I am a new amateur chemist. I do run a Youtube channel where I post videos on DIY chemistry projects, demonstrations and academic experiments.i hope
everyone will support me

I'm really sorry I am posting this third time. All the other post got glitched. I apologize for that. I think it's ok now j_sum1 - 6-11-2019 at 20:36
Good to have you here. Sorry about the snuffed account. This happens from time to time and I don't think anyone knows why. My account was wiped a
month after joining too.
Anyway, welcome. I look forward to having a few moments to check out your channel.
Also got some glassware for the new lab . It was cheap and I got all these for 6usd.
Do you think I should have some specific equipment other than these which are absolutely necessary?

Invest in a reliable magnetic stir hot plate if you haven't already, and treat it like your one true god from there on. One of these is the
cornerstone of any experiment with a good yield. I promise it's worth saving for and paying for early.vibbzlab - 8-11-2019 at 06:58
I have got the condenser. So maybe I should invest for a heating mantle?Ubya - 8-11-2019 at 08:29

You can use an oil or water bath, it is not 100% necessary to have a heating mantlevibbzlab - 8-11-2019 at 08:32
Oh ok let's see what I can do about it.
Thats about heating element.
I will need cabinets to store chemicals now. Since I have got a lot of chemicals, I need to arrange them properlyvibbzlab - 9-11-2019 at 08:34
Is there alternative to silica crucibles. I actually wanted to do a video on something and it needs a very high temperatureSchmiddy - 9-11-2019 at 14:45
I checked out the channel, subbed and will be watching some of those testing vids later
I would also suggest you get a hot plate,you can find cheap ones in the 500-1500w range,single or double element with infinite control and you can do
an amazing amount with them.
I have a 1000w single element and use it for all my distillations indoors at home, she's a workhorse and I picked it up for $15 at a thrift shop. I
use it for everything from ether on up to to Kerosene but mostly water and alcohol.
I can use my boiling flasks directly on the element,with a water bath,oil bath or sand bath.
for most liquid distillations you don't need magnetic stirring,mag stirrers are nice for dissolving powders into liquids and for more complicated
reactions like refluxing and distillations that involve powders or non soluble components that need constant stirring to react.
I suggest you get a cheap hot plate first and then concern yourself with a more expensive magnetic stirring heating mantle. HydrogenSulphate - 9-11-2019 at 15:36
Welcome, welcome! I, too, am a brand new SciMad member, although I have been lurking around for years. elementcollector1 - 9-11-2019 at 16:25

Typically, a stainless steel egg dish/small bowl is a godsend for anything needing a makeshift crucible - it's about $4 for a decent size one and
it'll get you past 1000 C without a sweat. Failing that, a soup can will work about three times for temperatures around the melting point of aluminum
(after the third, it's almost guaranteed to spring a leak). What's your specific use?
I found my hot plate (with magnetic stirrer) for cheap on LabX - it's good to keep an eye on them in case a good auction comes up.vibbzlab - 9-11-2019 at 17:24
I wanted to heat potassium nitrate with carbon to make potassium nitrite.SWIM - 9-11-2019 at 18:03
You can also use a used automotive oil filter cartridge as a steel crucible.
Just cut the outer shell free of the internals at the base with a hacksaw.
I've put a steel cover on one and piled hot hardwood coals over and around it for hours with no problems at red heat.
I'm sure a good stainless steel bowl like elementcolector1 recommended, would last longer though, and probably contaminate your sample less.
On a small scale a nickel crucible might be a good choice.
You'd need a lot more heat than a Bunsen burner for a bowl or oil filter cartridge I bet.
The most recent thread for making nitrites on here also has a method for reducing the nitrate with zinc in aqueous solution.
It sounds pretty simple, but the poster warned about getting the reaction conditions right to avoid over reduction.Texium - 9-11-2019 at 18:24

Well, now I know what I'm doing
next time I change my oil!vibbzlab - 9-11-2019 at 19:16
Thank you friends for supporting my works. And about the hot plate I don't know where to get one here. I am from India,I don't find any hotplate cheap

Welcome vibbzlab, have you tried ebay for a hotplate? I got my first two stirring hotplates from that site. If all else fails, every once in a while,
one comes up for sale here. vibbzlab - 10-11-2019 at 17:41
I have not tried that yet. I have a round bottom flask with me and some distillation apparatus will it get heated up on a hotplate
