Purity - Testing cocaine purity via melting point / temperature methods

[white_lighter]

yea i was watching blow for the 90th time and i was wondering what is that lil thing that they dont show that he puts the coc on to find out what the temp it melts at cause somone told me it was called a hotbox but when i looked it up on the net nothing came up so i wanted to know if there was any othere names or does anyone know a good place (on the net) i could get one

[white_lighter]

yea i found somthing im not sure if it is it but it looks damn closethere called digital hot plates theres all kinds and some cost from 89 to almost a thousand dollers but im sure they will do the trick





lol looks like i answerd my own question

[dan46]

It's jsut a melt point tester


they used to sell them in the 80's and 90's when coke was big for about 100 bucks


nowadays forget finding one I guess but a thiele tube setup is just as accurate an cheap to setup and/ or buy in a set


all it is is a thermomether and the thile tubeand atiny epitheraial tube to attach the coke sample to for a test for melt point


all in all with a stand about 30 bucks maybe


see "the cocaine handbook" for setup info or ANY organic lab setup tezt on how to setup a melt test setup with thiele tube


easy as hell


faster isto use different solvents to do a quick wash of the unknown substance to see what it is and about how pure it is--easy to do in a situation where speed and quickness is necessary

I dont do anything illegal and you should not either


take care

digital hot plate is what you need, learn how to use it first b4 purchasing....www.google.com will help how to operate.....oh yea, you did answer your own question.....try to get the same results for 30 dollars....what a joke i dont understand why people who are ignorant answer others questions here.......sad but true

[fearmegod]

Just a little curious about this. I personally Have tries searching
google for about the last hour. I have put several different keyword
combinations. Couldn't find anything supporting the methods they use in
the movie. In the movie they heat up the cocaine and what temp it melts
away at indicates the potency. Since I couldn't find anything on it,
and am stumped, it is really baffling me! Anyone around here
enlightened in that field?

well... it quite possiably can be.. i man.... the idea behind it is
solid.. cocaine should burn at a higher temp then its cutting material.
so if it started to melt at 100 which most material does it must be cut
with something,

Pure Cocaine Hcl has a melting point of 195°C. Which means of you test yourgear and it has a melting point close to 195°C you're good . One could also test solubility.


This is taken from the Merck Index:


Derivative Type: Hydrochloride
Additional Names: Cocaine muriate
Molecular Formula: C17H21NO4.HCl
Molecular Weight: 339.82.
Percent Composition: C 60.09%, H 6.53%, N 4.12%, O 18.83%, Cl 10.43%


Properties: Crystals, granules, or powder; saline, slightly bitter taste; numbs tongue and lips. mp ~195°. [a]D -72° (c = 2 in aq soln pH 4.5). One gram dissolves in 0.4 ml water; 3.2 ml cold, 2 ml hot alcohol; 12.5 ml chloroform. Also sol in glycerol, acetone. Insol in ether or oils. Avoid heat in preparing soln as it decomposes. Preserve in well-closed, light-resistant containers.


Melting point: mp ~195°


Optical Rotation: [a]D -72° (c = 2 in aq soln pH 4.5)

Even the machine they used in the movie is real. All I know is what I saw in the movies

[pokergod0588]

is it possible to improve potency by taking it up to about 120-150Cand then dabbing out the liquid or something?

[quinone]

Whenever I have tested the purity of something using its melting
temperture (often used in organic chemistry) its done through a very
small quantity of product in a small capillary tube. I dont think
in the case of cocaine you would have enough in the capillary to make
it worthwhile dabbing out the liquid. And I wouldnt recomend
trying to heat lots of it above 120C, thatd be hard imho.

[Benga]

the whole procedure is described in Gottlieb's 70'sbook on cocaine :


"the pleasures of cocaine"

If one was just to test the melting point for coke, could the cutter
not just use a subsatnce of higher melting point? How could this
prove puriety?

[pinkfloyd2048]

The principle behind melting points is that pure substances have a narrow melting point whereas impure substances will have a range of more than 5 degree (opinion). There is no such thing as a single melting point because you have to watch the substance form the first liquid drop, the watch for the whole substance to melt. If your substance starts to melt at 193 and ends at 195, you have a pretty pure substance. However, if the range is 188-195, then there exist some impurity.


A low melting point will result from a contaminant with a lower melting point than the compound in question. Low melting points are much more common, for ionic compounds tend to be the source of high meltemps.

