This video shows how to set up a simple dstillation with the glassware I showed in the previous video.
Introduction to setting up your home laboratory
มุมมอง 70K10 ปีที่แล้ว
A video showing off some of the glassware you need to start your own home lab. This whole set cost me somewhere around $600, and so far, there hasn't been anything I've needed that hasn't been in this kit.
Lab coat? Sun glasses!? Jeez - thought I was bad! Also I’d recommend metal keck clips when clipping glass. Iv always just found grease tend to melt and contaminate my product. Don’t mean to shit all over your video or anything! Also haha plastic milk jugs and plastic jugs for storage is halarious…I like your collum it’s pretty darn large! Don’t store your acetone in your Maguiver plastic milk jugs! You are correct TBF, I go through a lot of acetone for cleaning but you didn’t mention to try washing up liquid and a set of pipe cleaners! Also you can get up to 5 neck flasks…hang on, is it me or do you have a 1l mantle and then a 2l flask? Or was that a 2l mantle with 2x 2l flasks. Also the flat bottom ‘flasks’ are called beakers. If you can manage to explain to me why people use volumetric flasks instead of graduated cylinders, I would HUGELY appreciate it. Also your reflux condensor is nice - is a longer version of what I have - I don’t use it for distillation though to be honest, I use a normal jacketed straight condenser for that. You have a nice set - what sort of chemistry are you doing bro?
Old Wuhan lab equipment 🤣🤣🤣🤣
Something I would view as indispensable is pipettes. Opt for ones with a three way valve bulb rather than a regular bulb, the cost difference is negligible. A 1ml is useful but they come in a range of sizes. 1ml is going to be the most reasonable one to get because you can always pipette from it multiple times until you get to the amount of ml you need, but larger volumes can definitely be taken from a volumetric flask or graduated cylinder. Graduated cylinders are also cheap and useful. Those would be my recommendations that I view as essential.
7:56 it's not flask, it's bakers but that's alright
Christ!!! Never use auto grease PERIOD! DONT LISTEN TO THIS FOOL! HE HAS NO CLUE!!!
WHAT?? I keep watching, and he keeps getting worse guessing what the glass is! This is a joke! Right! Ok ha ha 😂 🤣 I fell for it, this is a parody right guys??? Can't wait to see him go!
No! It's not a reflux , it's a snyder condenser column!
Okay! I'm pulling you're leg a bit, but bro, you have some learning to do , no disrespect! But you're wrong about all you have been saying so far! First, you can't use auto grease for joints! Because of temperature, caust8c chemicals, that will cause that grease to contaminate you're work, and a volumetric flask is not really what you want to 100% to measure out you're fluids ,, you want graduated cylinders! As the measurements are 100%, and uumm! Yeah, you need to get to know all of your glass! It's detrimental in chemistry! Some processes/ most chemical processes have ZERO ROOM for mistakes! Very easy to accidentally blow up a flask and get peppered with glass shrapnel! Or heaven forbid even easier and faster to cause an explosion do to usage of improper glassware! Just hang back , watch and observe, look up something if you're not sure about it! That's how you should get into this, sometimes it's not worth buying cheap glass kits, because they were such a good deal! Murphy's Law, if it seems to good to be true, it's because it usually is! I'm telling you this from trial and error, and a many years, of money I didn't have, frustration, sleepless nights, but!!!! I love chemistry, it's a true labor of love!
Holy shit! Where did you get that column from? Christ !
Are you 100 % sure you can use that automotive grease? Cause I just am not spending the small fortune for the stuff that's in those tiny ass tubes on Amazon ! I mean 40$ for a grease, seems wrong! If I can get the stuff you're showing at my local home depot or pep boys, for a 3rd the cost, please tell me you've researched this? I'd appreciate it ! Thanks
Jesse, we need to set up our home lab.
With a vacuum pump you could work up a low pressure distillation rig. That's pretty nice.
vacuum pump and vacuum filter (the distilling glass piece you showed can also pull a vacuum )
The stand was overpriced if it came on its own they are worth 20$
has expensive glassware but stores chemicals in old bottles lol. good video
3$ for 10 clips 😟 now its like 17$ for 10..
They have $20-30 multi meters with a thermometer up to 1000°C
I think you should take personal protection equipment far more seriously! I don't understand how you have done organic chemistry without using your claisen adapter. I couldn't do without a rotavap. For distilling and reflux I personally prefer the simpler claisen condenser. You will usually need a vacuum source and a vacuum gauge. You need more electro equipment if you're to do any kind of electrochemistry. Columns for chromatography and thin layer plates are very useful for separation and purification and analytical work monitoring reactions.. And to do chemistry without a fume-hood isn't usually a safe option. Remember that personal safety is the primary issue when doing almost anything, especially with dangerous chemicals!
