Why are liquid developers packaged in HDPE?

This is at least considered dangerous lab practice in Germany.
So be aware what you are doing and who in any case might get access to such a bottle. Being a commercial photographer higher demands on your safety practice will be put on you in case of an accident.

fully agree. no food or food containers in the darkroom is a 'zero-cost' health insurance. why take the risc? grand children are hard to come by. a Dektol soda could make you seriously unpopularin the family.I don't need that guilt trip.:munch:

no chemicals in food bottles or in what could be mistaken as food bottles is a common-sense safety precaution, and I recommend aswell as practice it in my darkroom. rvrrything else is short-sided and might be regreted.:confused:

Just it is a "beer" bottle it doesn't mean it can be mistaked ass beer. The same way that most people use water or coca-cola bottles.

There are labels, smell, colours and stored among others chemicals to indicate that what is in side is not to drink. Unless if I were storing food in darkroom and chemicals shelf and storing chemicals in the fridge and food shelf.

After all, my beers bottles without the beer label is very identical to the empt bottles I find in stores but they are not brown. So it doesn't make any difference after all.

And my cleaning product are much more attempt than my chemicals bottles, more clean, better smell and easier to find.

Its really amazing how much money can be spent on cameras, film, accessories, books, supplies, etc., and yet, when it comes to something that is really inexpensive (considering repeated use) such as proper storage containers for the chemicals, safety isn't worth a penny.

Not chosing a standard lab bottle is not necessarily a issue of saving money. At that lab I refered to above certain beverage bottles were chosen as their caps were more gas tight than those of the lab ones.
I assume member marciofs had something similar on his mind when chosing that beer bottle.

I have taken to using Nalgene HDPE bottles found at my local outdoor shop. They are thick, cloudy white plastic and with good lids and come in a variety of shapes and sizes. I just googled them and noticed that they are also sold as labware.

But PET bottles are cheaper and better.

I use lemonade or soda bottles which when filled with their original drink give a hiss when opened and the pressure released so are obviously air impermeable. I am no expert on the materials these are made of. I have a mix of Extol which is almost a year old stored in these bottles and still works OK. I also use glass bottles but always leave a bubble of air as a completely filled bottle can burst due to liquid expansion in hot weather. I label all bottles with laboratory stick-off labels which wash off in hot water.

Giving a hiss does not necassarily mean that a bottle is air impermeable.

To my knowledge plain PET bottles just because of their still existant gas permeability yield shorter longevity for carbondioxide containing drinks.
