Was it 'for your education', or for fun?

Nice, that's a great pic! Post your prep of the second compound when you get a chance.

My crowded little fumehood
Apparatus for making some ammonia soln. (NH4NO3 + KOH), improvised scrubbers in the background - some 30 years old milk bottles filled with water,
suck-back traps in between (probably unnecessary - I`ve also provided some aquarium anti suck-back valves - these work like a charm (but I don`t rely
on them if I were generating NO2 or something else more corrosive).

My fumehood was that clean right after I built it.
It would be very hard to get that way again (it would probably take a repainting).

Thanks aga.
It is rarely used (unfortunately !) and it is only about 1 year old. I work slow, prepare a lot before actually do any experiment (this setup, for
example, took couple of weeks to put together).
Not so much work on the "fiery side" of the hobby, also trying to avoid as much as possible visible / smelly fumes (very busy apartment neighborhood,
low profile is mandatory - afraid of "legal" interference).
And, yes, I am kind of obsessed with cleanliness (my wife too).

In regard to a request by aga in this thread, here are some pictures pertaining to what I have done this month so far.
I thought I would post them here since most of them are quite pretty and that way I don't have to double post them.
1: My Bromine distillation setup (it was very cold that day, hence no condenser)
2: My yield of Bromine
3: Cobalt(II) Chloride (almost anhydrous)
4: Cobalt(II) Nitrate Hexahydrate
5: Cobalt(II) Nitrate Hexahydrate after crystallization in a petri dish
6: Praseodymium(III) Nitrate (hydrated)
7: Sodium Ruthenate(VI)
8: Top layer = 2-Ethylhexanol, Bottom layer = Aqueous Sodium Phthalate

Mitotic skin cancer cells under my microscope at 1000x. You can clearly see the cells at different points in mitosis. The most incredible is a cell
near the middle of the picture in anaphase. The spindle fibers are clearly visible! The yellowish tint near the edge is due to my camera not being
perfectly in line with the microscope.

Cool! What stain is that? How is the sample prepared?

It was an H&E stain. That stain is really good for viewing cancer cells since the basic haemotoxylin used binds to acidic DNA/RNA. This makes the
extreme amounts of mitosis happening more visible and easier to identify.

You don't have skin cancer, do you?
Sasan and TAS, nice pictures! How's you make ethylhexanol? I'd like to!
