Someone PM’d me a Q “what water container do I use for a SteriPen” and my answer kind of bears on some of this.
I’ve been using 1-quart (liter?) Gatorade bottles. Light. Free at the recycling center. The 1.75-pint and smaller have smaller lids that barely fit my red-cross-branded SteriPen, while it fits well in the 32 ounce size.
But I’m looking to switch. I’ve never liked how high up the UV bulb was in the Gatorade bottle with lots of water well below it and then I read an scientific article (Drinking water treatment with ultraviolet light for travelers …www.sciencedirect.com › science › article › pii) reviewing SteriPens with and without agitation and it makes a huge difference – >99.99% sterilizing versus 95% and I know I’m not stirring the water in the Gatorade bottle around much because of the fit on the Steripen (I can use the SteriPen as a stirrer much better in a wide-mouth Nalgene) and the lid is too small to cut out a SteriPen-sized rectangle so as to shake the whole assembly a lot.
So I’m looking for a few Planter’s peanut jars – tall, #1 plastic, hold 16 ounces dry-weight nuts. A much wider lid so it’s easier to fill, much easier to use the SteriPen as a stirrer, and a big enough lid that I can cut a hole in an extra one to insert the SteriPen through.
And for a thru-hiker, you could always grab another at any super market or Walmart. With 2,720 calories of peanuts inside.
I’ve been using one as a pee bottle and it’s 1.9 ounces bottle only, 0.2 ounces for the lid. 2.13 ounces total. It holds 29 fluid ounces, so just shy of a quart. The lid is pretty watertight – not bomber like a Nalgene or a soda bottle, but better than a PB jar and fine for being upright in my pack’s side pocket.
For cold-soaking couscous into a cold, gloopy mess, a PB jar would be better being a bit wider and a bit shorter, but I’d prefer the Planter’s nut plastic jar as a water bottle.
