How do you get the crystals out of the flask? I imagine they are stuck to the sides and need to be scraped off? If you have to use another solvent to get them out and then evap that, I guess I don't get the point of this. A flat baking dish works from my experience.
im pretty sure it was mixed well with the first solvent in a large amount , now you can introduce another solvent in small amount and use maybe a buchnel funnel and you will be left with the solid product.
Yes, you would add more solvent until you get to your desired concentration without pulling impurities. The crystal in this compound or sludge with an oil based compound are mostly impurities and your distillate would be your high concentration, though many people do a few baths to try and squeeze ever remaining amount of the given compound you're trying to extract, just depends if marginal returns is worth your time and using a flask this size would wager it wouldn't be though have at it. Many people also take the first run distillate and run a second time with more solvent to ensure any impurities there are also re-ran, so it's really how much you want to squeeze out and at what purity.
@@muntasirkamal1112 - I mean, why would you want that? It's full of impurities. At a certain point (typically one or two washes max) you reach a point of diminishing returns where the compound you're trying to separate from the other compounds/matter barely exists or is moot wasting time to get what is likely 5% remaining along with all of the other compounds/matter that has a higher flash point. For example, if I have 1Kg of mixed product, the flash point of some compounds in the mixture is below the compound I'm trying to get out means you distill and trash that first volume until you get near or to the flash point of your compound, you find the point (byway of test batches first) to find what's known as the heads where the lower temp compounds were vaporizing/distilling and still have residual of the previous compound mixed with your isolate, this temp is what you'd record as the start to your compound's isolated flash point, then with further testing and how pure you want it you toss the heads until you reach that purity and this is known as the hearts. You let the hearts portion or most pure portion of your isolate run until the next compounds in your mixture start to vaporize/condense and mix with your most pure product, this then is called the tails, and depending on what you're distilling you can add back a bit of the heads/tails or just keep the most pure isolated compound at the cost of trashing the first portion of the distilate and latter. Everything remaining in the flask is mostly without your compound at this point, though often people will wash it as I mentioned and reboot the distillation but you're only going to get a less pure and marginal additional volume. tl;dr: Point of all that was to illustrate you don't want the garbage left over in your flask. You just wash it out and dispose of it properly.
Guess if you really wanted that residual garbage for whatever reason than disposing of it using a solvent wash you could use a flexible flask brush long enough to reach but again, don't really know why you'd want it
can use an Aquadest to evaporated? I need answers of this.. cause Aquadest have in 100°C to evaporated.. what's Kind be better with in Instrument? Thank you🙏🏻
Hello. If you have any questions about rotary evaporator vacuum pump and short path distillation etc, please contact with me. And I am the manufacturer in China. All in all, any questions, just feel free to tell me. Thanks! My email: terry@lanphan.com Fb:Terry Lu
if you are in need of rotovap,please send us us an inquiry. kedayq.en.made-in-china.com/product/oyGQbItOEcVK/China-5L-Lab-Distiller-Vacuum-Rotovap-Rotavapor-Instrument-Rotary-Evaporator.html
A cheaper option that rotovap or rotary evaporation is a vacuum chamber. That said, most solvents will take quite a while to achieve full evap under normal atmospheric conditions and temps
oook so how come no rotavap vids actually show how to remove the dried sample from the flask?? without re-dissolving in solvent??? Can I scrap it off? It does not work. Pls help. I can't find a single video that actually shows this critical step.

Thank you so much man.
This was VERY ENLIGHTENING❤

@@j.ballsdeep420 this does not answer the question how the dried sample can be removed from the flask without adding any solvent.

Verrh informative video. Thank you. What is that vacuum pressure regulator or controller are you using?
I bet Travis is a hoot to work with. Thumbs up!

Cool, you are using the identical unit that I have. Thanks!

Please dear can you tell me how much the price for 5 litres .thanks
thanks, really helpful video
This is what happens when a well-meaning public speaking teacher says "make sure to use your hands!"
You should see me when I drive!
Thank you!
Hello, very nice video. I have 2 question:
1- Can use this with cannabis oil?
2- Which brand is the rotovap?
Thanks you.
Thanks! Of course!
Büchi Rotavapor R-114

How many decibels is that vacuum pump running at?
If you don't have a rotovap can you let the solvent disapate by leaving the jar open?
Often, yes!

It's so cool !!!!!!
How do I use this item to make colognes with herbs and carrier oils????
If you're asking that question you need to do more research 😂
I thought I followed your instructions precisely but now my dog is pregnant and my sister ran away from home!
You must have forgotten the splash-trap between the round bottom and the rotovap! Make sure you use vacuum grease on all your glass joints..
how long we can gate extract semi solid from plant with 100ml water?
I don't understand your question!
oook so how come no rotavap vids actually show how to remove the dried sample from the flask?? without re-dissolving in solvent??? Can I scrap it off? It does not work. Pls help. I can't find a single video that actually shows this critical step.
Usually you concentrate your extract and then pour it out to finish drying where it will be easy to collect.
Hey I might be a chef but this definitely looks like a DOPE machine to me... Can You Smoke It! ; )
At el celler de can roca we use them to make perfumes.

Thanks fam
Nice.

Is that mercury?
In the manometer, yes!

looks like the solvent disappeared
from receiving flask
Mmmmmm😊
