I purchased a handful of oxalic acid vaporizers off of Alibaba given how expensive they are from the distributors. I bought several to spread the shipping expenses. I have two remaining besides the one for myself. $200 each to cover the vaporizer and shipping costs.  These are wired for 110v plugs and come with an extra cylinder cap, o-rings and scoops.  Email: jm.spampinato@gmail.com or text/call 541-280-0203
