Greets Beez... after much reading on the attributes of the LWR and the HDR, and having a few LWR successes, SWIA's friend wonders about condensor length and/or diameter in relation to the efficiency of a LWR (or even a HDR). In SWIA's prior dream I heard she used a 45cm long inner-coiled reflux condensor (approx. 12cm in diameter) on a 36 hr LWR; came out w/ beautiful gear. Now all her friend can obtain are some short fat Allihns, go figure. So I guess the question really is... Does size matter? (please no one with an inferiority complex lash out at me lol)--diameter, size, length, all of the above... Though she knows the little Allihns will perform efficiently, is it viable to throw 2 condensors together lengthways? Hell, or just opt for buying a real lengthy sumbitch? Why or why not? SWIA's friend was told the longer AND wider the better, even for nanos or small reactions...
