☛ Official ☚ The Big & Dandy Scale / Balance Thread - Part 2.000±

Put a piece of paper or a gel cap on it so you can fit the necessary amount of material.

Most gel caps weigh ~.1g (100mg) if I'm not mistaken. Do not tare as this decreases accuracy just do the math your self.

I do this every time no matter what I'm weighing because it's easier than putting powder right on the scale itself.
 
Hey all, I'm at the point now where it's inevitable that I'll buy a milligram scale for some purpose or other (be it RCs or not). I never buy the cheap stuff (you get what you pay for IMO), so I've basically narrowed it down after reading most of this thread and some others at other forums, and have it pretty much set that an Acculab VIC-123.1 is a good scale for the purpose of measuring out tiny amounts of material.

That said, is it possible to work around the +/-.002g repeatability by simply calibrating it before every use? Is the linearity of +/-.003g an issue? Since RCs scale very quickly in such tiny amounts, it's obviously important that the scale be as accurate as possible in its sensing range. And finally, is there any reason not to buy the above scale on eBay, where it's a bit cheaper? I'm always a bit wary of getting a crappy clone when I buy on eBay, even when the product is described exactly as it is on the manufacturer's site. Thanks for the help!

Yes that should work but i dont think its absolutely necesary calibrate before every use. especially with a good scale. Try recalibrating once a month or every couple weeks depending on how often you use it.
I would get a scale accurate to 1mg or 2mg for better accuracy. 3mg is to wide a margin when dealing with RC's especially really dose sensitive ones.

ebay has worked fine for me.
 
I take it no one has thought of just measuring out a large amount of RC and then cutting it up?
 
^Of course people have thought of that.

That's not a good/safe way to do it. You must use liquid measurement to make sure that your actually dividing it into equal amounts.

If you do it by eye some piles will definitely be heavier than others even if they look the same.
 
I've got a problem with my Gempro-250.

If I put a Rizla paper on the scale it weights it out to 49mg. after a few seconds it starts to go down. 48mg, 47mg, 46mg and so on. There is maybe 15-20seconds between each number.

It's strange. I've just bought it, so maybe i'm just doing something wrong.

any help is welcome..

I've got a Gempro-250 which has worked perfect for me. Every now and then if I leave a weight on, the scale will register it as lower and lower like you mention. The initial reading is accurate, but after you've left the same weight on the scale it begins to register it as a less accurate smaller amount.

To get an accurate reading, turn your scale on, calibrate the scale, make sure the 20g weight reads as 20.000, (sometimes its 20.001 or 19.999 which isn't a HUGE deal, but try to calibrate it to 20.000). After the scale is calibrated I put a "OO" gel cap on the scale which weighs around .090, but sometimes between .088-.092 and then I note what the weight of the gel plus the weight of what I want to dose out is combined. If the gel weighs .091 and I want 25 mg of material, I note that I want the gel to weigh .091 plus .025 = .116, or 116 mg. I then use a straw with a diagonal cut on one end. I use the diagonally cut end as a scoop to scoop material and dump the material into the gel cap. Once I have capped the gel cap I weigh it out by placing the gel slowly on to the scale. I will then weigh the gel out a few times in a row just to make sure the scale is giving me an accurate reading each time. If the gel weighs 116 mg then I have 25 mg of material, if it weighs 120 mg, I must dump some out and continue weighing the gel until the total of the gel and the material weighs 0.116.

Don't leave the weight on for extended periods of time, when properly calibrated the scale registers the correct weight weight within 5 seconds.
 
read the posts above you?

if you are weighing out a single dose, use a gelcap or folded card instead of or inside the main weighing pan. the pan is useful for larger amounts if you are doing liquid measurement.
 
I ordered the American Weigh DIA-20 since I had read the good reviews in here about its predecessor the DIA-10. It works like a charm for the price. Just weighing the tray by itself, then weighing the tray plus the product and then subtracting the the tray weight gives you damn close to the amount you actually have. It can't be beat for the price.
 
so I have the cheap $24ish AWS DIA-20. It seems I have to constantly calibrate it and do so several times and then warm it up by weighing the 10g weights several times before it is in +/.003ish where I am comfortable. It seems to be pretty accurate or at least well enough when you go above .020 but below .010 it is really iffy. I have found that once I calibrate it and then re-weight a 10g weight and it reads within a few mg of a 10g weigh that it is much mroe accurate once a laod is on there. so to check a weight I often add the 10g cylinder and then see if the difference is the same or off by much. I think I trust that a bit more but still I am much more comfortable weighing 50mg and then making a known solution to store in a vial. the only problem is that isn't great for smoking the very small mg RCs like JWH-018 and 5-meo-DMT which I am getting tomorrow. So any suggestions for those where a dose is a few mg and liquid form is not a good thing?


For the 2c's I am going to get some bacteriostatic water and new vials and make solutions of 50-100mg with 5-10ml so I can calculate how many CC's on a syringe is 1mg and very accurately dose things and have them stay sterile for IM inejction.

I just don't know what to do for the smokeables.
 
^^ Use gel caps!

Calibrate your scale and test it with a calibration weight until you are content with the accuracy.

Weigh out a gel cap numerous times until you notice a consistent reading. If the gel cap weighs differently every time you weigh it, then weigh the gel cap numerous times and calculate the average.

Note the average weight of the gel cap.

If the numerous weights of the gel read between .089-.091 then the average and most probably accurate weight of the gel is .090.

If the numerous weights are drastically different than calculate each reading.

Example
1st reading = .091
2nd .088
3rd .090
4th .092
5th .091
6th .089
7th .093
8th .090
9th .088
10 .091

Add all the readings and divide by 10 and you have the average of 0.903, or for simplicity sake 0.090

If you want 5 mg of material than use a straw cut diagonally at the end into a scoop to scoop what looks like 5 mg into the gel cap and weigh it.

Weigh the gel a few times until you notice a consistent average reading. Again, if the readings are drastically different one after the other, than weigh out the gel 10 times, add all the readings and divide them to get the average.

If the gel cap consistently reads around .98 then you've added too much material and you must remove a bit of material and re-weigh it.

After removing a bit of material and re-weighing the gel cap, if it consistently weighs around .094-.096 then you have an average of most likely .005 of material.

Proceed to place in pipe and smoke!

This is about as easy to follow so there are no excuses for overdoses!

Hardly pin-point, but if your scale gives different readings consecutively for the same item, the closest to accurate you are going to get is by just weighing the gel numerous times, calculate the average and then once you've scooped some material into the gel, weigh the gel cap numerous times until what the scale reads averages out to the dose you'd like.

Be careful and weigh the gel and the dosed out gel as many times as possible!

it wont be the most accurate,
but it'll only be off by a couple mg's if any and is much safer than a .01 scale.

i have a scale accurate to .002g

what i do is put the weighing tray on first which weigh exactly 1.702g and then add the powder pf what im wighing to that weight.
So if i want 30mg of 2cb i pour untill it reads 1.732g.

this gives a more accurate reading than starting from 0.000

and be sure to recalibrate regularly to keep it most accurate.
or you can invest in calibration weights but they are very expensive.
 
cheapo china man scale...

u can look into analytical balances for real acuracey.

these cheap chinese scales do the job but are not always accurate.

The number reading on the scale isnt always the exact measurment on there.

but there are ways to use these scales efficiently.
Either by how i stated above or liquid measurment of mall amounts.
 
I almost bought one like that but decided accuracy was important. I don't trust that one to be.

Any suggestions on something under $200? As low as possible without losing quality would be nice. I'm looking to buy soon.
