    Jobo noob needs assistance/advice with Duolab

    Greetings!

    Hope all is well.

    I recently got a Jobo Duolab which I am very excited about although it is outdated. I am a complete noob to the Jobo world and in need of some assistance. There is very, very little info on the web with some of the questions I have. I had to mail a few Jobo suppliers to get the manual, which, is not very informative either.

    Unfortunately, the Duolab did not come with chemical bottles and I would like to buy some. Which bottles can I buy to replace them? And are the chemical bottles universal or does the Duolab have specific bottles?

    However, it did come with 3 small developing tanks (can't remember the model names) - 2 with cogs and 1 with a manual developing lid.
    I would like to add an extension to it to develop more than 1 roll of film at a time. What should I get?

    In the manual, I noticed that the bottles need to be screwed into the developing tank during the developing stage. Is this a necessity or can on pour the chemicals in and put some sort of lid on to prevent the chemicals from pouring out.


    Your assistance would be greatly appreciated!!

    Thanks and have a great day/evening!

    I have never even heard of this machine. Contact Omer at Catlabs. He is the most knowledgeable person I know on Jobo and he may have bottles that will work.

    Thanks to everyone that has assisted me!!!

    I tested the Job over the weekend and it seems if the thermostat is not working so well.
    Turned the dial to 2, set the temp to 38. Filled the bath with 24 degree celsius water... 3 hours later, it sat on 27 degrees celsius.
    Will need to get it checked.

    Thanks!

    I'm new to this too (not even having done it yet...!) but from what I understand they are not designed to heat up the water, only to keep it at a regular temperature once warmed at the tap. It seems to me therefore that you just need to add almost hot tapwater (ie. slightly above the 38), and allow the Jobo to bring it down to a regular temperature before starting. I may be wrong, but this advice, which I've read elsewhere, sounds sensible to me.

    If it won't warm the water it is broken and needs some inspection. Start by checking the thermal reset switch then check all the circuit boards, connectors, switches and potentiometers for corrosion.

    These little babies heat up faster than any other Jobo. If it's slow to heat. Most likely an air bell in the heater line. . Use distilled water pouring it in the funnel marked 123. When the unit is empty pick it up and tilt it 90 degrees back and forth. Mine works great. The bottles are very hard to find, 300 ml. Any jobo bottle works, keeps liquids from running out during processing. I have a big Jobo CPP2, just a couple rolls I use the Duolab.
