Scales for photo chemistry?

[RalphLambrecht]

I use cup cake or confectionliners to weigh chemicals in.They are clean,cme in different sizes, work great tand you can throw them out afterwards to avoid contamination.You get them in the grocery store and,they are inexpensive too.

Why not you use known weight that most companies offer with their commercial scales. Because they are manufacturer under national standard of weight manufacturing and provide you accurate result.

most people use the toy drug dealers scales cheap rugged and most come with a calibration weight.

but people are not trusting a coin is a good secondary test.

I have three scales: A kitchen scale for 100 g up to 3000 g, then a "toy" scale for anything from 2 g to 100 g in 0,1 g accuracy, and finally a gunpowder scale for anything in really small quantities, with 0,01 g accuracy and proper wind guards etc. So far, I have only really needed to use the latter for phenidone, and I suspect when I get round to gum printing again, I'll use it for the pigments. The rest is not that critical, and in many cases it is easier to work with solutions and pipette an accurate volume rather than bother with weighing.

huh, i didn't know the digital scale ( made by toyo ) was a drug dealer's scale.
i've been using it for years (david goldfarb here on apug recommended the seller )
and it was purchased through http://balances.com/ ...
i use coffee filters. i was going to buy an ohaus but i figured as long as the digital scale
was accurate it would be precise enough to weigh out whatever i needed ( and inexpensive ).

Which model did you get? I went to their site, but couldn't find a Toyo scale? I'm using a couple of cheaper Chinese scales and they are fine for some things, but when it comes to weighing phenidone I get a little worried. JW

hi jw

i just called their phone number ..
toyo doesn't make scales anymore
i asked him what was similar in price and quality &c
and the person i spoke with suggested the "my-weigh" brand.
i'm not sure if your inexpensive chinese scales are the same thing
but there are detailed descriptions that might be helpful ( or not ) when you click on the info button ...

(sorry if i am not much help! )

good luck!

John,
I have one Chinese with wind cover and calibration weight that weighs down to 0.01g. It seems to work fine, but I check it all the time to make sure it's weighing right. I just don't know if it's worth going for a more expensive unit or not. The bad part about digital scales is that they might be off at the lighter weight and be on with the calibration weight. Non-linear I guess you'd say. Now, an analog scale shouldn't have that problem I don't think. JW

Another vote for Ohaus triple-beam balance. For what I have spent on cheap digital scales that last only a short time, I could have nearly bought an Ohaus and given it to my son decades from now.

Yet another vote for the Ohaus triple beam. I got mine at a police auction.
