Hello "die-seidenraupe",
First of all: ask your questions here and read the answers here. Otherwise, a forum like this quickly becomes pointless, as others want to know things too.
Next:
You can find chemicals, for example, at your local chemist’s (you may need to tell the chemist what you need them for). Or from
Omikron-Online,
Genec,
Th. Geyer and – best of all for photochemistry – Suvatlar in Hamburg. They don’t have a website, so you’ll have to contact them by post or phone. The address is: Fototechnik
Suvatlar, Stangestr. 11, 22765 Hamburg. You’ll have to look up the phone number yourself; I don’t have it to hand at the moment.
Generally speaking: most suppliers are a bit fussy about selling to private individuals. This is down to legislation designed primarily to protect consumers. For every other chemical in a photo lab, you’ll need a certificate of competence from a ‘proper’ chemical supplier; otherwise, you won’t get anything. For some substances, you’ll also need to provide a declaration of end use.
So, the easiest option is to order from Genec or Suvatlar, or try to persuade a chemist.
Best regards,
Franz
