Alternatives to Brown Plastic Jugs
"SofaKing" wrote
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. I can't think of any good reason why anybody would want or need to use gallon size anything for keeping darkroom chemicals. Just in case somebody else has thought of at least one good reason, I suggest the gallon jugs in which distilled water is packaged. For 79 cents I've a jug and one gallon of distilled water. Purely a technicality: Volumn goes up by a power of three while surface area by a power of two. In brief, the low surface area to volumn ratio of large containers favors longer chemical life. That is with all things being equall which is far from being the case. From Google enter, Tri Ess Sciences . They have a large selection of bottles, jugs, and jars. Also they have a variety of caps, including Polycone, and lids. Dan |

Couldn't I use rinsed out antifreeze jugs or windshield washer jugs? Do they have to be opaque? Thx. Years ago I wandered into a shop that catered to home brewers (make your own wine & beer). They sold a variety of sized brown glass bottles and a nice assortment of caps for really cheap $. You may have bottles like them - they have the glass fingerhole at the top of the neck. They ranged in size from 30 oz. up to 160 oz. Of course they were all used. With a little washing they've become my alternative to the damned expensive brown plastic jugs. Doug |

Any good homebrew place should be able to get new glassware. The other choice is to go to the supermarket and walk around. By the time you've walked up and down the aisles you might have found a bottle in the right size for very little money. Of course you need to dump out whats in it. Nick |

I usually get to the bottom before it gets seriously brown. I keep stock HCA in a four litre plastic jug which used to contain vinegar. I do the same with dilute photo-flo. Everything else goes in smaller bottles. One good idea is to make sure that developer and fixer are kept in very different looking bottles. Everything should have labels on it too, but just having recognisible bottles reduces the chance of error. Plastic pop bottles with plastic caps are good. Glass bottles with plastic caps are very good. Peter. -- |

Everything else goes in smaller bottles. I have found the best containers yet to keep Dektol fresh are the four litre mylar wine bags sold by wine making stores. Mix the chemical, put it in the bag, make sure as much air as possible is removed -easy to do. I have found a bag of dektol stock solution in the back of a closet that was over three years old. It still hadn't turned brown and it still gave very good results when diluted 1:1 Take the " _ " out of to reply |

Maybe not available at just any supermarket, but those fancy-schmancy beer bottles with the built-in stopper with wire clamp are pretty good, too. I remember they used to hold Grolsch. Drink the beer, then store your stuff in them. -- .... 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) |

I did that with bottles of imitation vanilla when it went on sale for $.75/bottle and I simply poured the vanilla into a soda bottle ;) Regards, John S.

Are they magic or something. 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. Those cones can be removed so you can rinse behind them. Just in case some chemicals got in and you swapped caps with something different. A jeweler's screwdriver will slide into the edge and you can pry them out. Bert |

Mixing HC110 and Storage Bottles

To get the working solution, I mix one entire bottle with the appropriate amount of water. \Mark, Mark, Nice to see a discussion of darkroom practice in the newsgroup. Now, on to the subject. 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 I use a syringe, draw the amount of HC110 I need, stick the end of the syringe in the water and pressure it out. Then I draw in some of the water, pressure it out to rince the inside of the syringe. A bit of stirring afterwards does the trick. Bert |

Couldn't I use rinsed out antifreeze jugs or windshield washer jugs? Do they have to be opaque? Thx. Air (specifically O2) is probably a bigger concern than light. And gallon is a large quantity. Even if you make developer in gallon units you are better off with smaller bottles -- quart or liter. If you fill them right to the top, the oxidization is minimized and your chemicals will last longer. Dark quart bottles are what things like Hydrogen Peroxide come in. Just about any pharmacy has empty brown bottles in that size they will sell you. Here's another trick... The dusters you can buy at any office supply store contain a heavier than air chemical that is pretty much inert to photochemicals. If you put a couple of puffs of that stuff in the bottle, it acts as a float and keeps the bad old air away from the good old chemicals. |
