Abstract
Abstract A wash station for washing probes which are used with robotic systems. In particular, the wash station is used with robotic systems to provide simultaneous cleaning of both the interior and the exterior of multiple probes employed by the system. The wash station consists of a base, multiple chambers and multiple cylinders. The robotic probe to be cleaned is inserted within one of the cylinders where it is immersed in wash liquid to wash the exterior walls. The cylinders are separated by chambers. The wash liquid is removed from the wash station via a drain located in the base. In a preferred embodiment, independent access for each probe into the wash station is provided. In addition, the wash station provides a large capacity for fluid handling and is constructed such that the station is water tight. In a particularly preferred embodiment, the wash station is constructed from chemically compatible materials which will not be affected by exposure to the materials needed for general chemical synthesis.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
113 words
A wash station for simultaneously washing multiple robotic system probes comprising: a plurality of cylinders, wherein each cylinder has an upper end and a lower end and is provided with an opening throughout the entire length of the cylinder sufficient to accommodate one probe and allow for liquid to flow within the cylinder to wash the probe; a plurality of chambers, wherein each of the chambers has an upper portion and a lower tip and is provided with an opening throughout the entire length of the chamber sufficient to accommodate at least one of the cylinders; and a base unit which is provided with an opening sufficient to accommodate the plurality of chambers.
Claim 2
Dependent Claim
113 words
A wash station for simultaneously washing multiple robotic system probes comprising: a plurality of cylinders, wherein each cylinder has an upper end and a lower end and is provided with an opening throughout the entire length of the cylinder sufficient to accommodate one probe and allow for liquid to flow within the cylinder to wash the probe; a plurality of chambers, wherein each of the chambers has an upper portion and a lower tip and is provided with an opening throughout the entire length of the chamber sufficient to accommodate at least one of the cylinders; and a base unit which is provided with an opening sufficient to accommodate the plurality of chambers.
Claim 3
Dependent Claim
43 words
