Hello Noel,
Hi
But if you are running a lab you can scratch mix E6, [and the raw chemicals are still available (although nearest supplier is Germany for me)].
You only need a micro balance costing about 40 Euro, and water...
of course you could mix it by yourself from scratch with raw chemicals if you want to. But that does not make sense for a professional lab, because using the professional E6 bulk lab kits from Fuji Hunt, Tetenal or Bellini is much, much easier and more cost effective for the professional labs.
I've seen some professional labs from inside, I know several lab owners very well. They just use the E6 chemistry from the named producers, the same way they use the C41 and RA-4 chemistry from these producers. No differences, no problems. Period.
No one in this standard lab business mix the E6, C41 or RA-4 chemicals from scratch with raw chemicals.
A different situation is BW reversal development:
There I know four professional labs making (at least parts) of their chemistry from scratch with raw chemicals. But that is because they have designed their own, special process.
It is hard home processing E6 but I've done it in past...
Noel
E6 home processing is easy, especially if you are using
- the home developing kits from Fuji, Tetenal or Bellini
- a Jobo processing machine.
Best regards,
Henning