Ah...wire...
Why do home chemistry? What is the point? What can be created?
@Edward Elizabeth Hitler learning for learning sake as no value.
Try American Science and Surplus in Chicago or Milwaukee
Where did you get the glassware and that heater?
Sabu sabu
How do you pump up water to a height of 1.3m with such a low power pump? I use a 550 L per hour pump and that just makes it!
Can I use glycerine instead of the grease?
Depends on the reaction/reactants. Sulphuric Acid is often best as it's high boiling point means it stays in the joints.
Chemistry's a fine hobby. Seen your distillation setup in next video. Curious to see how the water pump is worked from the coolant water. That would make a nice video
If your working with bromine use sulphuric acid instead of the greace
Dude where you at, you still doing chemistry at home?
This video was amazing
*go
Wait where did this guy g
sir, can you please give us some brief instructions on purchasing these items. can you provide detailed video or links, from where you bought all these items.
Amazon lol.
Why should someone trust what you say? You say not to skimp on the heating mantle, yet you skimp on safety glasses and gloves. You only have one kind of gloves, what if what you are working with reacts with the material your gloves are made of? Get more gloves, acquire proper eye protection, and please get a fire extinguisher.
Contact me for hard to get chemicals such as Acetic Anhydride and Iodine! zchemicals1988@gmail.com!
Very helpful video Thank you for making it
Contact me at zchemicals1988@gmail.com for any chemical needs you may have. I have many hard to gets!
Why don’t you use a column that highlights what you’re trying to discuss? Also. You’re getting the direction wrong.. you have the flow move upwards away from the rxn.
"Dont be cheep" "i use sun glasses"
Make more vids dude you've helped me plenty.
Hey what are some tips for me to start experimenting in chemistry?
Chemical Synthesis
Don't do what this guy did. Educate yourself on how to properly (that part is important) perform in a lab and how to use all the equipment, as well as storage of chemicals and safety.
Get real safety goggles.
too bad. The only brand of laboratory equipment here in our place is pyrex, they’re too expensive
Thanks to everyone for catching the minor slip up of beaker vs. flask. A few more minor(sarcasm) oopsies: The purpose of the claisen adapter, which he admits to not using, is not to mix two chemicals, but to prevent splashing and bumping during a vacuum distillation or any situation where bumping is expected. It's the perfect shape to prevent the still flask contents from contaminating the receiving flask contents. (smh) the hose barb on the final curved adapter he doesn't seem to know the name of. It's called a vacuum connector. I would argue that far and away the #1 purpose of it is to prevent a distillation from being a pressure bomb. Just leave it disconnected. Not just "nasty gasses" but pressure in all forms can escape through it with minimal loss to the desired distillate. Also, it's the perfect place to connect a vacuum source. The poster only mentions the likely 3rd most common use for the hose barb, and yes, that's a good use for it. But you don't juse let poisonous gasses escape through it. You connect a hose that either goes outside, or preferably into a scrubbing system.
What are your thoughts on the heating mantel in looking to get the 1000ml one but it’s got a couple reviews that say it only starts heating at 3/4 of the knob turned and I want to do some advanced reactions that require low heating
I know this is late but a hot water bath on a hotplate will do it, a mantle isn't necessary for low heating.
Wtf is that pool doing beside his bed!? Kinky 😅
It's for the water used in the condenser
what kind of kink involves a pool beside a bed lol
be careful kiddies! I'm not sure this guy is safe. but he cost a lot. you can do better on Ebay. please have the forethought not to leave your equipment where dogs, cats or dogs chasing cats or other people (little or big) to step on your mercury filled thermometer. I'm such a bitch.
MacGyver it! I like that👍 when I was 14 years old I got in trouble for making a flamethrower! The authorities ask me hey kid where did you learn this I said MacGyver! This was in 1987
Do you recommend a specific website that I can order glassware and chmicals from?
Have a look at deschem on eBay, everything you could ever need
@Tom Jones LOL I don't live in "the land of the free", I'm allowed to buy and posses Glass 😂
@Tom Jones UK - Its perfectly legal to possess glassware and most chemicals without a licence, there are a few that a licence is required for, such as deadly poisons and explosives precursors. Obviously Illegal drugs and (I think) its greater than 0.5 grams of explosives / black powder etc are a no no. For America to criminalise the possession of a chemistry set, yet you can walk into a supermarket and buy an Automatic assault rifle is ridiculous and just shows how backwards the Country is
@Tom Jones , can you post citation?
Great video. I need to get a heating mantle and reflux condensor. My "lab" mainly consists of mason jars and stir rods, so :) It's pretty sophisticated.
Expensive
