Green Bottles
 
I have found a bottle which says it holds 250mls and surprise, surprise this is very accurate( actually 254 mls to the very top). Many are not that accurate - usually the capacity is much greater so more protectan called for.So for those looking for a 250mls bottle such as is needed for a Jobo 35mm tank it is ideal. It's a Sainsburys lemon juice bottle should anyone like lemon juice and be seeking such a size of bottle once emptied.

Anyway I thought I'd ask some questions on green bottles.

Does green protect developers as well as brown which seems to be the standard recommended?

If not does fixer as opposed to developer need a brown bottle or is green or even clear OK for fixer?

Thanks

Mike

My thoughts. Stating the obvious, if the bottle is kept in a dark place such as a cupboard, then bottle colour doesn't matter much. ;)
It's only developer that suffers from excessive light as far as I know, but this could be as much due to the heating effect as degradation due to light. :confused:
Mine lives in a brown bottle, in the dark, under Tetenal Protectan spray.:)

True Dave. I suppose I was looking for what makes brown better if indeed it is than, say, green. I note that Winchester bottles sold for darkroom liquids are brown as indeed are Boots medicine bottles. Might just be a traditional colour as opposed to a better colour. Green is probably the new kid on the block compared to green.

Nothing new with coloured glass bottles, they have been around for hundreds of years, so I guess brown is traditional for medicine bottles and the like.

I keep my Dev in clear plastic 500ml PET Plastic Bottles.

My darkroom isn't dark - as it also doubles as the Utility Room too

So I asked the question on APUG about the effects of light on Developer

The Photographic Chemists on APUG said it was UV Radiation that did the damage to Developer.

UV is absorbed by regular window glass.

So unless you store your Developer outside in direct sunlight, somewhere sunny like Arizona, there is not much added protection in dark glass bottles.

I agree that UV is one component effecting Developer and that some UV is absorbed by glass, but not all, unless it is either very thick or special UV absorbing glass.
Certain of the so called alternative processes are dependent on UV for development, and they are developed behind glass.

Interesting contribution, Martin and thanks. Sounds as if on balance my fixer will certainly be OK in green glass and any developer also OK with a touch of Protectan and spending its time in a dark cupboard, only seeing the light of day for a few seconds on retrieving something from said cupboard.

Laphroaig is sold in green bottles and seems to keep quite well :D

True, Barry and produces pink elephants eventually. Thinking about it I am surprised that Firstcall haven't included it in its toning section.:D

Plenty of very nice wine in either green or brown bottles, and you get the pleasure of emptying the contents,Richard
