Question for Darin

Post by mote » Thu Mar 06, 2008 12:41 pm

I went to the link for Continental Plastic that you mentioned earlier and looked at their supplies. They have a product called Thermo-SpermC21 that is suppose to be used instead of a gel pack during shipping. If it does as advertised it holds the temperature to 21 degrees Celsius during shipping. I have been told that it is actually more important to have a constant temp than to have the temp set perfectly to 63 degrees F as temperature swings do more damage than being off a degree or two. I am not trying to start an argument as to whether or not the product works as advertised (with all the chemists out there, I am sure it is true), but I do have a question about it. By my calculations, 21 degrees Celsius is 69.8 degrees Fahrenheit. I realize that this is probably a lot better than the way semen is currently being shipped around in the brown truck these days, but is 69.8 to high? Also do you know what they are charging per pack and how many you need to add to a shipment to keep it regulated properly?

Thanks for your time.

Good question!!

The way the product works is this:

It "changes phase" from liquid to solid (or vice versa) at 21C. Just as water changes at 0 degrees C from liquid to solid. When ThermoSperm is exosed to temperatures below 21C it expels energy to try to maintain a warmer temp. until the ThermoSperm packs become solid as a rock and there is no more energy left to expel. When they are exposed to temps. above 21C they absorb energy (heat) trying to maintain a cooler temp. until they are very liquid and soft.

Why 21C? Because the environment inside the shipping container is expected to vary depending on the climate during the season in which the shipment is made, and as the ThermoSperm change phase to control the temperature fluctuations, the temp. inside the container can sometimes vary within a 5 degree range. Since the ideal storage temp. for semen is 16C, if the packs were set to change phase at 16C, it is possible that temperatures inside the shipping container could reach as low as 11C. That could be damaging.

In studies against gel packs, ThermoSperm have been proven to maintain the proper storage temperature inside the container for a longer period of time when exposed to both hot and cold outside environments.

Sorry for the blatant commercial, but this really is a good and innovative product that not enough studs are utilizing.
