Diffusion pump 04A with high volume operation at UHVP rates. This 04A is the smaller of the two diff pumps we sell, satisfies requirementsfor 12 liter short path setups and under. Liquid cooled pump well-suited for use in chemical manufacturing, where large quantities of gas have to be pumped away as quickly as possible. With no moving parts, these pumps are rugged and extremely reliable. Stainless steel is used for the pump bodies in order to minimize outgassing of the pumps, eliminate corrosion and to ensure a long operating lifetime of the pump. In short, diffusion pumps provide deeper vacuum and lower temps resulting in higher efficiency and increased speed. Comes with $900 dollars in flanges, connectors and diff oil. Comes stock with KF25 flanges but can always be reduced to KF16.
