Gemini mg scale problem
#21793692 - 06/11/15 04:18 PM (8 years, 7 months ago) |

I measured the mass of a quarter, and it came out to be 5.666 grams. I did it again, and it was 5.673 grams. I looked it up and the actual mass is 5.670. Is this just from the abnormalities of the quarter, or is my scale calibrated improperly? I want this to be as accurate as possible, because I'm going to be measuring etizolam powder, and as I'm sure many of you know, the difference between 2mg of etiz, and 6mg of etiz, is HUGE

Why don't you recalibrate it just to be on the safe side, but I've noticed cheap scales tend to give different readings like that. How are the batteries?

Ok will do. Just have to finish reading how to do it in the manuel. The batteries are the standard triple A's it came with. I'll switch out to duracell

Don't measure single doses of etizolam if it's a gemeni-20

Remove the batteries every time you turn it off because leaving them in sucks the battery out. Also calibrate before every use.

apparently you have to tare the scale with some weight on it already. So put the quarter on, tare it, then weigh the etiz

You better put it into solution like people are telling you. Those scales are not accurate when weighing really small amounts the manufacturer even says +/- 5mg or whatever and +/-5mg of etiz can mean you waking up in jail

That scale does that. I used to have the same scale until I lost it. I'd never way out a single dose of etizolam because that scale isn't good enough for that. The best thing you can do is put a decent weight on it already. Example:
Get a piece of tin foil to use as a weigh boat. Place the quarter on the scale, then place the tin foil on the scale. I wouldn't even tare it. Just remember how much that weight is. Then weigh your substance very incrementally. The Gemini scale won't pick up weight until you go to like 5mg or so. I'd weigh out 10mg then you can divide that evenly. This is really sketchy though and I never did this. I'd just weigh out my entire batch and then mix it with everclear. You can also use 99% ISOPROPYL alcohol drip it onto something and let it evaporate.

You should recalibrate it, use the tray as the tare weight, and then mix a bunch of etizolam into a solution.

You absolutely do not weigh single doses of etizolam
You weigh out your total, say 100mg. It reads .102g. You know that there is a +-2mg error, so it could be anywhere from 100-104mg. Then, you add that to 100ml Propylene Glycol (PG), Glycerin, or 190-proof ethanol (Everclear, Gemclear etc.). And that's it, you now have an etizolam solution at 1-1.04mg/ml.

I have this same scale, and while it's not perfect, I think under the right conditions it can be more accurate than this.
It definitely needs some more weight on it. It is much more stable that way. I use a penny usually, any coin will work, as long as it's not too big or heavy for the scale. I'm sure a quarter is fine. It might even be more stable at higher load, I'm not sure. But without the extra weight, the thing will jump around all over. Whether you tare or not, I don't know if it matters, but I like to tare, because I don't have to do any math . I think it works just as well if you tare it.
You need to make sure you're not in a room with any draft whatsoever. Windows and doors closed, heater/ac/fans off. If you even have people in the room moving around it will throw it off. Be very still, have it on a level and flat surface, and don't breathe on it. Make a point of breathing away from it, because your breath will throw it off. Waving your hand around near it will throw it off. Anything will. After you power it up, add your coin for extra weight, then sit there and let it settle down for a sec. It will jump around a bit at first but then it will settle down and stick to one number, so long as there is not too much air moving around to throw it off. If you are in the perfect environment, I think this scale is good down to a few mg... 2 or 3 maybe at best. I use it to weigh doses of 4-aco-dmt and so far so good. I think anything more potent than that though, would be a bad idea.

Well technically speaking, you took 2 measurements and the average was 5.670. Your scale is accurate, its just not precise

I guarentee you if you had the most accurate scale ever no coins would even be close to eachother in weight.
I have coins that are a whole point different in weight.
They go through so much wear and tear, there's no way every coin weighs that, that has to be either the weight upon production, or the weight average.

plus there is a small tolerance in making coins that arent based on the value of the metal theyre made of
