    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.

    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.

  • @Dan-vq4pz

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

    Awesome video as always. I'm wondering though, why are the solutions foaming so much ?

      I think the heat decomposes the ammonium bicarbonate maybe. Small amounts of gas get caught pretty easily in the chunky solution

    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.

    Why are your hydroxides so foamy? I've never had TACS foam.
    I remember the first time I made tetraaminocopper. I loved it so much I spent a whole bottle of acetone precipitating it. Amazingly, it's remained stable for over a decade!

    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.

    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.

  • @yertnamreg

    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!

    @lordhill1108 Před 4 lety

    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.

  • @FullModernAlchemist

    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.

  • @Landogarner83
    @Landogarner83 Před 4 lety

    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 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.

    Hi. Ni(III) is very rare - I personaly made only NiO(OH) (which is mixed with NiO2) by oxidizing Ni(OH)2 by persulfate. Nickel, unlike cobalt, doesn't form easily complexes in III oxidation state. So you have all the time [Ni(NH3)6]2+ in the beaker, which decomposed in to nickel hydroxide.
    Copper hydroxide contamination in your tetraaminnecopper carbonate is due to loss of ammonia on the air. These ammonia complexes slowly lose their ammonia, which is replaced by water. They must be store under ammonia atmosphere in closed container (I have for years [Cu(NH3)4]SO4.H2O in the jar without loss of ammonia - I added two drops of 25% ammonia to the jar to make protective atmosphere).

    For the Nickel Hexam1ne complex I've gotten decent results by putting metal nickel into a concentrated NH3 solution. Over a few days the metal broke down in the naturally alkaline NH3 and created the complex at ambient temperature.

    @JoshStLouis314 Před 4 lety

    Pump likely needs more current, it's a fair sized motor and under stall-load probably draws a few amps. The power supply should ideally rated for over 5 amps to be on the safe side.
