    It was some 4-8 mesh in a pale blue can. I got it in Mexico and it was sooo much cheaper than sofnolime.

    The writing was in Spanish and I don't recall the brand but the cab driver said it was good sheeet

    From my class: the medical grade sorb has significantly less trapped water. Hospitals climate control systems add humidity to the air constantly to keep it at a functional level. If I remember correctly, the diving grade stuff has a lot (25%?) more water. Since the scrubbing reaction happens at the aqueous layer, the amount of trapped water really matters.

    One time, I accidentally forgot and left my RB in the car in the sun and it dried out otherwise fresh sorb. On the next dive I had a CO2 hit, but not until my workrate spiked. I bailed out and survived. Afterwards I took the unit back to the hotel and went for a couch dive. 20 minutes sitting around on the loop, no problem. 2 minutes doing squats laid me out flat.

    The moral of the story is, use diving grade sorb, and don't let it dry out. Also when in doubt bail out. ;)

    Hi testuser, Grace medical grade sorb has normaly the same moisture prrcentage as diving grade - mean standard medical grade sorb, but the LF - low flow medical grade sorb is the dryer sorb. So away from LF or LoFlo sorb..... this is explanation from Grace.....

    Medical grade Sodasorb 4-8

    I missed it, but did anyone get a definitive statement on the difference between the HP an the normal Sodasorb (not the LF stuff). The label says it is the same moisture.

    In perspective, I dive in warm water, and use the HP to manufacturers standard recommendations in my units, use 797 longer, and have old bits and bobs of half used tubs I use for the pool. I'm wondering where straightforward Sodasorb would fit in this.

    Well the supplyer here in Slovenia
    Is stating HP and standard medical grade sodasorb are the same, with just dust contents being difference. HP has more dust.
    Mabe it would be the best to write to Grace...

    to all,

    maybe a bit harsh, but I don't get this:

    people died when diving medical grade sorb!

    and w're having a whole discussion on whether or not using it?

    only use the recommended sorb by the manufacturer!

    paul

    ps: and if you still don't believe it: we tested different sorbs: there is HUGE difference between real rebreather sorb, and medical sorb: in some cases the durations for medical are not even 10% of real rebreather sorb, when tested in cold water, at CE conditions!
    www.rEvo-rebreathers.com
    ...."Yes you have to pre-breathe to activate the scrubber sorb, anyone who says different doesn't know what they are talking about!"...
    .... to get more accurate CO2 injection in the breathing machine we put 2 mass flow controllers in series ...
    .... The noise is a few tens of nano-volts, so DL were able to reduce the output voltage ...
    .... radial scrubbers give longer dwell time than axials...
    .... the earth is flat and ...

    Hi Paul,

    Thanks for your koments. Sure you have more data than we do, so I belive you.
    On the other hand statements from sorb producers are somewhat different so the discusion was expected. My goal was to involve someone that knows more than we do and get some real data....
    So can you please share your findings with us?
