    Hi All,

    I was developing with the tetanal kit some films when my thermometer slipped my hands and I think contaminated the developer :/, right at the end of the dev process.
    It was a red colored liquid that would not stain anything but my latex gloves. I dont think it was any kind of mercury liquid.

    How save is it to reuse the developer? If working (after a test roll) would its live be diminished?

    Thanks!

    I'm pretty sure it is alcohol with red dye. Not sure how, or if, it will contaminate your chem though.

    Your images are much more valuable than the cost of chemicals. Buy new developer.

    Well the alcohol won't do anything, the dye might stain the film a tiny bit. Mercury is silver coloured. Blue or red liquids in thermometers are alcohol and dye, you can't dye mercury.

    Thanks I did. Still that leaves the question of alcohol being a developer killer, as other have mentioned! I would think it just makes the solution more dilute and it was only few drops anyway.

    Do a stringent clip test (an inch of film you expose in your camera) in the 'contaminated' developer. It might turn out that the contamination is not worthy of worry. - David Lyga

    Ethanol can be used as cosolvent for phenidone, so it's unlikely that a small amount of an alcohol will affect a black & white developer. Just run a snip test to determine if there is any problem.

    I did run a test today and can state that the Tetenal Color Developer was not affected by the drop of alcohol from the colored thermometer!

    That's good to know. One of us sooner or later is likely to have the same accident.Thanks
