I second the vote for Kugloror apparatus. It can be made from a couple of
ground glass joints (one inner, one outer), and a couple of pieces of
glass tubing using moderate glassblowing skills. Or, the glassware can be
purchase for not too much money from glassware vendors. The rotating
portion can be attached to a standard round bottom flask. I've used a sand
bath for heating and manual twirling during distillation (with 2 3-finger
clamps to hold the apparatus steady) for a really low tech solution.
