More like a Culture ship. I think there is one named Limiting Reagent or Limiting Reactant.

FYI if that motor stalls out for long (more than a couple dozen seconds at a time, or less I'd bet) it could burn out. Motors draw more current the slower they run and afaik cheap dc motors like that are really not designed to pull max current for long at all, it gets really hot. This might not be a problem at all if that power supply has a low max current draw. If that's the case then there's no harm in stalling.

@ExtractionsAndIre

I think the power supply has a low current draw yeah. Will replace it with a 2A one as advised by others, to prevent it stalling

3:35 The nickel nitrate's stir bar wiggling oddly amused me

I should spend more time on transition metal complexes, because I really like the colours. Nice video!

Used one of those pumps before to do vacuum filtering. They need to draw something silly like 3.5 amps at 12V in order to run properly without stalling.

I use a small 2 stage diaphragm pump similar to the one you have for anything that i dont going through my normal pump. They are nice because they are easy to open and clean.

Excellent video as always, looking forward to seeing the energetics!

loved that last shot of the carbonato ligand test with the HCl, the music was also paired really well

That purple is fantastic! I agree with you, tetraamine copper is so vividly purple in real life it looks unreal. Hopefully you can get that nickel to “come down” as expected... good luck

Loving the included source links within the video. Much appreciated.

No matter the problems or the solutions I like your vids man.

Use this pump for resin and silicone degassing. Works great with 20A power supply. Consumes up to 2.5A as a vacuum pump and up to 7A as a pump.

Always a good day when one of your videos appears in my feed mate.

12:40 I had one of those in the lab for a short while, but found the aspirator pump is way better. If you use a aspirator pump at home, you can collect the water for the garden or to flush the toilet or something, so nothing is wasted. EDIT: I just found out that it is called an aspirator pump, not a water stream pump

Of course! It was the yellow getting into your reaction again that gave you a green precipitant when you should have had blue crystals.

Beginners guide to qualitative chemistry: Add some volume of reagent 1 followed by a bit of reagent 2. You'll know when sufficient reagent 2 is added when it's enough. Exact concentrations aren't critical. This is the chemistry equivalent of pi=3=e I love this channel

HINT: If you put your conc. ammonia in the freezer beforehand, makes it a little nicer to work with pouring it out of the bottle because the vapour pressure at such low temperature is very small (you don't get that terrible out-gassing as you crack the lid open!)

in future, you should take pictures of crazy colors that don't "come through" on camera with a phone camera or DSLR if youve got one. colors tend to be easier to pick out in photos than in video, especially if you want to edit things. I do photo retouching, if you don't feel like it, I'd be totally down to work on some beautiful chemistry colors!

I have used that pump before its okay but I have had a lot more success with a product from Piab called vacuum ejectors they use compressed air to pull a vacuum the nice thing about that is you wouldn't have to worry about any thing flowing back in to the pump. Here is a link if you would like to check them out www.piab.com/en-US/products/vacuum-pumps/

side note - i came across your videos coz I've been playing with oxalato complexes recently, and experimenting with cobalt at the moment. good results so far with iron, copper, nickel and aluminium but cobalt is a bitch. Trying to get it into the 3+ state, but it keeps turning back into the 2+ and precipitating out as pink cobalt ii oxalate. Some cool green colours but not the blue I'm aiming for.

Hey about the small diaphragm pump, I have use those for vacuum filtration for a fair while the adapter you are using looks like a charger adapter, probably not the best choice if you could find a 12v 2A adapter say from old routers it would run continuously and wouldn't stall ebay is MIA because of Covid, but a PWM controller would make things even more controlled (10A ~$6aud) The diaphragm is made of silicon so are the valves so the thing is pretty resistant to most chemicals, in my case what finally killed one of mine was vacuuming toluene for long periods. it permeates through the silicon and dissolves the PVC parts behind. the body is glass reinforced nylon so I don't think it would like HCL and a Cr6 These pumps are also fairly tolerant of liquids, you can pump liquids or gas/liquid mix, just need to reduce power a bit One other tip, I had 2 of these so I could use them in parallel for doubling the flow or in series for increasing the pressure or vacuum (won't quite double the pressure, more like 1.5 times, still not bad at all considering)

I've been using one of those same vacuum pumps for over 2 years now. Works great and is perfect for keeping a decent vacuum going for long periods without the noise. Definitely make sure you have a solid 12V though. They will get hot and bog down otherwise. It's survived all manner of nasty crap being spewed through it. Super easy to open and clean out. the rubber flappers are really quite sturdy. And in a pinch you can even pump water with it. Doesn't pump a huge volume but does put out good pressure.

