What scale do you use?

[Chaos]

SWIM is almost done with preparations to perform his first extraction( -many thanks to this forum). SWIM has realized a good-quality scale is the biggest (and possibly most important) investment of this process and is wondering if anyone has recommendations before he blows 200 on one.

For under ~250 bucks GemPro 250 is one of the top choices

If you have more to spend, I would look into brand names like Tanita and OHAUS. Be sure to get a calibration set too.

Lab-X might have some good deals and a search over at ScienceMadness might give you exact model names.

Can someone post a link for a good milligram scale? Or a cheap one. I can't find any on amazon or ebay, all I see are gram ones, like from 100 g to .01 g

but that one doesnt say mg, it says .o1 g, how would i measure out a 50 mg dose? though i also probably need one that goes to 100 g for extraction (so i know how much mhrb i have), but i could buy 2 different scales. this is all theoretical though bc i dont have enough money yet.

0.001g it says. That is 1mg. And yeah you'll probably need two sets of scales. Mg scales typically only go to 20-25g. A set of 0.1-200g or thereabouts is ideal for weighing MHRB and NaOH.

 

[AvidGardener]

Thanks Gary heh, I actually have three for some reason. The one I posted is indeed a mg scale, besides the fact that it says it, I use it frequently . Its a good scale, but It usually needs a calibration for every use, so don't lose the 2 10g weights that come with it. I have a hook scale for weighing Cacti cuts, a .1 to 500 for weighing MHRB, Lime, and Cacti powder, and the mg scale I posted for end results.

There are already threads made about this. Use the search.

So what reading will be 50 mg? .050 g?

what chemical is NaOH? I was planning on using the dry tek that uses lime instead of lye.

What is callibration?

Sodium hydroxide.

Can anyone else vouch for that scale besides avidgardener? Not that I don't trust him, but you know how some people have good luck with these things and others don't. I really need a scale soon but I don't want to spend hundreds on a mg scale.

Horizon Pro is the same scale as the AWG which kind of "the official Nexus scale" since so many people have it.

Rule of a thumb - There are only two type of scales, those below 150-200$ and those above 150-200$.

Scales FTW.

If you want to spend moar - GemPro 250.

what do you mean its the same? same company? same parts manufacturer? what's the same about it? would it be better to just get the AWG?

 

[Tropical]

Thanks guys, probably going for gempro to try as its cheaper now just trying to find a place that is willing to ship outside the USA.

Cheers if you guys know of any others that look like they are good and accurate, please post.

 

[AvidGardener]

Calibration is making sure the scale is weighing accurately. With this one, you put a 10 gram weight when it tells you to, then another 20 gram weight on top of it. It only takes a few seconds, like I said, I do it every time I use the scale.

I dont know what the exact differences, but i would guess they are identical. Same thing with Video cards, someone takes an Nvidia card changes a few small things and calls it Xtasy brand. Its the basically the same.

i have the Gemini-20, by AWS (american weigh scales) and it looks identical to the horizon pro.

I can vouch for the AWS gemini 20. It's great for the $$. Just don't lose the calibration weights; dealing with mg's requires precision.

 

[AvidGardener]

Only difference is the stand-by weight is sticking out on the first one pictured. I have that the Horizon Pro, and it can get in the way sometimes.

 

[anrchy]

Strange, my gemini-20 has the rubber grommet and the weight sticks out like the horizon picture rather then the picture of the gemini wheres its almost flush.

 

[Garyp88]

The one where you can see the calibration weight sticking up is identical to mine and I can certainly vouch for it. It was cheap as hell and has lasted very well and appears to be very accurate. On a bored day I used it to work out the average weight of a rice crispy. If I remember right it was 24mg. I guess a good follow up experiment would be to take a handful of rice crispies, weigh them all and then divide the weight by 24... then count all the rice crispies and see how accurate my average was. I think I'll wait until I am *really* bored before doing that.
