High Vacuum Distillation.

“…The device of the year in vacuum aids which, if not new is certainly not well enough known, is a valve for placing two mechanical vacuum pumps first in parallel and then in series as high vacuum is attained (8). Reviews are less in evidence (27); exceptions are two lengthy illustrated accounts (42, 44) of molecular distillation (38,40) in foreign jour-nals. Descriptions of advanced vacuum engineering (32) continue to be released by government agencies.…”
