Hahahaha naw dude just a mg scale, some measuring cups and measuring spoons, some DI water, and an empty bottle of sufficient size to hold the solution.
The DI water you can get from any pharmacy/drug store.
The beauty about using a low concentration like 1mg/mL your doses end up being accurate even without not too accurate of equipe
I wouldn't use measuring spoons just because it's so easy to get oral syringes and they're much more accurate and easier to use (ie, no spillage over the top of a spoon, etc). You can get a nice oral syringe at a pharmacy for a dollar or two, or you can ask them for some for free.
Also (not directed at you but the OP), you need to just measure the liquid beforehand and then throw the chemical in it. I usually use vodka or something as the entire liquid but at least use half vodka or something (or any alcohol). The alcohol will prevent bacterial growth over the long term. Definitely use distilled water too. I usually just make a liquid measurement solution out of a portion of my dry chemical at a time just because stored dry it's even more stable, but whatever you prefer.
So if you weigh out 100mg of 2C-B (or whatever), then get a jar or vial and put 100mL of liquid in. Then toss in the 100mg and stir until it's completely dissolved. Most chemicals (especially the 2C-Xs and most other phenethylamine salts) will dissolve up to 20 or 30mg/mL, or even more, so it should be any problem at all to get it all to dissolve. Once it's dissolved, it will be equally distributed throughout the liquid and you don't even need to stir before you dose or anything, it basically becomes part of the water, for all intents and purposes anyway. If you wanted to dose 20mg, you'd use your oral syringe to suck up 20mg and just squirt it into your mouth or into water or something and drink it.
Zero out the weight of the capsul and weigh it in a cap direct. I haven't noticed and real weight fluctuation between caps. It could help prevent loss from weight tray transfer. Also 2cb I recommend 8 if not 10 mg
If you don't have an expensive scale it's more accurate if you don't zero it out first and just do some math. I usually actually just do this to weigh stuff and it works well: Put the weighing tray on the scale, or if your scale has the tray built in, put a folded piece of card or something on it. It will read, say, 2680mg. Then if you want to weigh out 20mg, put the chemical on there until it reads 2700mg (2700-2680 = 20). It seems that the cheap scales are less accurate when they're reading a very low number than when they're reading a higher number. That's what I've noticed.
