Clark dclark@clarion.edu 1 Department of Chemistry, Mathematics, and Physics, Clarion University of Pennsylvania, Clarion, USA A convenient and inexpensive method for insulating fractional distillation columns in undergraduate laboratories with pre-slit, tubular pipe insulation that is widely available in hardware stores is described. This insulation can be quickly employed, can provide uniform insulation, and can be reused, which reduces the amount of trash generated from commonly used insulation. http://pubs.sciepub.com/wjce/4/3/1/wjce-4-3-1.pdf laboratories and demonstrations organic chemistry separations laboratory equipment experiment fractional distillation
