Having m
ultiple stirring sticks and multiple thermometers is handy because you then don't need to keep cleaning things, but can still readily stir tall graduated cylinders to more quickly even out the temperature and get a more reliable reading. (And the general reminder that we all know and love: Thermometers are not stir sticks.)
As for measurement cups, how many, and how big, this is a bit of 'personal preference' thing, and depends on what specific processes and volumes you're doing. Are you doing small volume one shots,
I like a range of graduated cylinders ranging from 5mL syringe types up to 1L ones. Parts to be mixed together all get measured out in their own cylinder of suitable volume (don't use a 1L cylinder to measure out 10mL, use a 15-25mL instead), and then mixed together in a cylinder of suitable size for the target total as a sanity check. For example, I would measure out 750mL of liquid A in a 1L cylinder, then 250mL of B in something like a 250mL or 500mL cylinder. Once I've confirmed the volumes of A and B I can mix them into A's 1L cylinder. (Unless it is something that really can't be allowed to slop or dribble, then things get mixed into a container with more headroom. Another exception would be if I need to pour A INTO B, in which case B gets transferred to a larger vessel after it was measured out.)
As for how large of a container to store spent chemistry for later disposal: Depends on what it is you are storing, and the volume you're dealing with.
wow! thank you so much!You should check your local regulations for disposal of used solutions of photographic chemicals. In the UK they can be disposed of down the drain for small quantities as used in amateur home processing (not for a business, see weblink).
If you only intend to develop 2 rolls of 35mm at a time then that is approximately 600ml (2 x 290ml in a Paterson tank =580 but 600 is easier to calculate and gives a bit extra).
So you will need a small measuring cylinder to measure out the liquid chemicals and a larger measuring cylinder to make up to the required volume. Paterson make a 150ml measuring cylinder and a 600ml measuring cylinder. These would get you started.
You can just wash your stirrer and it is not necessary to have loads of them.
If you are going to re-use your stop and fix then you need containers to store them in. You should try to use a container that seals well and does not have an excessive air space (what I mean is the bottle should be full or nearly full). Old fizzy drink bottles, wine bottles etc can be used. Make sure you remove old labels and never store them where a child could accidentally drink from them thinking they are a soft drink. I use green gin bottles with screw caps or green wine bottles with "Vacuvin" stoppers. Label your bottles with what is in them and when you mixed them up. Then mark the labels for each film processed with them so that you do not exceed the capacity. I think from your other thread that you are going to use your developer one-shot so there is no need to store this.
A funnel is useful and also a plastic measuring jug. You can probably get a plastic measuring jug and funnel in the supermarket.
For very small quantities (e.g. wetting agent) a syringe is useful (5ml).
Get shooting some film and have fun!

I just run the film between my first and middle fingers (thoroughly washed, of course).Also the use of a squeegee is controversial and can scratch the film. It is best not to use one (IMHO).
I have a full set of mixing gear for each chemical, including measuring graduates, stirring rods, storage bottles, etc.As for measuring cups, I would say one for each chemical...
Agree.Remember, you must load the film loader in absolute darkness or in a changing bag.
Be careful with that 100 foot roll! Remember, you must load the film loader in absolute darkness or in a changing bag. You really don't want to ruin 100 feet of film.
Yes your Paterson changing bag will be fine. Make sure you put your arms in far enough to get a light seal. There are 2 elastic cuffs, an outer and an inner. I use my changing bag in a room with dim light. Also do up the zip and fold over the velcro flap. Take off your watch if it has luminous hands! Take off your watch anyway as it can catch on the elastic cuff.
By the way, what camera do you have?
I re-use the same measuring graduates with different chemicals, but that requires careful practice and lots of rinsing. If you have the space, its a good idea to have separate graduates for separate chemicals.

For something like that, if the 300 ml mark on the dollar store cups isn't accurate enough for what you need, than using the syringe won't add anything to that accuracy.I just use 1 litre measuring cups I got from the dollar store. If I ever needed something like 295 ml of water for example, I would fill the container to 300ml and use my syringe and take 5ml of water out of the cup.
