RC weight and scales

[college]

Is it possible to use a non digitcal scale to weigh out stuff? The water (alcohal) method seems iffy. any help would be appreciated!!

[nanobrain]

yes, absolutely. torsion balances accurate to 1/10 of a milligram are available at significant discount from your local online auction house.

[TheLight01]

Swim just recently bought a digital pocket scale that is accurate up to 0,01 gram (10mg) and thats good enough for the 2c-x(-xx) RC's he's had.

[GDxCAT]

actually its probably not good enough because when it reads 0.01 it
could be anywhere between 10mg and 19mg. And with certain 2c's
that have steep dose response curves (2c-e, 2c-p) you may be caught off
guard by the intensity of the trip.

Be safe man. I will reiterate some wise words. If you can afford to buy RC's you can afford to buy a scale.



peace.

[nanobrain]

^^10 mg? tell me you are joking.

[TheLight01]

Its works for dividing lets say a 500mg batch op to batches of 100mg and then to batches of 50mg..


Then you can divide a 50mg batch in 6 parts to be safe.

[nanobrain]

for anyone reading, a 10 mg scale and a pair of eyeballs is in no way accurate enough to safely measure research chemicals.

[trippy420]

You should invest in a scale that is .001. I think this is as close as you can get. I is definetly worth it.

[Pinkavvy]

you can get a cheap scale for LESS then you can buy a g of your favorite rc for. you really have NO business playing with rc's (and your life, and the life of others who you may overdose) until you get a scale. <- see that, it's a period. there's no 'what if's or 'but's ... get a f'kin scale.

the next $86 you have saved for an rc purchase best go to a scale. nanobrain will come check on you, so you better get one.


p.s. the liquid dosage technique should be used as a way to storing and dosing easily. you still have to measure what you're putting in there. ya think just caues you ordered a gram means you only have a gram? lol

I think I'll make up some bumper-stickers: BUY A F!$#*$@ SCALE! YOU LAZY BASTARD!

[GETERDN]

You are going to want a scale in the long run, beleive me, any method to try and go without one is just a hassle, as they already said before i posted, you can get a good gempro or other .001 accuracy scale for pretty cheap, just look around, you will love it

[nanobrain]

^^T-Shirts to expand the bumper sticker line.

[Solidly-here]

A 2-milligram-sensitive scale is enough.


GETERDN threw-out the following: "you can get a good gempro or other .001 accuracy scale for pretty cheap." Well, a one-MG-sensitive scale is not pretty cheap. In fact, it may end up being less accurate than a "good" 2-milligram scale.


Radiometer has been on a long Campaign: Vote for a 2-milligram scale. I listened, and "voted"...and I'm glad I did. (Thank you, Radiometer.) The 2-milligram models are (on average) quite a bit cheaper. So, buy one and save.

torsion scales arent digital.


balances arent digital.


dollar for dollar balances are cheaper and more accurate, but digital scales have certain advantages as well such as variable calibration etcetera (so you can automaticly deduct the weight of a gel tab)


theres always good old fashioned thunderjuice. a half gallon of everclear will run you about 30 USD, and then all youd need is a measuring cup. this of course will not work with tryptamines, something about the two exposed nitrogens I think, they break down over time in aqueous solutions.

[GDxCAT]

my gempro 50 just stopped working.



I have had it for 1.5 years already.

i tried changing the batteries and eveything.oh well, it was a piece of shit to begin with.



A tanita is on the way.

[Nagognog2]

Tanita, according to a reliable source, has stopped making the 1210-50 and 1210-100 models, and is charging outrageous prices for parts. They seem to have decided their customers can either pay a forture or go to hell. My source for all things that balance suggests looking for other manufacturers.


If you can find a Tanita 1210-50 or 100 still at a reasonable price, it would be a good idea to pick it up now. Or forever hold your peace - and broken Gempro.

[snapper]

Found this model on the web recommended as an alternative to the
TANITA

Acculab VIC-123

Sounds like it might be comprable and the price is similar at a low of
$265.00
accurate to 0.001mg

Snapper

[Nagognog2]

Read on. Due to it's mechanism - it's not likely to be reliable in the low mg range. Someone needs to put one through it's paces with a set of calibration weights.

[GDxCAT]

yeh nag, lucky for me i found 1210-50 for just $100.



I oulkd be fine with buying a balance, as they are more accurate, but i like the idea of having a pocket scale.



Maybe when i save up enough ill get a balance accurate in ug's.

Swim is wondering which (if any) of these would be good for weighing out 2c-i powder which swim is determined in putting in capsules?

Proscale Gemological 10

10 gram capacity
.001 g resolution

$80

Or

Jennings/JScale JSVG 20
Digital Jewelry Scale

20 gram capacity
.002 g resolution

$80

or

Jennings/JScale JSVG 40
Digital Jewelry Scale

40 gram capacity
.005 g resolution

$85

Any advice would be much appreciated by swim

People should learn how to read the specs.
It's essential that the balance users have access to appropriate calibration weights. If the spec calls for M1 grade calibration weights, the weights need to be M1 grade. These analytical balances need to be turned on and left on for at least 30 min or so to stabilize and periodically calibrated.

Reading down to 0.005g means the resolution is 5mg, but linearity and accuracy is another. The rule of thumb in instrumentation is that one should have ten times the resolution of needed resolution. So, if one needs to weigh to nearest grams, the balance should be able to read to nearest tenth of a gram.

These mg scales are usually used for analysis. For mixing, it's usually better to create a larger batch, so when preparing 10mg/ml, one wouldn't try to mess with trying to weigh 10mg. One would weigh 1g on a 0.01g scale and make it 100ml to yield 10mg/ml solution.

Use ground up calcium pills or something as a filler and premix a larger quantity, so that it's easier to dose.

So is swiy saying swim needs a scale that is .0001 g to accurately be able to weigh out the powder down to the last mg? Swim is confused (and possibly a bit retarded)

Blizzard777 added 2 Minutes and 5 Seconds later...

Swim has also heard that .002 g scales have more accuracy than .001 g scales, is this true?

Swim apologizes for all the questions but he has been trying to figure these things out the past couple weeks but to no avail

SWIY needs to read the specifications and the scale needs to be calibrated to achieve the rated accuracy. If the specs are not given thoroughly, the precision and accuracy should be questioned. Cheap "GEM" scale sold primarily to the general public do not have published detailed specifications. Jewelers actually involved in weighing jewelry don't use these scales. They're required to use legal-for-trade grade balances.

Sartorius, Mettler, Ohaus, A&D, and Toledo are among the reputable balances. If one is measuring 100g of something, something that reads in the increments of 100g is not acceptable. 10g is marginal, preferebly something with resolution to 1g (100 times the resolution of amount being measured, with +/- a few digits).

If one needs to measure 10mg, then 0.1mg scale is a very good idea...

Balance should come with a means of calibration and one needs to purchase a proper grade, calibration weights and calibrate frequently.

No... it reads out to 1mg
and it is repeatable to +/- 2mg and linear to +/-3mg, as per the mfgr specs.

If you put 10mg bead on it, then it should read within 8 to 12mg every time.

Linearity is how linear the balance responds. This scale is 120g capacity, so if you were to put a 100g plate on it, zero the scale, then the same bead can read anywhere from 7 to 13mg

Acculab is decent. Certainly much better than no brand junk that comes from eBay, but it's no Mettler Toledo.
