hey boyz, I know this is a little vague but how accurate of a scale do you need for your own conversions? I obviously know the more accurate the better, however, I have a digital food scale at home that is accurate to about 1 g......can this be used? i figure, if you do a 10 g conversion of T-cyp. powder, to be off by 1 g might not be that bad, considering the total? Or should I just invest in a more accurate scale(ie. .01 g accuracy)?

What you have will work if you don't mind chancing your product being =/- 1 g. I use scales that are accurate to 0.0001g (They are in a gravity chamer). -

right next to the bat mobile :D ;)Comment

What are you talking about. The gravity chamber is in the bat mobile....lolComment

Gravity chamber? Anything to do with the chamber of secrets?
My scale is from that epoch though... A classic, maybe silver, scale with a minimum weight of 2/100 carats = 4mg. Very nice for me. :)Comment

How much $? And where can I get one?Originally posted by Growing Doc.

They aren't economical for general home use. The scale you mentioned would be best for your use. A simmilar one is the Fisher accuSeries Analytical Balanace Cat#accu-124D $4032.00 and I also use a weighing slab that minimizes vibrations. I can't find one in the catalogue, but I think they run $300-$400.
Like I said though, this is in a fully equiped lab and used for accuracy in quant assays. You don't need anything like that for home.Comment

So candle, like I said if i'm just doing some home brews of deca and t-cyp. and I want to brew 15g of each......using my digital food scale would be good enough? I know it's not that accurate(+/- 1 g) but if I continuously add small amounts of powder till it clicks over to the 15g mark, then I should just add a little more and be on my way with a slightly overdosed product? Is this cool for what i'm doin'?Comment

Sure. Lets look at worst case scenario. You could end up with 14-16g in your homebrew. Either way it's NBD. When I homebrew I calibrate my scales before use. I use a small set of certified weights that can only be touched with the lifting tool. (Oil from your hands will cause a false reading). If you have access to some highly accurate scales, but can't use them for your homebrew,weigh something close to 15g and see how your scales compair.Comment

I think you can buy balances from Fisher Scientific. Their web page is www.fishersci.com.
some examples:
Ohaus Portable Scout II Series Electronic Toploading Balances
Model S-400 weighs up to 400g with +/- 0.1 gram precision. Catalog # S63396. $230.
Ohaus Triple-Beam Balances: 610g capacity (expandable to 2610g with special attachment) with +/- 0.1g precision. Catalog # 02-032. $135
Ohaus Hanging Pan Balances: 310g capacity with +/- 0.01g precision. Catalog # 02-021. $155.
That's about it for the cheap ones. The rest are $500 to $1500.Comment

Man the prices in Fisher are crazy. I was looking at a melting point apperatus the other day. I figured they'd be around $40-$50....When I looked on their web sight it was more like $4000-$5000! I couldn't believe it.Comment

I don't think $155 is too bad though for a balance accurate to 0.01g.Comment

I bought mine for less tha 100e. And i don't think that those plates pending need any balancing before use cause they are always balanced when they are empty. Old stuff is the best....Comment

I think you may have misunderstood. Who said anything about balancing anything?
Technically, a balance is the instrument used to measure MASS. A scale is used to measure WEIGHT (mass x gravity).
On a balance, gravity cancels out since gravity is the same on either side and a true measure of mass is obtained. Think of two people of equal weight on a see-saw. Gravity acts on both people equally and is canceled out, leaving both people "suspended" with their feet off the ground.
I quoted prices for analytical balances from the Fischer catalog; that's all.
How precise is your scale that you got for 100e and what is an "e"? Is it a Euro? What does that come to in dollars?Comment
