This will be where stuff about chemistry goes. Feel free to edit as you like; I'm starting with lists of reagents and glassware that I will be bringing, and will add photos later today.
Glassware
All items are 24/40 standard taper unless otherwise specified. Some items are not glassware, but are used in reaction setups.
Prices are from Sigma-Aldrich's catalogue. In reality these can be had much more cheaply on ebay.
- Liebig condenser, 200mm ($55.10)
- Allihn condenser, 200mm ($172.40)
- 3-neck 500mL round-bottom flask ($94.20)
- 500mL round-bottom flask ($30.70)
- 250mL round-bottom flask ($27.00)
- 100mL round-bottom flask ($23.50)
- 50mL round-bottom flask ($22.90)
- 2x50mL round-bottom flask with distiller arm (not standard taper)
- Addition funnel, 125mL ($113.40)
- Separating funnel, 100mL (not standard taper; use a 1-hole stopper for an adapter) (~$20 from American Science and Surplus)
- Stillhead adapter ($68.10)
- Vacuum adapter ($47.10)
- Claisen adapter ($56.70)
- 0-360 degree thermometer
- 500mL beaker
- 250mL beaker
- 2x200mL beakers
- 40mL beaker
- 500mL one-arm Erlenmeyer flask (not standard taper)
- Buchner funnel
- 100mL graduated cylinder
- 10mL graduated cylinder
- 10mL burette
- Evaporating dish
- Aquarium pump with hoses (attaches to condenser for cooling it down) (~$25 at any aquarium store)
- Test tubes, various sizes, lots of them
Reagents
- 1 gallon methanol
- 1 gallon phosphoric acid
- 1 gallon hydrochloric acid, 12M
- ~1lb potassium hydroxide
- Calcium chloride, anhydrous (drying agent)
- Magnesium sulfate, anhydrous (drying agent)
Things that are broken but could be fixed
- A 500mL round-bottom longneck distillation flask with the distiller arm broken off. If someone has an acetylene torch, this could be repaired by fusing a glass tube onto it, or the hole could be sealed up and the flask used for a reflux reaction flask.
- A Liebig condenser, not standard taper, with part of the stillhead end in several pieces. Again, fixable with a hot enough torch.
- A vacuum aspirator with a bunch of pipe-fitting adapters. It works, but currently the adapters are on there really tight and I can't get them off. If someone has a plumber's wrench and a bench vise, this is easy to fix.
Workshops we could do
- Distillation and drying. 99% ethanol is really expensive, but we can make it cheaply with everclear (or cheap vodka) and a little bit of work.
- Liquid-liquid extraction and organic separation -- polar vs. non-polar solvents, how to use them
- Column chromatography
- Steam extraction from organic materials -- make your own essential oils and hydrosols
- Acid/base extraction
- Build a rotary evaporator
