Hello everyone, Nick Tennant here. I'm very proud today to present you another Precision
product - our new CRC color remediation and chromatography column. It does a lot of different
features, like variable media, and I want to show you some of the key aspects of how we designed
this particular piece of equipment. So the first thing that you're going to notice is you've got
two very big columns in the back here and that's because these are surge tanks. You need to surge
your solvent off of your material in a very quick, rapid manner. We don't want to leave our solvent
soaking on our material for a long period of time, typically with a hydrocarbon that can be as short
as three to seven minutes, and what we need to do is get that solvent off of that material so it
doesn't pick up undesirables. So what we do with this column is we put this on the back end of for
example a hydrocarbon system and we're surging that solvent off into the surge tanks - and
that's exactly what they do. Everything on this apparatus is obviously jacketed, everything
can be controlled, everything can be metered, and you see that with the variety of features
here - but that's one of the first features that really is setting apart this particular
chromatography and color remediation column from anybody else. So once you surge your solvent
into these surge tanks, what you're going to do is you're slowly going to feed it out and you're
going to do it at a metered rate. That's going to come out and it's going to come up through here
and be fed into your actual chromatography column. Now this is where you're going to hold your media,
this unit can hold a variety of different media. And anybody that's ever worked with
chromatography or has ever worked with any sort of remediation you know that it's almost
infinite what you can put in this column in terms of blends and different medias. And we're going to
look at some of those later in the video and I'll explain some of the science behind why
it works the way it does. But the important part is you have a nice large volume of media that you
can put in here, more than adequate for your surge tank, you can meter, you can control the
pressure. This whole unit is rated up to 350 PSI. So if you want to experiment with temperatures,
if you want to experiment with resonance times through your media, if you want to experiment
with higher pressures or back charging nitrogen (the units equipped to back charge nitrogen),
you get that higher pressure that higher penetration into the media. This unit can
do all that. Obviously when you look overall at the craftsmanship, something we're very proud of
obviously, you've got the the stand that's been beautifully powder coated. You've got everything
made out of beautiful American stainless steel. The unit you can see it has all the
junctions and fittings are either compression or they are sanitary clamp, tri-clamp they call that,
and all the valves everything is rated as cleanable - which makes it GMP-ready. Which is
fantastic for anybody that's in the hemp market, anybody that's looking towards cGMP compliance,
anybody that wants a traceable product and all the paperwork, operating manuals obviously, are all up
to GMP standards - in terms of the IQ, the OQ, the material certifications, so that's outstanding.
Some of the other key features of this unit, you know you you can see obviously here the quick
releases makes it easy to take off your columns, easy to disassemble, easy to make adjustments,
easy to clean. Everything is hard piped that obviously eliminates any issues of contamination,
it eliminates any issues of the flexible hosing getting in the way, any issues of
exterior contamination from any sort of medias, or any sort of dust or anything in the lab.
So ultimately you know when you're looking at this unit it's a ready turn-key GMP ultra-clean unit
that can refine these contaminants out of your extract. So let's talk about the science behind
why this unit works, why it's relevant, and what we're really trying to accomplish with it.
So when we extract from a cannabis or hemp plant we're trying to pull out the cannabinoids,
the terpenoids, or the terpenes, and we want to extract those in the most purified fashion
possible. But what happens is sometimes we get contamination, sometimes we get mold,
sometimes we get mildew, sometimes we get pesticides, sometimes we get heavy metals,
sometimes it's just degraded biomass that's been oxidized that we want to remove things
like Pheophytin and things that are providing discoloration or contributing to discoloration
or a low quality product. And the way that we do that is we do it through selective medias.
So there's a variety of different medias you can use and the universe is like infinite in terms of
the media's you can use. Some of these medias that you may be familiar with, or maybe not,
they could be things like chinit, could be diatomaceous earth, they can be different types of
sands, different types of silicas, different types of carbons, they can be blends of any of those.
They can be different types of preparations of any of those different densities, different pressures.
So all of these things kind of come together to create this wide, wide variety of different media
that you can put into this apparatus to achieve a desired outcome. So maybe I'm somebody that
is in California and my neighbor sprayed a pesticide that's coming over into my field
and now my crop is contaminated. Well when you extract that, obviously this
myclobutanil, or whatever it is, it could be avid, it could be any of these pesticides - it's coming
with that extraction. Ultimately, it needs to be removed by a device like this. So what we've done
at Precision is really spend a lot of time in R&D developing our tech behind this. Developing
uses of the media that can go in this, so we've got a great SOP for pesticides,
we've got a great SOP for color remediation, we've got a great SOP for heavy metals,
and we continue to expand this knowledge in this database so clients that purchased this product
were able to get them these new proprietary medias and proprietary media blends along with the SOP
to achieve these desired results. Which is outstanding. It provides a very,
very streamlined way for our clients to create a very desirable end product from almost any kind of
biomass under the sun, which is outstanding. So let's take a look at some of the medias
generally, so you get an idea of what they look like, what we use, how we think about them.
