Vacuum Distillation Apparatus For the distillation of sensitive compounds a vacuum distillation is often used. By using a vacuum the boiling temperature of the compound is reduced; thus you can distill at a lower temperature and your compound does not decompose. This unit has a capacity of 1000ml, and is made of borosilicate glass with a column-type water cooled condenser. The boiling flask is 100ml, receiving flask is 500ml. This apparatus uses 24/40 ground glass joints throughout.
Vacuum distillation is highly technical and we would recommend reading "The Organic Chem Lab Survival Manual" for anyone not familiar with this procedure.
Distillation Set - Save 5% A complete set-up, including the distillation apparatus described above, with a 24" support stand, 20" support rings, and 2 flask clamps.

Ceramic Top Hot Plate NEW! Designed for laboratory use, this is a variable heat control, ceramic top heater. The heat is generated from resistant coils recessed into the ceramic top. It also comes with a removable ceramic top plate especially designed for round bottom flasks. Features:
Effective temperatures are from ambient to 600° F
Hot plate measures 6 x 6"
The open area in the removable ceramic top plate measures 3.75" diameter
500 Watts
For round bottom glassware up to 1000ml
From our in-house testing, we have found this versatile hot plate to be a good low-price alternative for those who do not wish to invest in a $250 Heating Mantle. Using the round-bottom ceramic adaptor, we brought 500ml of water to a boil in 14 minutes for a simple distillation procedure. A 5" support ring was able to securely support this compact and efficient heater. AP05$49.95
