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

good morning fellow BL'ers.

soo..... after trawling through so many pages all over the net, ive come to the conclusion that there aint no such fuckin thing as a truly accurate scale that doesnt cost thousands of dollars.

My question is, in your opinion, what is a good scale under $200 that can be trusted to weigh out 2C-E?

i was hoping to go with the AMW GEMINI PRO, but judging by some things ive read, that simply aint gonna cut it?

any help is greatly appreciated, as im on the edge of tearing my hair out cos im sitting on 2g's of this stuff and im getting tired of trying to find reliable scales.

as for the GEMINI, how innaccurate are they? is it possible to weigh out say, 20mg ACCURATELY, and then proceed to use liquid measurement to dose at least somewhat reliably?
 
Alc-80.4

ALC-80.4 is a analytical balance capable of weighing sub-mg amounts. You can google it if you like to see what it's about. In my limited research it is the cheapest analytical balance that does what I need.

Does anyone have experience with sub-mg dosing using an analytical balance?

Truly accurate? That doesn't really exist. As long as you have the means to measure more accurately you will come across more decimals ad infinitum. What matters is significance of numbers and that can definitely be found for a steal.

I have a lab scale for more than 200$ (150E) and it can only weigh 0.005g accurate but does a hell of a job, it is also sturdy and large, checks if its level and has a complete plastic dome and large plateau.
I also have a cheapass thing that was the most expensive 0.001g scale dealextreme in asia has and it was still only 27$ including shipping. The casing feels weak but the electronics and mechanism seem sweet. It NEVER creeps near zero nor does it creep at bigger masses, calibration is not at a 100% when I use the calibration weight but very very close, it is consistent, and I absolutely never had an instance where I had an unexpected result with anything, period.

What the hell are you weighing that is so potent? If it is active around 1 mg then a 0.001g scale never cuts it even it is a super decent device, I hope that is evident? Yes weigh as much as you possibly can for liquid measurement and continue from there, it increases your accuracy with a factor of the number of doses you start out with weighing times the change in accuracy going from mass to volume. (correct me if I'm wrong)

Say you weigh 70 mg of a compound with 1 mg doses and put it in 70 ml of solvent, but you also have a plastic syringe that can measure 0.1 ml then you win 700x accuracy. And add to that you can see 0.1 ml in an analogue way as opposed to the discreet steps of a digital scale. I dissolved alprazolam powder in vodka or ethanol this way and it was perfect.

No, but I have in the laboratory. You better close all doors and windows to prevent any draft, and do not make sudden movements near the scale especially with your whole body like walking past it. It will create a turbulence in the air that disturbs your measurement.
The plastic dome I mentioned earlier is designed especially for this.

Hi,
If anyone knows of a Canadian Company, or any company that will ship the Gempro 250 (or a scale of equivalent quality and price) to Cananda, I would really appreciate it. Im having real trouble finding one here -
Cheers
 
^ Don't use saveonscales.

It took them about a month to send it and their customer service wasn't the best. My credit card wouldn't work because I didn't put the middle initial or something like that and my funds were held for multiple days on about 4 separate occasions before I was able to get the payment to go through. There are a lot of places that ship to Canada, just find any basically US based website. A few websites have been mentioned in this thread but it will take some digging. Maybe someone will pipe up with a suggestion but the only suggestion I can give you is to not use saveonscales.
 
Hi,
Thanks any major dude - I have settled on the GEMPRO 250 - A couple important questions before I order though:
It allows for Pre-Calibration, Sensitivity-Calibration, and Linear-Calibration, however it includes only one calibration weight.
Should I get other weights while Im about it... if so which ones? To be honest I dont even understand those different types of calibration, but Id like to be as accurate as possible, and I can figure them out if necessary.
Thanks,
Headlight
 
Today I bought a mg scale, and I have few questions about it. My scale is Sima Scales 20x0.001. I live in different part of world. I don't have much money, and I need scales quickly, so I bought these for 70$.

