A while back there was an extended discussion about storing Iodine tablets. I understand that many now use the micro-vial from Blue-Line. I made some containerd from Bic Stik pens which I have used for some months now. I would like to complete the test definitively. Back when I was in college I had access to petri dishes, agar, incubation boxes and the like. I don't now and don't really want to build a bio lab in my basement. If anyone on the forum is working at a university or is a bio. student I would gladly send you a tube of iodine tablets to test. The test would need to be done strictly to be of use but I would think that some raw water from a storm drain or sewer would be adequate. Mix the iodine according to instructions 2 tabs per quart and let sit for 30 min then using two petri dishes culture from the treated water and from the untreated water from the same sample. We should know within a day what percentage of growable bugs were killed. For completeness we should also culture water treated with "new from the bottle iodine tablets" <br><br>Anyone up for this?
