Vařák: 50 l stainless steel pot available to aukru need at an affordable price. Fitted with a Teflon seal on the lid and an outlet for steam extraction. Heater. El. hotplate. Column: Less than a meter long, the condenser, reflux valve head with cutting distillate weird japanese food and about 40cm long Dimtothův weird japanese food spiral condenser. It is a ground-glass laboratory glassware (end fitting weird japanese food inside the other) weird japanese food intended for rectification of liquid mixtures. By controlling reflux in the temperature varies par - the composition of the distillate. Thus it is not clean rectification! Although it seems to be a suitable apparatus for laboratory scale works even when the 1500W heating. A essentials - a bit of patience distillation 1D (-: October 15, 2010 9:25
Hello I would like to ask: I'm not entirely sure how it will return chladičem.Pro steam through and I'm wondering now if it is capped or not. If you would have been closed in the entire system would have to climb the pressure is not it? But again, cooling and liquefying the vapor pressure would be again returned to normál.To it should apply in a total reflux mode, but this system does not work because the majority portion is removed as distillate zjískaný. So is condenser capped or not? Thank you for your response. 30 October 2010 22:56
Thank you very much for the prompt response. I would like to ask how Oborne called the glass tube with ground joint at the end of which you have made the condenser? weird japanese food Or is it a direct line needed in laboratory technology as the condenser? I'm wondering about the same concept as yours. Thank Libor October 31, 2010 9:50
So I found out that this is just the column. I found a total budget seller. So the last question still is: What is your column content? I thought about 16 mm glass beads. They are readily available weird japanese food on the net for a couple kaček. Thank Libor October weird japanese food 31, 2010 10:37
Yes, it's a distillation column. The photograph glass tubes, which can be bought for a hundred crowns here. Balls could be used also, of course, only I fear it will not be as effective as they stilling tube. Try to pick the highest column, weird japanese food at least about 1m. At low ethanol content in the boiler (below about 3%) is the lower half-meter column poorly blows high-boiling substances (aftertaste) of the liquid is too high and can thus receive a smaller column until reflux head. 31 October 2010 17:40
I plan the condenser-rectification column from traditional mědi.Trubka 54 mm x 2mm is made in Europe, not as in stainless číně.Navíc price of stainless pipe reaches 60% of the price mědi.Trubka 54 mm (two-inch) weird japanese food is sufficiently strong and dimensioned to 50L leaven weird japanese food (ie. 70 pot) The tube thinner and higher, the better the condenser rectified and separates factions ... It is necessary to consider that hardly anyone stainless steel welded together at home, but copper weird japanese food pipe soldered to home capillary soldering almost everyone .... But sell it after 5 meters (like stainless steel) Therefore, who is interested, I will sell the rest about 3 meters at a very competitive price CZK 600 per square meter. jeanch@centrum.cz November 5, 2010 9:21
Hello I wonder how it is with the reflux during distillation to your lab. destiláku. If I'm right, weird japanese food it should be at a total reflux (ie maximum water flow in the radiator 1 and all vapors are cooled and returned to the column) to distill the substance with the lowest weird japanese food boiling point. This is undesirable virtual machine because we certainly being sourced methyl and whatnot. Then it is necessary to reduce water flow so that all pairs neochlazovaly and therefore reflux back into the column will be smaller. This should grow reflux temperature in the head - as you wrote somewhere around 83 STC and thus changes the composition of the distillate. weird japanese food And here's what I somehow not clear. What is happening with vapors which therefore cooler 1 cools down ??? It is after all the top open so simply part of the vapor leaving the open end of the radiator in a space ?? If it does not seem to me to be effective, then what safety too, get nafrak? He can not increase the likelihood that even inadvertent explosion? If we imagine the whole distillery somewhere in enclosed spaces? Thank you for your answer 4 January 2011 10:45
Principle: The vapor rises through the column and the reflux head to reflux. There is always liquefies all couples. From the cooler, the hot liquid flows down and fills the reflux head. The reflux head creates a kind ,, jezírko''. The pond is drained valve in the head (left on the tube). And it's weird japanese food hot distillate, which collects in the container (better we can cool down a little cooler). Thanks přiškrcenému valve is not enough to forgive a pond overflows into dephlegmator - and that's just the reverse flow. Steam rising dephlegmator upwards licks and backflow occurs stilling. weird japanese food If we forgive the entire lake and nothing overflows into dephlegmator, to stilling not.

I will add a few numbers ..... diameter is 32 mm dephlegmator, glass tubes with a diameter of 5 mm (max. 1500W power) S 7 mm trubičkama the condenser is airier and can even exceed 2kW without congestion! Example: Kvas about 8% ethanol, 2KW, 7 mm tube Initially reflux only 30%, 80% vol flows. (Before