I'll give you a close-up of some of this stuff, so let's take a look at some of these medias and
have a little explanation around them so you have a better understanding of really what
we're doing from a scientific level here. So obviously one of the most ubiquitous,
generally-used adsorbents is activated carbon, and you can really just see it's just black. It's like
a black powdery substance, and the surface area of what's in this right here - this is
about 100 milliliters. This is probably about 25 football fields of surface area and it's because
the activated carbon has a very porous surface right, so you have all these different molecules
that can be trapped in there all these different constituents of that miscella that can be trapped
in here. And really what happens is all these different medias that we're going to show you
have different pore sizes, they have different affinities for different molecules, and that's
ultimately the science behind it. So this may take out something really, really, really good,
this may take out something really, really, really, good - but they won't do the same thing.
So let's look at some of these medias even up close. So here we have a different type of media
and this is one of our proprietary blends. This is a mix of coral sands with some other things
that are impregnated into it that I can't talk about on camera, but this does a really, really,
amazing job. I'm going to show you some samples of what we were able to remediate color wise
and still get a very, very stable cannabinoid profile and terpenoid profile. But if we look
at this - almost looks like sand on the beach and it effectively kind of is - right? I mean that's
coral sand to some degree. So actually what this is,
is coral reefs that have washed ashore and they've degraded over thousands and thousands
of years and those coral reefs have a capacity to adsorb certain components and they may absorb
certain things out of our miscella that is undesirable. For example pesticides, for example
color, things like heavy metals - all these different things that we want to remove
we just have to find the right lock and key. And when we talk about extraction, and you've
watched some of my other videos, we talked about the lock and key methodology or the lock and key
sort of way of thinking about how to isolate these molecules, and that's exactly what we're
doing with these medias. We're just doing it after extraction. So lock and key with the solvent is to
get it out of the plant, now how do we get the desired molecules from the oil to a purified
fashion without any adulterants. So I'll show you another media here. So this one is actually
chitin, or some types of the impregnated versions are called chitosan, and what this is is actually
from crustaceans. This is from shrimp shells, lobster shells, crab shells. This is actually
crushed crab shell and they actually impregnate it with some other things. Sometimes you'll find
impregnated medias that are impregnated with silica or activated carbon,
or things like that right. So all these medias, they're all throughout the earth they can blend
something like this with diatomaceous earth, you blend it with activated carbon, you can do
different ratios, you can do impregnations. All sorts of different combinations,
and ultimately you just have to find that right lock and that right click, that right key,
and that's what we spent a tremendous amount of time doing here so that our clients don't have to.
We give that magic formulation, that magic recipe, we put it in this machine and out comes an amazing
result. So let's have a look at some of the results that we're seeing and showing to our
clients with these types of technologies. That's a room temperature extraction. Very, very green.
And we did this intentionally to really take a lot of that chlorophyll out of the cannabis,
but this was done with just aqueous ethanol and really you understand a lot of that chlorophyll
is coming over. You can some of the stuff is actually settled at the bottom there. But
really, really dark color. After using a one stage on one of the medias here, you can see the fallout
and the combination. It's starting to lighten up that color, and you can see kind of in the bottom
of this where that media has selectively bound to those constituents in there that are undesirable,
that are creating that dark color, and we've got a somewhat purified sample. And then when
we move to a second stage or a second formulation pass - that's what we have. And you've got your
cannabinoids and your terpenes still retained in there, but you have I mean you've got a water
clear extract - so that's fantastic. I really love you know the science behind this and and it goes
pretty deep and pretty wide. You know we're just talking about sort of organic medias when we talk
about some of the things that I mentioned, but it goes even deeper than that because you can have
synthetically or man-made medias. Things like ion anion exchange resins where we're actually
grabbing these molecules out of there through a charge that's just kind of - it's going to suck
it in. And this is where you can start purifying cannabinoids and purifying individual molecules.
Whether you're trying to remove something or you're trying to isolate something,
these are all things that can be done. So the important part is that you have a very robust,
very clean, very universal platform that's compliant - that you know is going to be
around for a long time. Obviously, you can see the the quality of construction with our units
is like everything else that we do - it's the best in the industry. So I really appreciate
you taking the time to watch the video. I think it was a great time well spent for everyone and
appreciate your support. Give us a call if you have any questions, we're here to help.