They come with 10g calibration weight. BUT even after re-calibration this 10g was weighted as 9.78-10.10. Such measurements scared me, but maybe I just impoperly placed my scale. However even when I tried to be very accurate, my 10g weight was measured as 9.994-10.002.

They also come with small bowl, which is quite handy. After I got used to scales, I tried weightening it, and it was ~2.628 g. I repeated measurements multiple times switching scale on/off, and they all was in range 2.627g - 2.629g. This is totally ok and, then I decided to measure some powder, and as it was VERY sticky, I had to repeat my measurements. They also seem to be alright, when I added powder, the measured weight increased(no tare function was used). And repeated measurements resulted in the same amount(+-0.001mg).

So, my questions. Why measurements of calibration weight was so dispersed, whereas smaller weight seem to be measured correctly? Can placing scales not totally horizontally affect measurements?
And finally, can I trust these scales? What kind of testing can I perform to check them?
 
You bet that scales not being level can affect repeat measurements! Also, these scales are never completely accurate, it's why we report measurements in the lab with confidence values :)

It seems like you should be able to trust them to about 5mg (on the safe side).
 
Ok, thank you.
Now, when I get used to them, they always give me +-2 mg, but I am not sure if I can trust them.
 
I'm trying to buy the proscale_precision_10 but the only site i can find it on, saveonscales, is not working. (The site comes up but the shopping cart doesn't work and they do not respond to my emails.) I could buy a random scale off ebay but don't know how good it would be. This scale gets good reviews so I feel better about buying it. Anyone know of another source?
 
Anyone mention that some scales suck because of their stupid design?

I have two mg scales. Under the weighing platform there are prongs that rest it onto the scale so it can be level to get a true reading. I have one scale that uses 4 prongs and another that uses 2 prongs. I NEVER used the two prong scale and will probably give it away because it is very inaccurate.

American Weigh DIA-20 is the two prong scale.

MyWeigh Gem Pro 50 is the 4 prong scale and works very well.
 
I have one of those cheap 20g 0.001g precision scale, and while trying to weight a 10mg piece, I have readings of 7mg to 14mg depending on the plate, if I put a coin under the plate, tare it, I get a 12-14mg reading, if I use only the plate, 8-10mg... I'm not sure what can I do to improve the precision... Buying another is out of question, no money...

I'm trying to weight 2C-E... I was thinking maybe if I mix it with some powder, preferrably snortable inert powder I could improve the measurement, but I'm not sure if the powders will mix homogeneously, have anyone tried this or know any info about it?
 
i have had success with homogenizing 2C-I and a (relatively) inert powder like sugar or piracetam for easy stuffing of gelatin capsules. but not for snorting. and you don't mix before weighing. you weigh a large amount (500mg) then mix it with a weighed amount (20g) of filler and then blend for 2 minutes in coffee grinder. results in a homogenized powder that can be evenly packed into capsules. or course, you have to know exactly how much powder fits into each capsule, so you have to calibrate your method with your capsule machine.

Yes it's from china

anyone have any experience with this sonuvubitch? ^^^^^^

That is an American Weigh Gemini-20. I have one. It's actually not bad; however, if you're weighing really small amounts (sub 20 mg), I'd highly recommend weighing 5 or more batches at a time and then dissolving in a known quantity of water to reduce measurement error.

As a portable scale, the Gemini-20 is worthwhile.
 
Anyone know anything about the HA-20 Digital Scales 0.001g or the AMPUT APTP449.
I know neither will be the best of the best, but I don't fancy spending £2-300 on a high grade set.
 
I have amput aptp449 30gx0.001g

This set is a major battery hog, tends to drift A LOT if the batteries are even slightly discharged, ac power unit is absolutely essential.
They are fairly accurate (definitely a lot more so than 20$ HK scales) but only if re-calibrated frequently. Sturdy enough too, served me well for almost a year.

I use the DIA-20 regularly and it is accurate within 5mg, though I have used them to be even more precise than this. Simply using a level platform in a room with a constant pressure greatly helps. Calibrating before every use is very helpful as well, as is weighing multiple times. For ~$20, it is not bad.
