Anyone here ever use a borosilicate ,Pyrex, Friedrich condenser and have any comments on it? I'm a 100% novice and really like the looks of this thing. Am I barking up the wrong tree completely or on to better separation and efficiency? I'm pretty sure that I would want to incorporate some copper into this thing which looks quite possible, and digital thermometer placement seems like it should be easy enough when combined with a collection tube through a rubber bung in the collection outlet.
Anyone know of any better lab glass condensers for ethanol production?
If you don't know what I'm talking about then your advice is probably of limited use but welcome anyway and you can easily find out about them by doing a Google search of 'Friedrich condenser'.
Thanks,
Allen

Allen,
I used one in college, I will say that the output is very minimal when you consider that at most you will introduce a 20% wash for collection to a vessel of 300ml in size. They work great for the lab, I never considered using one for my experimentation of the spirits.
I imgine they make larger units, but are also very expensive to boot.

Thanks Brian.
Most of the ones that I can currently find cheap are 300ml. I've seen up to 600ml but only at full price which is nearly $200.00 USD. I can find the 300ml new pretty easy for around $20.00 on eBay and I also live near several large universities.
I know nothing about the output of these things however. I'm not looking to make a large unit with one but a compact stove top unit instead. Purity of a single run is more important to me than speed to a point. Purity looks easy to obtain with one of these but I have know idea what amount of output to expect in a given amount of time.
If it would be way too slow then I won't be interested.
You or anyone here know of the approx ml/hour output of one of these?
Thanks,
Allen

Uh, Allen, why would you want to mess with something so small? As Ati2ude sez, even at 20%, your wash could only yield 20% of 300ml, 60ml under optimum conditions, and you will will never be able to do even that much by distilling! Sheesh, that's hardly enough to even taste a sample, and what about making cuts? Yuck! Read this and the home distillation web site forums to get some ideas for a more practical approarch.

Oops. I did say the size was 300ml. I meant 300MM in length.

I realize now from another forum the my intended use of this thing may be a bit different than what one may think from no more details than I originally posted. So for the sake of clarity here are a few more details. Perhaps I'm looking at this device bass ackwards. My thinking was to pack the open area with copper mesh or chips held in by mesh plugs. Hooking up water lines with a valve control for flow rate of ice water. Plugging the top side opening with a rubber stopper fitted with a thermometer and line to a final condenser. Fitting the bottom vertical opening to the lid of a stock pot or similar and allowing the vapor to enter the condenser from the bottom and hopefully reflux before passing on to a final condenser through the rubber stopper at the top. Maybe that will clarify my intentions a bit though futile they may very well be for all I know. Here is a good example of the exact style that I'm thinking of. It's a coil type instead of a bulb type. http://cgi.ebay.com/Reflux-condenser-Friedrich-style-24-40-new_W0QQitemZ75864400 06QQcategoryZ26405QQrdZ1QQcmdZViewItem It may or may not work for all I know at this point but I must admit that I am intrigued by the glass factor. I like watching things work and the compactness would be nice.

OK Allen, now ya got my attention! At first I didn't really comprehend your question, but now that I have seen it, I think it makes perfect sense and I love the idea! I have no personal experience with this type device, but I am impressed with the potential for its use as a condenser/seperator. Of course, I imagine one must excercise a little more care when handling glass, but I can also appreciate the confidence one would have when looking at sparkling clean glass! Sorta gives one a good feeling being able to see inside your exchanger, huh?
Actually, I don't see any reason that this would not work very well and the prices aren't all that bad either. However, I am admidtitly ignorant when it comes to glass, so hopefully someone with greater knowledge can offer you more than just well wishes. In any case, please keep us posted on your success, or dissappointments, should you have any.
Best to you Allen, I think you just may have something here.

Glad to see that it caught your interest Spiritmaker. That's mostly where the fun is anyway. Playing with ideas. Using these condensers for our normal purpose probably isn't productive enough I'm guessing by now. A glass still sure is pretty though. I put this one together in my mind for about 250.00 USD for new, of the shelf, in stock items. Including the stand and clamps to hold it together. http://home.earthlink.net/~allensfilesubmit/sitebuildercontent/sitebuilderpictur es/project4.jpg B and F should have individual control of cooling flow. It may not produce a lot but it seems to me that it would produce the highest possible purity? I don't foresee it as an efficient production apparatus but perhaps a great experimental model. For $250 or maybe even less, I might just be willing to buy the parts and play with it. Gotta have yer toys. Allen
