Local source for pH10 buffer solution

[eric]

Anybody know a local (Austin) source to get a pH 10 calibration buffer?

I generally go to Austin Homebrew, but they carry 7 and 4. Since I'm testing more alkaline, I'd rather calibrate to the high end.

I would like to know as well.

I read on RC that you can make your own using borax and water. It has a pH of 9 or so. I would have to find the article though.

Check the yellow pages for a scientific supply store. We have one here, I'm sure there is one in Austin. You might also check with Misti as she is a chemistry teacher.

Check with alex at wolf reef, I got some from him last week and he still had some.

I believe we were looking for a LOCAL source to Austin. I was not aware that Alex had opened a store up here.

[alexwolf]

Im sure that Jim1000 was just trying to offer a suggestion.

[Polkster13]

I know he was but he should really read what the authoer was asking before replying. I have nothing agaisnt your store. Been there and really liked what I saw. BUT we had asked for a local source and SA is not local. Have had a bad afternoon and it is probably showing. I guess I should have added a :P to my last post.

[alexwolf]

its ok, I dont have any in stock anyhow :D

[Polkster13]

LOL, too funny. :lol

Is it time to go home yet? Almost, three. Just a little longer and I can go home and enjoy watching my reef tanks. :innocent :skeezy

[eric]

Alex, You got any more coming in the near future? I was intending to find an Austin source, but I'm in SA often enough, probably sometime next week. Give me a chance to see the shop.

The science supply store I found here is an online mail order place (not that they had any in the first place).

[alexwolf]

I have like 10 packs of 7. How many do you need? Lemme see what I can do.

[JimD]

Eric, I have a few packs of 10.

[alexwolf]

There you go!

You still gotta come by the shop though :)

[JimD]

Alex, what type of ballast are you running your DE's on?

[eric]

I have 7.0 and 4.0, I want pH 10.0, though. (that's a lot of oh sounds)

Really I'm just looking for a couple of packets. I believe I can order it from MarineDepot, but I've got nothing else I need there. Just trying to avoid a mail order for $5 worth of stuff.

Ah, I might just have to contact Jim!

[Polkster13]

Jim,

How much do you want to the 10.0 calibartion packs?

[JimD]

I only have a few, but if you need one you can have it for free, just come get it! When yo order some for yourself, just add one extra.

[Polkster13]

Will do. Will you be at the next meeting? If so, can you bring it then?

[JimD]

Not sure yet if Ill make the meeting or not, probably wont know till the day before, I dont do large crowds well... lol

[Polkster13]

Me either, but that is another story. Maybe I can drop by before or after the meet if you don't make it. Do you still have my cell phone number?

[JimD]

That would be cool, nope, dont have that number.

[Polkster13]

Sent you a PM with my numbers.

[eric]

Thanks again JimD.

I recalibrated using the 10 instead of 4 (after the 7 as instructed by my 'structions) and the same water before and after tested .2 higher. 'zactly what I thought.
