Diffusion pumps

AUG 01, 1972

Over the past ten or fifteen years, modifications of the diffusion pump have doubled its pumping speed reduced backstreaming of pump fluids by four or five orders of magnitude. These improvements result from redesign of some basic pump features and from development of new pump fluids with lower vapor pressures.
