>[E]very chem lab should have a good number of 150-250 mL glass beakers on hand.
>Some large size glass test tubes will come in handy, and those are relatively cheap.
>Depending on what type of reactions you want to do, you may find it good to have petri dishes handy, either glass or plastic (they'd be good for crystallization experiments, certainly).
>You should definitely have a few pipettes, either the cheap plastic 3 mL kind, or if you can afford it, nicer glass droppers (Pasteur pipettes are fun to use, albeit fragile and hard to clean).
>You will definitely need a graduated cylinder, maybe a few, in different sizes, glass or plastic (definitely glass if you're planning on working with any strong acids or bases, or using organic solvents).
>You will find a scale, accurate to at least a tenth of a gram, to be an invaluable tool.
>Some litmus or pH paper will be useful.
>Oh, and a thermometer, of course!
>If you want to dispense precise quantities of any liquid, a 25 mL burette will be your best friend, though it's certainly not necessary.
8.a) This one seems relatively straightforward. Finally!
>a volumetric flask, for making precise stock solutions.
>A few Erlenmeyer flasks, for mixing things.
>A volumetric pipette, for making equal aliquots.
>Oh, and if you just want your lab to be that much more mad sciencey, you could have a distillation flask and a few condensation tubes bubbling in the background. If you want to make a significant investment, you could get a magnetic stirring platform, maybe one with good heating powers. Also great for whisking up an egg, or keeping some batter moving while you make pancakes. Pricey, though.
Thanks a ton for putting together that list!
EDIT: Formatting
What sort of filtration system did you use? Also, why no organic extraction? It looks like mitragynine and the other alkaloids are soluble in an organic solvent like chloroform or ethyl acetate--you can get ethyl acetate at low cost online. You'd just need a separation funnel to do it properly, and I think you could be getting crystalline extracts instead of this gritty stuff.
What did you use to raise the pH? Lye?
Not on topic, but you'd like this book.
Here's tubing on Amazon UK.
Stoppers. No holes, but you can buy a hole-cutter for stoppers (or make a jig to hold it and just drill a hole). You might be able to find some with holes if you look around some more.
Pyrex/borosilicate tube should be pretty easy to find as well. Usually you buy long pieces and cut and bend as needed.
Just in case there are US readers, I got these for this kind of old-school stuff:
I bought stoppers with holes and glass tube, and gum rubber tubing with no problem. That's thick-wall tube for use with vacuum, see the related products for cheaper thin-wall tubing.
Here is an Ebay link at $30/lb +$9 shipping. That's just from a google search, I'm sure you can find it cheaper.
Edit: Of course it's cheaper at Amazon

This is the one I used since I wanted a portable usb setup to hook up to a laptop battery pack. If you are not mobile, just get one of the pumps with wall plugs for more power.
