The XIA Model DP-03 differential pumps provide a cost effective means of providing a windowless, direct, line-of-sight transition between an ultra-high vacuum (UHV) region (< 1 x 10-9 Torr) and a high vacuum (HV) region (< 1 x 10-4 Torr). Differential pumps traditionally consist of a series of pumps separated from each other and from the UHV region by flow restricting throttles. The DP-03 adheres to this arrangement, consisting of a pair of throttles separated by an active pumping region, but with the addition of a patented design feature that creates active pumping of line-of-sight molecules. An adapter nipple on one end facilitates connection to HV, while an adapter cross on the other end makes the connection to the UHV system as well as providing ports for pressure monitoring, viewing, and attaching the user supplied secondary pump which completes the system.
