CPE-2 and Rinse

[gcap]

Hi all! I decided to enter into E-6 home development so I bought a used CPE-2 processor, tanks and other accessories. After reading posts here and the literature on the Jobo site I came up with the following setup: Tetenal 3 bath and Jobo 1530+1520 for the development of 6 120 or 3 220 films. Jobo literature states that with this combination minimum amount of liquid is 570ml. I was thinking of using the max amount for this processor which is 600ml to roundup measurements. Tetenal states that 500ml are enough for that number of films.

My concern, except the validity of the above statements, is that I have to use 6 X 600ml shots of rinse water after the First Developer and Color Developer which is a whooping 3.6 liters of water that must be kept in 38 degrees C on each step. How can I keep it at this temperature considering that the processor has no space for that large amount of liquid? How do you keep your rinse water in the recommended temperature?

Hello Gcap,

I don't prepare the water changes, but rinse the film with tap water at 38C. To control the temperature, I use a CLAGE water heater for that purpose:

Hallo Argus, thank you for your answer. If I understand correctly you could use heated water from the tap after some test. What your water heater provides? It doesn't have any temperature control.

Or just get yourself a plastic storage container (5+ gallon size) and fill it with 105 degree water if you don't have hot water where you are developing. According to the Kodak docs the wash temperature is not as critical as First Developer, it just has to be between 98-102F. So by the time you get to first wash it should be down to around 102, and by the time you get to final wash it should be 98 degrees or so.

If you had a tap-water temp. control unit you could have it set to your process temp. and get water straight from the tap. Also, the Jobo TBE-2 was designed to temper twelve one-liter bottles of chemistry. There is a recent thread on building a similar type tempering bath.

Could you point me to that thread please?

I calibrate the heater before each use. It has a small screw for adjusting termperature.
