Alternatives to Brown Plastic Jugs
My local photo place wants $9 a pop for those 1 gal. chemical jugs! I feel
it's a little much for 25 cents worth of plastic. Are they magic or something. Couldn't I use rinsed out antifreeze jugs or windshield washer jugs? Do they have to be opaque? Thx. |

Couldn't I use rinsed out antifreeze jugs or windshield washer jugs? Do they have to be opaque? Thx. A few thoughts: In my case, I have a permanent darkroom, the lights are on in there during setup, but when it is unused, or when I am working, it is dark in there - so dark bottles are probably not all that important since the room is dark almost all the time. Having said that - I use a lot of little bottles - for example - I use HC-110 as my main film developer - I dilute the syrup into the stock solution strength, then put it into 2oz bottles - brown glass, which I buy in bulk and they are not expensive (about $0.30 each?). To get the working solution, I mix one entire bottle with the appropriate amount of water. I do a similar thing with Kodak HCA, Dektol, etc, using 2oz, 4oz and 8oz bottles as is appropriate so that for each working session I use a small number of bottles and never use a partial bottle. Since the bottles are full, there is little air in them, and I suspect that the stock solutions might last longer - but I have no data on this. The main chemical that I do not use as one shot is fixer - this is because disposal of it in my case is a PITA, so I use it to exhaustion. For fixer, I use brown glass 1gal jugs. Don't remember what the 1 Gal jugs cost, but I don't think that they were as much as the plastic ones that you are looking at. If I recall correctly, the type of bottles that I use, which can be found at scientific supply houses are referred to as 'Boston Round' or something like that - I have found two different types of caps for these - ones with plastic cone shaped liners, and ones with cardboard liners - I prefer the plastic cone ones since they hold up better and probably retain fewer chemicals on them.

If you don't mind semi-transparent plastic, then 1-gallon bottles with caps can be had new for between $1 to $3 each. Check out http://www.usplastic.com. Try searching on "industrial jugs". Their delivery service is very fast. But what we could really use here is some true expert input from a plastics engineer. Plastic technology is a mystery. Some plastics let oxygen flow through, some let hydrocarbons pass, some are dark looking but are not really opaque to light. What's best for chemicals? In our lab we have some true light-opaque chemistry bottles that cost as much as $60 for a quart size. |

Mixing HC110 and Storage Bottles

Check out this link: http://www.covingtoninnovations.com/hc110/ This presents an alternative to making the first dilution of HC110 and avoids any aging of the stock solution. My darkroom instructor recommended it and I have found it very practical. I simply go directly from syrup to final dilution using 16.1 ml of HC110 in 485 ml of filtered water. I measure the syrup in a 50 ml glass graduated cylinder, so I am accurate to around plus/minus .15 ml. After measuring the syrup, I add around 10 ml of water, cap it with my thumb (wearing a protective glove) and shake it before putting it in the final bottle. I rinse several more times thru the cylinder so that I am sure to get residual syrup into the mix. I put mix my solution in a 500ml water bottle so there is little error and no real measurement of the water; just fill the bottle to a mark on the neck that equals 16.1 plus 485 ml of solution. Seems close enough since .15 ml is around 2%. Any error in measurement is likely less important than degradation of the developer activity. Use the solution once and discard. No issue of storing at all. Also, I have found that the simple 1 liter pop bottles are perfect for my 8x10 trays. Everything is stored in a cabinet in a room that is normally dark anyhow. So light exposure is at the absolute minimum. Regards, PSsquare |

My local photo place wants $9 a pop for those 1 gal. chemical jugs! Cute, isn't it? Check out the price of an empty spray bottle at the hardware store - $3.00 - compared to the same bottle filled with Windex - $1.50. Chemical jugs are made from thicker PE plastic than milk-jugs. I have found the best equivalent to be Minute-Maid Orange Juice jugs at $5.00 each when filled with rather good orange juice. As other's have mentioned, 1 liter/quart PETE soda bottles are also suitable as PETE is reasonably gas impermeable. And splitting a gallon of solution into smaller lots makes it last a lot longer. My favorite, though, is the Cubitaner: http://bestcontainers.com/hedpak---c...packaging.html Dektol stock keeps for a year (when made with boiled distilled water; stirred, not shaken). Do-it-yourself cubitainers can be made from the cartons and aluminized Mylar bags from wine-in-a-box (don't even think of drinking the wine, it's uniformly awful). -- Nicholas O.

Some plastics let oxygen flow through, some let hydrocarbons pass, some are dark looking but are not really opaque to light. What's best for chemicals? Perhaps you missed my post on this very question in another thread ("Rodinal"). Here's the gist of it: From his page on plastic bottles ["he" being someone named "Ryuji"] (http://silvergrain.org/Photo-Tech/plastic.html): Why manufacturers and chemists recommend glass bottles for storing photographic chemicals has a lot to do with idiot-proof factors. With a little attention, inexpensive and convenient plastic bottles can be used for most photographic chemical storage without compromising their shelf life. Plastic materials and chemical properties material gas permeability acid resistance max usable temp --------------------------------------------------------------- PET (PETE) very good reasonable 60°C HDPE poor good 120°C PVC very good reasonable 70°C LDPE very poor good 80°C PVdc (Saran wrap) excellent reasonable 65°C PET (polyethylene terephthalate) is used as a clear (colorless or tinted) bottle material in bottled water products. It has very small permeability to oxygen and nitrogen. Use PET for developers. Use PET or HDPE for most other chemicals. If you store acetic acid stop bath in concentrated form, use HDPE. If PVC coated cap is available, use it by all means. My bottles of D-76, Microphen, and various other experimental formula are still alive and as vigorous in filled and tightly capped 500ml PET bottles after two years! And as someone else pointed out, the best is still glass (assuming a good tight seal of some non-permeable material). -- .... but never have I encountered a guy who could not be bothered to make his own case on his own show. - Eric Alterman on his appearance on Dennis Miller's bomb of a show on CNBC (3/17/04) |
