Since I am located in Canada I can not supply you anyway. The system I am considering building will be able to make between 10-25 liters of 80 -85% HTP a day from 35% stock. This system just concentrates the peroxide so you need to start with a clean stock in the first place. I project my material costs to be less than $2000 CDN. However, this is just the tip of the iceberg for HTP production. Even after years of trying I am still getting a cold shoulder the producers of peroxide and have to buy thru middle men. This raises the cost of stock by a huge amount. You also have to deal with zoning laws and local storage regulations. Basicly, it can turn into a real mess - be careful or you may find you have an illegal operation that can result in big fines, maybe jail time. Not trying to stop you but as far as I know no-one is building a simple machine that you just plug in, pour peroxide in and HTP comes out. There use to be such a design but it no longer exists. I have not come up with a design yet that I really like for the production of clean HTP from a stablized stock. There are large number of things to go wrong once you start dealing with a HTP vapour, the number of explosions in the past has also made me leary of publicly discussing designs ideas. You may consider contacting the author of http://www.peroxidepropulsion.com/ who uses ion exchange to clean up his peroxide.
