    Cheap Chemical Storage

    Was just wondering if the use of clean 1 and 2 liter soda pop bottles for the storage of mixed development solutions. I know that they are clear but if one kept them in a dark place at all times would they hold for reasonable time.
    If not, any other good ideas for an inexpensive source.

    They are perfect for what you are planning to use them for.

    That's what I use. It doesn't get much cheaper than that. Some rootbeer bottles are actually brown, too, but I use mostly water bottles because I don't drink pop.

    For developers, I favor glass. I use IBC root beer glass bottles for my working print developer, and various others (mostly in smaller sizes, since I mix my own in 1-liter or smaller quantities) for stock solutions. I've started using plastic for some non-developer storage. Mostly these are former flavored water and iced tea bottles; some of them have nice wide mouths.

    FWIW, Ryuji Suzuki wrote this piece on plastic bottles. As per that page, be sure to avoid #2 (HDPE) plastic bottles for developers, since HDPE is gas-permeable and developers are sensitive to this. HDPE is commonly used in milk, orange juice, and some water bottles. #1 (PET or PETE) bottles are better for developers. This type of plastic is used in soda, flavored water, and some plain water bottles.

    Oh, one other thing: I gather that the need to keep photochemicals dark is overblown. Most photochemicals won't be greatly damaged by exposure to light. I asked about this a while ago and got a list of photochemicals that shouldn't be exposed to light. It was a pretty obscure list, but I don't have it handy at the moment. I've stopped worrying about it.

    I found a unique and useful bottle the other day. In developing color RA4 and reversal RA4 in Cibachrome drums, 3 oz water washes are necessary at several steps. Rather than pouring water in to measuring cups for each of these steps, I fill a margarita mix bottle with water - using the built-in liquor pourer one can pour like a bartender and measure the quantity by count rather than visual measures. It works great for relatively non-critical steps like water rinses or stop baths when you need 3 or 4 ounces. I suppose one could do it for dev and blix also, but I prefer those to be more precise, altho the counts are pretty darned accurate.

    Just make sure they are well labelled and out of the reach of children

    In general, plastic is just fine. After all, that's what the manufacturers use to package developer concentrates.

    That said, it is probably prudent to consider how long you plan to store the chemicals when choosing how to store it. The plastic bottles that the manufacturers use are much thicker than ordinary soda bottles. There could be a difference in chemical composition of the plastcis as well - I haven't checked that.

    I generally use print developers as a one shot, so I don't worry about storage. I do store film developer (HC-110), and in that case I choose to use glass bottles. But the bottles I use are recycled beer or lemon juice concentrate bottles.

    Ain't no way I'm going to spend good money on bottles when I put a bin of them out for recycling every other week!

    I like the Ocean Spray Cranberry juice bottles, both the round 4 liter and the square 2 liter. My wife drinks this every day and I have an unlimited supply of sturdy jugs which can be discarded after a couple uses...EC

    When we go to our local brew pub we buy Growlers of our favorite beer from them and when its empty(which doesnt take too long) I wash them out and use them for chemicals. They are dark brown bottles that hold about a gallon of chemicals.
