Same experience here, in fact mine went through the website as an order, but no follow up. My laziness can only be relied on for so long before I go plan B.professional_drunk said:I was actually going to buy from MHB just to save me from having to run around for all the pieces despite it not being exactly what I wanted (wanted 0.5 aeration stone and flow meter). Sent a message to start the purchase process and still haven't received a reply.
The bottles contain ~100 litres of oxygen, so if you are accurately adding 1L/min for one minute per brew, then in theory around 100 batches, however this will come down if you are running the gas before and after the brew to sanitise the stone.luggy said:I've been looking into starting to oxygenate my wort, just wondering how long will a litre bottle last
The Benzomatic ones I have are 59g for about $30 at Masters.professional_drunk said:Bernz - 40g $33 (that figure seems low, is that right?)
Oxyturbo - 930g $50

The bush reducing brass is handy as it gives you more options by adapting the regulator to 1/2" bsp. I was thinking of going all jg fittings to beer line but it would be a pain to fit the aeration stone and luckily the flow meter is an exact fit for the pvc pipe. The only downside is that the connection from the hosetail to pvc hose isn't the most sturdy, but it still does the job. The flow meter works really well. Turn the gas on full and the dial on the flow meter can hold the gas back until you release it to your required LPM.
Ive got the benzomatic and used it for about 12 maybe 14 brews without my notes in front of me. Still going from the same bottle. So to answer your question, LOTS.Batz said:Someone who is actually using the Tesuco bottles with a flow meter, can I ask how many brews do you get from a bottle?

The build above has the added advantage of the flow meter. Something to think about for more consistency. I have been winging it with my benzo and hitting the predicted attenuation every time with a really good ferment time (4-5 days in most cases)
That makes more sense.TSMill said:Oxyturbo is I think 146g, the 930g perhaps is the total weight of the cylinder.
