Ok, I know Equitainers are best and yes I have a few, would like to have 10-12 of them but can't afford them anytime in the near future. I have been looking at the disposable shippers and was wondering which on is the best? I have a few Equine Express II which has worked well for people coming to the farm to get the shipments but have not had to use them to ship Fedx overnight yet.
Versashipper III $20-23 has the thermal shield pouches Clipper $26.50-30 has the foam block that the syringe/tubes fit in. Equine Express II $23-30 you can buy 2 Insulated Syringe Sleeves for $4.64
Have there been any studies comparing the disposables with each other? Does putting the syringes in the thermal shield bag or the foam blocks or sleeves slow down the cooling process and is that good or bad? I have considered when shipping in the summer if I have to use a disposible shippers I would double box them(with a big thermal shield bag and styro-foam in between)??? I know they should only be used 4-5 time and inspected before each use.
I have to preface this post with the fact that we did not evaluate the Versashipper III as it was not available at the time we did the research I am about to reference.
Some years ago, we evaluated just about all of the disposable shippers that were available on the market at the time. We looked at cooling curve, how low the internal temperature got, and how well it maintained the internal temperature in the face of ambient thermal challenges (hot and cold) and for how long. Let's just say that all disposable shippers are not made equal and leave it at that...!!
The two disposable shippers that we found worked the best were the Equine Express II (Exodus Breeders Supply) and The Clipper (Hamilton Research Inc.), although neither performed as well in significant ambient temperature trials as the Equitainer.
We often caution people about using the disposable shippers in the height of the breeding season in hot climates and get a response such as "oh, it's not hot where we live, so it's not a problem". Bear in mind that most FedEx shipments go through their hub in Memphis, and it's hot there in the summer!! And furthermore, the back of all courier vans gets hot at some point in the summer...
Now, some stallions have semen that you could ship in a cardboard box without any insulation and still have excellent quality when it gets where it's going, so you also have to figure in individual stallion effect and be prepared to make changes based upon that too.
Another thing to consider is that that these are disposable! They are not meant to be used multiple times and may be subject to damage during shipping - which may be microcracks invisible to the naked eye, which will allow ambient temperature to affect the contents even more as the insulation is damaged. Use once and discard! We have received semen from some very well known and respected Quarter Horse farms in Texas in beaten up and obviously re-used disposable shippers - even though the farms have a $350 collection fee and their own labs to do the collections. They may be respected by others, but they do not receive our respect as they are reproductively irresponsible and should be ashamed of themselves for being so money-grubbing at the cost of their mare-owning clients (this ticks me off a bit - can you tell??? ).
Also consider that every time a disposable container is disposed of, another piece of a landfill somewhere gets something put in it that will not break down for eons...
OK... I guess I answered your question based upon our past research and them some! I'll step off my soapbox now...
