Storing partially used Sorb.

jhaaja · 21st June 2005, 19:32

No, I take the head off to dry and also the inner scrubber container.

I guess we do things a little different here in the north

I also asked a friend how he does it. He also takes the inner scrubber container out and stores it on his bathrooms floor, never had any problems. He has owned and dived YBOD for the longest time in Finland.

Maybe I will also ask my insructor one more time about this issue.

My question is two fold. How do you store your partially used sorb and how long would you store it before deciding to dispose of it.

Westwinds.

I made a lid for my Classic Kiss. I store it for about a month if needed.

So for how long do you leave the lime in it's canister open to ambient air before sealing it in the unit again ? I try not to leave it more that 24hrs and take care that no exahust in garage or any other solvents are opened !

Oh wow, I don't believe i am reading these responses. They are not just wrong, they are ridiculously unsafe.

Under NO circumstances should you remove the lime, bag it and re-pack it. The partially used scrubber contains used sorb on the inlet side. This leaves you with a reaction front. If you remove the lime, you'll mix up all the used stuff with the unused and you will get premature channeling.

Leave it in the scrubber. If you want to isolate it from the rest of the loop, unscrew the inlet hose from the T and connect it directly to the lid.

The important issue is that you don't let the lime dry out too much. Obviously, if it is absolutley soaked because you've flooded it then you've got more of a problem - under these circumstances i'd probably chuck it.

Storing it in the sealed scrubber is no different to storing it in the canister it is sold in. The important issue is to make sure you put a fill date and hours used label on the scrubber, so when you come back to it you know what that lime has done.

Bottom line - if you remove the lime - throw it away.

Hope this is not a response to my thread, maybe I didn't expalaine myself properly, I would remove the whole scrubber and place it on an upside down cylinder booty with hole in it! About removing Lime from scrubber no way!

Regards

Pierre

Nicely done lid , Philippe, good idea.

Hi Martin
I think what the guys are getting at is to remove the whole scrubber and double bag it. Not to actually remove the lime from the Scubber.

Although in saying I do know instructors that do re-use lime after it has been removed from the scrubber usually for pool training, I would have thought this was bad practice, I know one that came up with a nasty headache.

Cheers
Chris

For the prism unit I'm going to make (mayby tonight) a container out of a six inch (unused) sewer pipe with screw end cap and blank end. Should keep things sealed.

A couple of points.. I'm well aware of the "front" argument in the way sorb is used, versus the mixed sorb absorbing CO2 version. I am interested if there is any published data in respect to this..

Secondly, I placed some used sorb (which I was going to throw out..) into a tupperware container after a dive but for whatever reason I didn't for 3 weeks. I noticed when I lifted the lid that there was black mould around the lid and around the top of the container.. The condensation trapped in the sorb created the moisture for bacterial growth.... so, to the baggers.... caution...

Cheers, JDZ

No need to manufacture a lid or a new storage canister.

The Sealine Baja 5 Dry Bag is the perfect size for storing the Evolution scrubber basket. It fits in perfectly, rolls up and is very durable. (I think it's a bit too short for the Inspiration.)

jdz · 22nd June 2005, 02:38

Hi Pierre,

I am concerned that the scrubber basket in the prism is fragile and needs lots of TLC... The Prism baskets have been known to break! Hence I was going for a rigid storage device over a soft bag..

A further point I left out before when storing the scrubbers for long? periods, some Orings used in sealing scubbers, like the prism's, are more soft silicon based and if the are left in position for any length of time, they will swell or dry and "adhere" more vigorously and either make the unit harder to pull apart and/or damage the oring on removal..

Cheers, JDZ
