I have recently been using disposable AV liners in my Colorado AV and have had 2 tear (so sad to see that semen dripping on to the ground...) The two times have been with the same stud but I have also collected him many times without problems. Both times were on just the second mount of the phantom, the liner was straight, temperature and pressure about the same as every other time, etc. The liners are from Animal Repro Systems. Anything else I may be doing or could do to avoid this rather dissatisfying outcome?
There are a couple of companies who have liners that are made with a seam, and the seam sometimes has a tendency to tear. ARS is one such company. It doesn't seem to happen to all liners, but it seems that some batches are affected more severely than others - we suspect it is something in the heat laminating process of sealing the seam. With other companies, we know that they have replaced the batch if contacted by the client - I can't say if ARS will do this, but it might be worth trying.
Depending upon what model Colorado AV you have, you may be able to use the non-laminated (extruded) liners from Minitube. These come on a roll, which is not overly cheap, although if you are doing a lot of collections it does actually work out cheaper in the long run. The only catch is that if you are using the newer style Colorado AV from ARS that has the really big rubber pad at the opening end, these liners will not fit over the end so you can't use them. If you are using the older style Colorado that has just the narrower rubber end to it, you will be able to use these liners although you will have to develop the "knack" of stretching them enough to get them over the end without tearing! We routinely use these liners on our French (INRA) model AV (which we prefer to the Colorado anyway as it is a lot lighter!! ) and very, very - did I say "very"? - rarely tear a liner. Like once in about the last 2 years I think! (And we do a lot of collections!).
Thanks Jos The two tears have been right on the seam of the liner. I will try again to contact ARS. I do have the newer AV from ARS with the wide end. I have seen some companies have the all-in-one liners with filters and collection bottles pre-built, may try that.