Copper dihydroxy tetra-amine complex is my favorite color/colour. I keep some I made in a jar with an LED under-light for display.

It’s a gorgeous color and the nitrate and perchlorate complexes are mighty useful too.

Hey Davy, I've used these pumps before in the past, they really need almost 2A at 12V to get down to a reasonable vacuum level. They don't stall once they reach their maximum vac level when supplied sufficient current

Before watching the video, I’m sure all your work rewarded you with high yields of end products that were very pure and behaved exactly as you wanted them to.

I always come for the music

The plug is a US 220v plug. You see them a lot on washers or dryers for laundry units here.

the plug adapter for the pump is the uk adapter fyi :) some really nice tm chemistry going on here!

i come back here more often than I should

The plug for your big pump looks like a U.S. 240v plug. Commonly used for appliances like stoves, refrigerators, washers, and dryers. It's also not uncommon to see it on tools with large motors on them like mills, lathes, and CNC machines.

Always make me smile

Those pumps tend to draw a fair bit of current once you put a heavy enough load on them. Pulling a strong vacuum to suck something through the filter does just that and I suspect your power supply simply isn't up for the task. As the vacuum builds so does the current, eventually the supply can't keep up and the voltage tumbles until the motor stalls out. You want something that can deliver at least 3, better 5 Amps at around 9-12 Volts. An old computer power supply would work well, or maybe a cordless drill battery or in a pinch even a car battery charger if it has a 6V setting.

Used those pumps often, I found the best power supply was a TATTOO 12v. You just have to cut off the foot peddle and twist the wires together. Then you have a variable pump that can pull a vac of 30" of Mercury or just a little vacuum if needed.

I've also used that type of pump, you don't want to let it stall for any time since it will slowly overheat. That AC adapter is awful, try finding an actual 12V supply at several amps so it never stalls. Anyway, the pumps are surprisingly powerful and can really develop some serious pressure, on the order of around one bar. Pretty decent for a small plastic pump. The ones I got were pulled from a blood pressure cuff machine, hence the need for high pressure and moderate flow rate.

I have been using this kind of pump for years. They are quite reliable with the right power supply. Got mine from ebay as well only they were much cheaper and came with a psu

I made a filter pump using something just like this. I used a mason jar and some tubes and hot glue to act as a trap for nasty stuff. I charge it with bicarbonate solution for acid gasses, ice water for volatiles, etc. Might be an idea for your little pump.

His Beakers are like the Bermuda Triangle for bug of all sort. Looks like he has to bug fix his beaker again XD

It's the same little pump they use for your portable tire inflator... Just plugged in the pull-side... It's a Reed valve on an oil free piston (please give it a drop of oil it helps immensely) They have their uses...

You can get an aquarium air pump for 5-10 bucks and hook a hose to the air intake for vacuum filtration. Your motor most likely needs 12v by the way so check the adapter you hooked to it and also look at the ebay listing it may list the max Amperage. If not get a cheap speed controller from Aliexpress for 3-4 bucks and then you can adjust the pumping speed.

Motors typically take quite a bit of current. Especially ones under as much load as you are putting that one under. The little phone charger power supply is definitely the problem. Once vacuum gets low enough, the charger is hitting it's current limit and shutting itself off so it doesn't explode and/or catch fire ;) Find something that has a rating for current on it. You probably want something around 1A or maybe a bit more. That charger probably does 100-500mA. Love the videos!

I think NurdRage mentioned a cool way to make an aspirator based pump for vacuum filtering a while back in his lab equipment series. Basically just an aspirator adapter and a high power water pump he got cheap online running in a loop.

Other labs use a water fountain into water tap vacuum adapter. Water cheap in PNW so mine just drains. Gets 12 mm vacuum with cold water. Plus is acids, ammonia, etc vapors goes to the drain or ice water tank.
