broke the clips for my nanostream

My clips broke off what you I do? Can I buy new one or fix?

Roger- There are lots of broken clips out there on these nanostreams. I am considering buying but wondering when a fix is coming.

The following is a quote by Roger from 09/08/07

To start I think this needs to be put in persepctive. From what I have seen about 10% of clips break, the vast majority the tabs break, braking arms is pretty rare and usually due to a badly overheated part. They break not because the design is truly faulty but because the design is beyond the capability of our molding machines to consistently produce properly. They get burned in the mold. The Lexan is plenty strong and I have seen clamps that were perfectly made be thrown across the room, slammed on a table and curled into an O in the palm of the hand and not break. The reason it took so long to address this was exactly that, we could not break the samples and the first reports came from the US (the pumps came out first in the US) and transport and handling was initially blamed. Lexan is one of the strongest plastics, unfortunately when burned it becomes carbon which is not to strong. There will be no formal recall.

In about 4 weeks we should have a stop gap fix, thicker tabs.

In a few months we will have a new clip design that will utilize the large holes in the magnet holder to clamp to.

The arms will likely be widened slightly but this breakage issue can be controlled by more careful programming of the molding machine and more thorough inspection during a batch run and it is infrequent enough that I don't see at as being a major issue that needs further redesign, especially since any major change will compromise other features and needs of the part like ease of use and movement of the pump.

Basically, if your clamp breaks within the two year warranty period you will be sent the current replacement.

The fix will come faster than initially thought, we should have a new clip in 3 weeks. We are changing the plastic. While I was in Germany we tried a couple other plastics and the results were pretty good, the new plastics are soft and flexible so they don't snap, the one problem we had was the softer plastic compromised the grip of the tabs because they lost the springiness but they were pretty much unbreakable. In the last week they found a new tab shape that could work with the softer plastic. This will be the permanent fix, a softer springier plastic and thicker z shaped tabs.

To para phrase something I read in a book on plastics and engineering- "There is no such thing as poor quality plastic products, only the wrong plastic for the job."

thanks roger and jstlsn!

Just to double-check some info - iif i happen to decide to buy nanostreams now before the fix comes, from what i understand the new tabs/clips will work with the existing nanostreams. So if I happen to break a clip i can get sent the new design at a later date. Am I right about this?

Correct.
