[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have it as word of mouth from people at Bear Images in Palo Alto (a JOBO dealer) that the promised tablets will make up something like 125 ml. of solution. This may be fine for a drum processor, but I process two rolls at a time in a stainless steel tank, which wants 500 ml. Two points: 1) The keeping properties of the solutions in the Tetenal monopack C41 are quite good. Working solutions protected from oxidation by their gas spray (Protectan): minimum 6 weeks. The figures for the stabilizer and bleach-fix are longer. They don't commit with respect to partially used solutions--with fast film, the 500 ml can be used three times--but I have kept the stuff, partially used, for several weeks and have seen no problems with the processed negatives. 2) Tetenal makes a powder kit intended for traveling professionals. It does not include stabilizer, and, of course, has the disadvantage that one has to worry about dust from the powdered developer.

I contacted Jobo USA (US importer for Tetenal) and they told me to watch for the product to be brought to the US this summer. Summer has come and is almost gone and still no tablets. I am interested in them because they solve a common problem for low volume users, that being liquid chemistry going bad before you can use it! Read about them here: http://www.tetenal.com/daten/is017uk.htm (scroll down to COLORTEC C-41 PHOTOTABS) Has anyone had any experience with these products?
