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

I have a second hand 10ug balance and have found it to be nothing but reliable, even having been sent in the mail (albeit well packed and by courier)
 
How much am I going to have to spend to weigh at ~10mg I can have +/- 2mg

~ $70-80 USD.

Get the js-vg 20.

Solid build quality, very sensitive, stays in calibration and comes calibrated, also easy to calibrate. :)

2mg resolution up to 20,000mg, i use it over my two cheap $20 mg Gemini scales, because i know I'll get a more accurate reading even if the resolution is 2mg vs 1mg. Lots of drift with Gemini's, and all the other generic $20 mg scales that are widely distributed. Don't buy anything from deal-extreme, or any of the many copy's of the AMW Gemini 20, or that scale itself. You get what you pay for.

IMHO, its worth it just for the quality alone, Gemini's and the like are nice and all, but side by side you can see where the extra $ gets you a far superior scale in terms of design/build quality/durability.

And there's this as well-

20 YEAR MANUFACTURER'S WARRANTY!

If ya have a problem with this scale within the first twenty years ya own it, just send it to the Jennings warranty center right here in the USA. They'll fix or replace your scale, and have it on its way back to ya within two working days.

Which is pretty nice =D

And if its for 2c-x's, i'd go with liquid dosing in sterile water (boil distilled water in the food-safe plastic, airtight container you'll be storing the solution in. Mix it up in ~5 dose amounts at a time, and you'll get 5x more accurate doses, and 2c-x's are fairly stable. Store the plastic container/vial in the freezer and it should last for years with phenethylamines like 2c-x's. Wouldn't do that with tryptamines unless it will be used within 3months to preserve potency/prevent degradation.

Do it like that, and with a 5mg drift on your scale of a 50mg substance (2c-e lets say), your getting +/- 1mg max per dose (assuming 10mg doses, dosed from a solution volumetrically, IE luerlock 3ml dosing syringe).
 
I disagree. I think $15 is fine to weigh 10mg if you're happy to have 2mg error, since that probably means you can weigh 20mg and spilt it easily. Not good enough for single doses of 2Cs really though.

I always insuffilate 2c-x so a regular dose for me is 10-20mg

I used to have a good one that broke but I did not buy it personally and It's a couple hundred new, would the cheap $20 amazon scale, or the DIA20 work? If not i'll probably try to get the js-vg
 
I always recommend the Gemini-20 set for people on a budget.


The DIA20 (left) are very similar (likely identical inside) to a set which I got (right) which left me wishing I had spent the extra few bucks for the gemini-20 scales I used to have. I would avoid them.

I got the Gemini-20, would it be better to do 10mg measurements or 20mg then eyeballing it into two doses?

When I measure below 15mg, I would turn on the scale without the tray, put the tray on, but don't tare it, then weigh from that. A bit more math is required, but I think it's better than just starting from 0 with such small amounts.

Alright i'll do that, thanks for the tip.

Sound advice. I and many others have found that holds true for not just the gemini, but many milligram range scales. I weigh everything that way now. And sooner or later, you can derive an average of the trays mass, and after letting the scale warm up, if the tray doesn't way what it normally does, your drifting or out of calibration.

Almost every time my scales get out of calibration, i knew because i have a tray i've used for a few years now, across a few different scales. It weighs somewhere between 2.500g and 2.502g, and came with my aws gemini. I have a identical tray from my 2nd gemini that weighs ~ 2.452g-2.454g. If they arent in that range after the scale warms up, i know somethings up and i need to reset the scale, check the voltage of the batteries, or bust out the 10 & 20g calibration weights i have, and do a recalibration.
 
What are the main differences between a balance and a scale?

Hypothetically if I am measuring out between 10-150mg, surely any scale/balance with a .001g resolution should suffice?

I realize that the other variable here is actual accuracy.. sure it may give me +/- 1mg, but if its only accurate in a certain range then at 10mg I may have something entirely different? No such variable is mentioned. Im going to sift through the threads but if someone could just give me a one up here that'd be cool. I don't want to go exceptionally cheap, but I also don't want to spend nearly 200 (which I realize is PEANUTS) when a $50 scale will do me just fine..
 
I can speak for the gemini-20, I've had a set for 2 years now. They're still as good as the day I bought them and they've been through a battering, I've never even had to calibrate them.

You can get them from DealExtreme for $21.40 (£13.66) with free delivery, the same ones cost £50 on Amazon. I've never owned scales other than these so I cant compare them to more expensive models but these work fine up to at least 2mg, I've weighed 2cb and other low dose substances safely on them and the calibration weight always weighed what it should until it got lost.

Big tip to anyone who owns these scales! If the weight starts jumping or creeping up when you try to weigh anything then it probably means the little platform has been nudged out of place slightly. To fix it just use your finger and push it down slightly and try to centre it. Do it when the scales are on so you can make sure you don't put to much pressure on them.
Mine have only done this once but from reading reviews it seems its happened to a few people. When it happened to me I thought it was the end of them but they're still going strong 8 months later :)
 
i have a visa giftcard with around 60 dollar on it, can anyone point me to some good scale for that price with free shipping?
was thinking of ordering from dealextreme but can buy from other places too!
 
As has been said many times, the gemini 20 or any knockoffs of it are excellent for about $20
 
Hello.

I'm looking for a balance with high precision, accuracy and repeatability to the best extent possible ($2-300). I wouldn't want an error or more than 10% at 10 mg. I am willing to spend extra money for certified calibration weights and expect to do so.

80-90% of weighing will be done between 1 and 7 g (mushrooms), the remaining will be between 5 and 40 mg. Everything tends to get preweighed and placed in marked centrifuge tubes for storage.

Ideally I'd like a balance with a windshield and a level, but can accept that might not happen.

I'm looking at http://www.amazon.ca/AWS-GeminiPRO-...id=1372785765&sr=8-4&keywords=milligram+scale

but this in my opinion is not good enough.

thanks for any pointers.

Tom
 
I think the best youll find in that range is something like this: http://www.oldwillknottscales.com/my-weigh-gempro-250.html

From what I've gathered in this thread don't think you're going to find something with that low of an error at 10mg (10% is 1mg, and in all likelyhood it seems that at that low of a weight an error of +/-2mg seems more common) without shelling out on a full out analytical balance, but itd be pretty close.

I had considered this scale actually, but went with the gemini-20 simply because it was cheap and isnt that far off as far as repeatability. its definitely not going to be 'accurate' down to 10% but I plan to measure out quantities of 40mg+ or more at a time and then split them with volumetric dosing down to smaller quantities.
