Todd
Thanks for the info.As for women….be afraid. be very afraid. always.
: )Aug 25, 2007 at 2:15 pm #1399956I tested this out in my bathroom using a 2+ platy and the steripen and it works like a champ so I'll be carrying a 1 litre platy as opposed to a nalgene bottle on my next trip.
I did notice some water inside the glass tube after I tested it but I'm not too worried about it at this point.
Aug 25, 2007 at 2:55 pm #1399959Good to know that the Steripen works with a narrow-mouth platy. What about the smaller size Steripen ("Traveller")? Can it work the same way with a 1L platy? Has anyone tried and lived to tell the tale?
Aug 25, 2007 at 3:06 pm #1399963I don't own a platypus bladder but the openning is about the same size a soda bottle. Their is no way I can tell to jam the adventurer into the openning.

When I get a chance, I'll try it with my Adventurer and 2+Platy with the small opening.
Aug 27, 2007 at 11:11 am #1400114I am holding my breath until you post again. :)
Aug 27, 2007 at 12:13 pm #1400118I can use my steripen adv with small mouth bike bottles but that's about as small as it fits getting the sensor wet. It just barely fits in those as it is. No way the sensor is going inside a small platy or that would save me much timeo.
Aug 27, 2007 at 12:50 pm #1400120Alas, the Adventurer does not appear to work with a regular Platy. (At least I couldn't get it to work.) Oh well, at least it works with the Nalgene Cantenes.

Aug 27, 2007 at 3:30 pm #1400138Mine either. Oh well. I'll just use a cut-up 1L Platy.
Aug 27, 2007 at 3:38 pm #1400140Thanks for all your feedback!
Aug 27, 2007 at 6:11 pm #1400162I use my Steripen Adventurer with a nalgene 32 oz wide-mouth canteen.
I then dump the treated water into my 3L bladder.
Aug 27, 2007 at 6:15 pm #1400163I got my Steripen Adventurer to use with my 32 oz wide mouthed Nalgene Canteen as well. I still have to put it to use. I intend to then pour the contents into my 48 oz wide mouthed Nalgene Canteen.

Aug 27, 2007 at 6:40 pm #1400166This little funnel from Hennessy hammock screws onto the top of a platypus bottle. Use an elstic band to attach a small piece of no-seeum netting over the top, filter oput the "floaties". If you miss a few bugs, remember they are just protien!
http://hennessyhammock.com/new-products.htmlSep 4, 2007 at 8:34 pm #1401065I tried your technique on an extra Platypus cap that I had, but had problems getting the screen to stay in place. After closer inspection, it looks like you used a soda or water botle cap. My cap has a inner ring, which creates a seal on the inside of the finish (top part with the threads) of the Platypus and teh outside of that raised ring on the cap, which prevented the screen from fitting nicely between the cap and finish. Soda bottle caps create the seal between the top of the finish and the bottom of the cap.
Sep 5, 2007 at 8:31 am #1401114Hi Thomas:
I was too cheap to sacrifice a "real" Platypus bottle cap — the caps that come from supermarket water bottles fit well and are much cheaper. Thanks for the feedback about Platy bottle caps.
I assume you now have a bottle cap filter made with a supermarket bottle cap?
Sep 5, 2007 at 10:51 am #1401123An easy way to make sure the Big Zip is secure is to push it against a tree or wall as opposed to using a pinching method between fingers and thumb. Test it by giving a good squeeze.
Sep 5, 2007 at 2:06 pm #1401143To Sean Perry, Chris Wallace, and all others who use their Steripens with narrow mouth Platypus bladders/bottles:
I called and spoke to Miles Maiden of SteriPen (Hydro-Photon) today. Miles explained that the Steripen should be used with wide-mouth or open containers, to allow a full immersion of the glass UV tube. When asked, he specifically recommended against using narrow-mouth containers such as the 1L Platypus.
Finally, for the reason stated above, tests performed by Hydro-Photon and the independent testers were all done using open or wide-mouth containers.
Sep 5, 2007 at 2:26 pm #1401146How do you even get a narrow mouth platy to work ben? The water has to be on the sensor area which is much larger than the glass tube for it to work properly anyway?
Anyway I'll confirm that the glass tube goes all the way inside a standard opening bike bottle and the sensor gets wet providing proper operation (plus it's opaque so you can't see the UV light) :)
Sep 5, 2007 at 2:31 pm #1401147Hi Chris:
Actually, with the Steripen's very narrow glass tube and rubberized base, you can insert the tube into a narrow mouth platy until it "stops" at the rubberized base. Then, you can turn the Platy upside down and agitate — without a drop of water leaking out!
Sean first mentioned it up above, followed by a confirm from Chris Wallace. That got me pretty excited, so I called Miles @ Steripen to confirm effectiveness. Alas, negatore, so I wanted to pass this info back.
Sep 5, 2007 at 2:56 pm #1401155I have an adventurer and while the glass tube fits in the opening it doesn't trigger the metal sensor.
Sep 5, 2007 at 6:28 pm #1401191Well…I have the cap, but haven't had the chance to drill/cut out the hole. Soon!
Sep 5, 2007 at 8:51 pm #1401207I just use my Foster's beer can pot to scoop water to pour into my Platypus. If the water has 'floaties', I jam a bandana into the narrow mouth of the Platy pushing it in to form a small depression I pour the water thru.
Saves that extra half ounce of weight over carrying an 'extra' scoop.
The bandana probably does not work as easily as Ben's mesh cap insert though. It is sometimes a pain to keep it in place with enough of a depression to pour sufficient water quantities thru without the bandana deflecting too much of the water.

Sep 6, 2007 at 4:25 am #1401225I've never actually used the SteriPen/Platy combo in the field, I just confirmed it would work using tap water @ home. Guess I need to get a Nalgene Cantene to use it with. I have some AquaMira but having to wait 30 mins means I would have to carry extra water (I assume)and given it's weight it'd still be lighter to carry an old fashioned filter. Maybe I'll try a gravity filter..
Sep 6, 2007 at 10:09 am #1401264The new UV Aquastar mUV is designed to use in this way, and in my experience works fine with narrow mouth Platys and various plastic water and drink bottles.
Anybody ancient enough to have done their own film developing (you know who you are) know the correct technique: leave some airspace in the container, and slowly invert and return while treating. You'll get plenty of water movement for complete treatment.
It can also be dropped into a pot or widemouth container.
Sep 6, 2007 at 11:44 am #1401272Rick:
Using the device with a narrow-mouth platy — have you talked to /confirmed with Aquastar about its effectiveness? Wonder if they had done any actual testing, etc.?