[scitech]

Alright, lets reclarify some things here



A pure substance will ALWAYS melt at a higher temperature then
something with impurities: its known as the fluxing effect(maybe, its
been a while since SWIM has been in college). Pure coke will melt at
around 195, even a small amount of impurities will send the melting
point faaar down



BTW, your looking for a Mel-Temp if you have enough to warrent testing
it. Not sure how much they cost these days, but basically its a heating
block with space for a thermometer and capillary tubes, and a lens so
you can see when the shit melts

What would happen if the coke was cut with something with a higher melting point? Say you find a substance with a melting point of 230 degrees? Would you just have to watch for anything left after the temp. exceeds 195?

[Urban]

... so does that mean that you could in theory "melt" the crap out of swiys cocaine before snorting it.................... therefore avoiding nasty cutting substances!?!

[Ant-Man]

SWIMS insight.......The theory of melting coke was based on the mid 70's thru mid 80's when a person could still get relatively pure cocaine. Cut was still up and comming, as they say. Pure, or almost pure, cocaine is a thing of the past (There is a response under OD'ing, however, which sheds some insight on the REAL potency of almost pure coke) therefore a quick and possibly less destructive method of doing a quick check is drop a small rock into a teaspoon with a tiny amount of water in it. Mix the rock into the water until desolved and wait a couple of minutes. 99% of the time you will see sediment develop on the bottom of the spoon, which represents the "Relative" amount of Cut vers Coke ratio.
Forgive SWIMS spelling....he's working on day four (4) of a truely extensive out of body experience

P.S. Don't do that Urban, you'll fuck up your product!!!

thanks!!!! swim wouldn't want to waste any blow!!!

[garbled]

SWIM used to put a small amount in a spoon, add enough water to liquify and then hold a lighter under it. When the liquid evaporated, you could see the cocaine become a oily globule while the cut would leave a white powdery residue around the perimeter of the spoon. The larger the oily brown spot, less cut. The larger the white powdery residue, more cut. Not scientific but you could tell if you had purer cocaine if you ended up with little white residue.

bleach, fill a shooter class, dump in 2 points, simple so pay attn close, cocaine is onmly caine that WONT turn orange in bleach, amphetamoines, turn red, coke forms a slow milky trail that slowly falls like snow, anyinactive filler just sort of clumps white at top or bottom but DOES NOT fall in a milky snowy trail, THIS IS THE STANDARD METHOD WE USED WHILE BUYING KEYS IN THE DEEP SOUTH (PANAMA,COSTA RICA).There is no better way, you can tell roughly by the size of the red piece(hope not but today its there)and the size of the yello orange fake caines, and the milky trail and compared to the other white crud, what a damn closepercentagesof what you have, Im sure some guy will say Im wrong but when I was there and did that (more than once) everyone was suingthis method, guys filling boats, planes, or a napsac, this IS THE METHOD and I dont care what 19 year old chem student who snorted 3 lines on the weekend tells me of this practice that is still un use today, no fancy machines,labs,nada!!! javex and a shooter glass.

[Woodman]

bandito,

That's interesting, but without reference to the proper proportion of coke-to-bleach ratio, as well as other more specific information, that's kind of like telling someone that they can bake a pie by just adding sugar and flour.

I can't give you a link outside the sources forum, but you might want to try entering keyword: "Cocaine purity test kit" and see what comes up.

dude, thatts te easy part, and I did tell amounts, shooter glass, 2 points, but you can use any amount, the thing is for a field buy this is grat it cant tell you there is 21 perc. novacaine as it just looks roughly 20 % of that, when in ANY SITUATION unless your a cop does it make ANY DIF AT ALL if it is 85 % or 86??? there is none, its to get a all around look the pippoints dont matter for fuck sake unless you just wanna play lab talk and bla bla bla, it is the best field analysis tool around still, bI think your just talking lab talk for the sake of lab talk on a fun topic and that being the case it wouldnot be too damn hard to make a uniform test with exacts< but only use that is when your a lab tech for the DEA, wake up here guys , reality check

[Fantasian]

A cocaine testing kit can be bought legally online just as an XTC testing kit can be bought. I've no experience with it's effectiveness and neither has SWIM but a search on google will produce it.

[rmoon0123]

So I've read through a lot of stickies and threads. Can't seem to find the answer to this though. I see that obviously the best way to test the purity of SWIM's cocaine is a hot plate. SWIM has a hot plate but it's temperature knob is just a 1-10. How is an effective way to test the temperature of SWIM's hot plate to know the temp.


Also....SWIM see's that the melting point of pure cocaine is 195 degrees celsius, but what would "good product" start melting at? In other words, what the minimum melting temperature SWIM would want to buy stuff at?

Thanks
