    At this point, my lab is in several places: the garden out front, the whole of the dining rooms (indoor greenhouse, brewing station, chemistry tables), kitchen (various experiments), reading room, broom closet with a heater to keep it around 40 degrees C for incubation experiments. I have more glass jars than I care to say, and nearly every corner of my place is littered with some sort of experiment in progress.

    I see the lab as the externalization of the self - and the different lab types reflect on the different belief systems people have. I don't think there is any merit in one type of setup versus another - all that matters is that the mirror that reflects the internal to the external, and vice-versa, is kept clean.

    A big part of my lab is the stove - currently running an essential oil distillation of cedar.

    I've known temp controllers to be fairly tiny (6cm x 3cm x 8cm) but the ones you have are fairly large. Are they special types of controllers?

    For the condenser coolant tank, what coolant do you use?

    What does a condenser dryer do? I've never heard of such a thing so am more than curious.
    I built these controllers about 12 years ago, with large high amp
    realays in them. I also use the new small controllers with the
    s/s realays, they are fantastic.

    The old controllers cost me around $500 each just for parts, the
    new ones are $10 to $20 depending on temp or amp level.

    Drying tubes are often used with condensers to allow for expansion and
    contraction of the gases and to prevent moisture from entering the
    sysem. These are vey helpful if you are working with spirits that are
    hygroscopic as in ethanol, etc.

    Instead of the drying tubes I use 3 connected bottles with concentrated
    sulphuric acid as a desiccant.

    This condenser coolant is just water with a few drops of bleach, but I
    have used methylated spirits, acetone, dry ice, for different types of
    condensing.

    I agree the new ones are awesome and cheap.

    Dumb question - how do you prevent sulphuric acid fumes from entering the system?

    At first I thought that the pics of A, B and C looked like a compressor/chiller and then I was wondering if you were using freon or something similar (R410A) but now I get it.

    Thanks again.
