ALWAYS use caution when dispensing the acid solution. It is not terribly dangerous but ALWAYS use laboratory protective eyewear, gloves and preferably long sleeves, pants and closed toed shoes. If you do happen to get it on you flush with large amounts of water. If the acid solution gets into the eye, walk over to a sink and flush water in your eye for 10-15 minutes, call 911 if there is any concern and consult a poison control agency, in the US call 1-800-222-1222. For poison control in other countries check out this website.


The 100 mL Acid solution must be shipped as 4 30 mL bottle to be shipped internationally. This is because it is treated as a Hazardous Material and there are maximum volume restrictions on each bottle shipped. This is the normal strength SO2 Acid Reagent and is not concentrated (the 450 mL acid solution is concentrated). The 100 mL SO2 Acid reagent international version functions normally, use 2 mL per free SO2 test as found in the manual.
