You mean like rodinal or hc-110? What about fixer?
Fixers are also available as both power (mix it into water yourself) and liquid (dilute at time of use), and the liquids are a bit easier to use. Also, the liquids are generally rapid fixers.
Also, what's the difference between regular fixer and rapid fixer?
The short answer is that rapid fixers work faster.
The long answer is that rapid fixers are generally made from ammonium thiosulfate, whereas regular fixers are made from sodium thiosulfate. The ammonium form fixes more rapidly than the sodium form, but they both do the job (assuming they're used properly). Odors and the potential for nasal irritation differ from one type to the other, depending on ammonium vs. sodium, pH, and probably other factors. If you find one type objectionable in this respect, try another. If you tend to be sensitive to odors or are using a poorly ventilated area as your darkroom, you might want to look for an "odorless" fixer. They might not be
completely odorless, but they should be better than at least some others.
Is something like
this a good idea for storing mixed developer and fixer?
I prefer glass for developer, and I generally use glass for other items just because I've got a bunch of glass containers on hand. For the most part, I re-use drink bottles -- Snapple, soda, etc. I bought some smaller sizes of Boston rounds, though; it's hard to find glass drink bottles in less than about 300ml capacity.
What about thermometer.
This one looks nice because the reading is right on the top. Is the kodak one worth the extra money?
I'm not an expert on thermometers, but I've heard that the dial types can become miscalibrated because the index can get twisted out of position.
Some thermometers are supposed to be more precise and/or accurate than others. You'll probably be OK with just about anything sold by a photo retailer for B&W processing, but if you intend to process color film, you might want one of the more precise ones, since color's a bit more finicky about temperature than B&W.
