QF 5.7-1 in Illinois

I have the whizzinator, and a Fieldpiece digital thermometer (HVAC tool). I am pretty new to subbing, only once in real life, but I have done many, many practice drills. I warm the sample to about 85 with running tap water over the bottle, then I inject into the whizz and use 1 regular size Grabber Hand Warmer (I use these because I can easily get the same ones and are on sale a lot, but point is using the same heat pads all of the time - we call this a controlled experiment). I strap on the whizz and I give it about 2 hours to come up, I could shave some time, but this is what worked). If I wear the "whizz" against my bare skin with one pair of cotton boxer briefs (the same pair for each test), I get a temp of around 99, immediately after entering the cup. I saw the strip on the cup at my test at Cadence read 94 a minute or so after. I have done some testing with a 3 oz. bottle and heat pad, but it gets a bit too hot, right now - still working on it with a bottle, next test will be sandwiched between 2 pairs underwear. I also tested the temperature of my own, to see how close to my body temp I was getting, usually around 96.5, immediately after voiding about 3 oz. I bought a pack of hand warmers (10 pairs or 20 warmers) for $5.00 at Farm and Fleet, and found some really good 3 oz. empty travel bottles at Walgreen's (saw them on their web page) for $6.00 for 4 bottles with caps. I cannot over-emphasize PRACTICE, and try eliminate variables if possible. Best of luck to you.
