THREE FACTS the Laser manufacturers and Cryogen resellers don't want you to know about: 
1) Laser manufacturers cannot legally force you to buy their overpriced cryogen by threatening to void your warranty;
2) Refilling cryogen canisters is not illegal--transporting them after you refill them is;
3) All cryogen produced in 2008 is technically pharmaceautical grade--so it is misleading when cryogen resellers claim that their cryogen is somehow more effective or safer than others.  Nevertheless, to go the extra mile, the Cryogen Transfer Dispenser has a patented filtration system that purifies the gas one step further!

Finally, an invention that enables practitioners to keep a lot more of their profits.  This Patented Cryogen Transfer Dispenser serves three primary  purposes---It  saves about 80% on Cryogen costs, it eliminates countless disposals of containers into the environment and it further purifies the cryogen through a patented filtration system.  Most clinics will recoup the $1500 cost in a few weeks. You can acquire the necessary 30 lb container of Cryogen at most Sam's Clubs for about $195. In case you want the cryogen shipped directly to you or Sams Club is out of it, I will give you a couple 1-800 numbers  from whom you can buy for about about $185, including shipping (NOTE:  At Sam's Club, it's sold as  R134a in 30 lb containers under item # 86244, which is  1,1,1,2 tetrafluoroethane--exactly what's in your cryogen canisters).  A 30 lb
container typically fills up twelve of your 1000 gram containers. Using the unit is simple and anyone in your office can do it.  You hook up the hoses, open the valve, come back a few minutes later and your container is full.
