still find it easier to change out the DS&M diffusion tubing.

For a full comparison of the diffusion tubing go here 2111LL Diffusion Tubing, which is a little Acrobat booklet.

I'm sure many 1800 Series users got in the habit of buying the diffusion tubing packaged with the monoethylamine.  You may want to rethink that with the DIPA. This is a small piece of tubing, and the aging effect from the DIPA does not seem to be as predictable.  We're offering the diffusion tubing in a couple of ways, which I believe will instigate some major cost savings, especially when buying DIPA, D3045R-6L (Reagent only).
One, T2194-45
is with 12 barb adaptors=6 tubing(s), which you can use to get multiple analyzers converted.

The other T2194-4512
is 13 tubing(s) and
2 spare barb adaptors to keep one analyzer changed out monthly.
