Abstract: The apparatus disclosed herein features a substrate arm and gripper, a platform having a top surface located opposite the substrate when the substrate arm is in a specimen processing position and featuring at least one fluid port located on a surface of the platform facing the substrate and at least one vacuum port located on the surface of the platform facing the substrate, and during operation, the apparatus is configured to (a) dispense a first quantity of fluid from the at least one fluid port to fill a separation between the substrate and the platform, (b) dispense an additional quantity of fluid from the at least one fluid port into the separation to displace a portion of the first quantity of fluid, and (c) remove the portion of the first quantity of fluid from the separation through the at least one vacuum port.

Abstract: An apparatus including a housing; a motor having a stator and a rotor, where the stator is connected to the housing; an environment barrier extending between the stator and the rotor; and a sealing system connecting the environment barrier with the housing. The sealing system includes a first seal interface and a second seal interface. The first seal interface connects to the housing at a first diameter which is at least partially less than or equal to an inner diameter of the stator. The second seal interface connects to the housing at a second diameter which is at least partially greater than or equal to an outer diameter of the stator.

Abstract: The systems and methods disclosed herein permit automated preparation of biological specimens for examination. The disclosed systems and methods provide fast, efficient, and highly uniform specimen processing using minimal quantities of fluids. The methods include at least a fixing phase for fixing a biological specimen to a substrate such as a microscope slide, a staining phase for staining the specimen, and a rinsing phase for rinsing the specimen. One or more of the fixing, staining, and rinsing phases include one or more agitation cycles for distributing reagents evenly and uniformly across the specimen. The systems can be implemented as a standalone device or as a component in a larger system for preparing and examining biological specimens.

Abstract: A substrate transport apparatus including a drive section and a first movable arm assembly. The drive section includes a first motor. The first motor includes a stator and a passive rotor. The first movable arm assembly is connected to the first motor. The substrate transport apparatus is configured for the first movable arm assembly to be positionable in a vacuum chamber with the passive rotor being in communication with an environment inside the vacuum chamber.

Abstract: An apparatus including a drive; a movable arm assembly; a plurality of sets of end effectors; and a controller. The end effectors are connected to the drive by the movable arm assembly. A first one of the sets of end effectors includes at least two of the end effectors, where the drive and the movable arm assembly are configured to move the at least two end effectors substantially in unison from a retracted position towards an extended position towards two different respective target locations. The at least two end effectors are at least partially independently movable relative to each other on the moveable arm assembly. The controller is configured to detect an offset of respective substrates on the at least two end effectors and adjust movement of the at least two end effectors relative to each other prior to placement of the substrates at the respective target locations.

Abstract: A substrate transport apparatus for a processing tool. The apparatus has a drive section, a movable arm, and an end effector. The arm is operably connected to the drive section. The end effector is connected to the movable arm for holding and transporting the substrate in the processing tool. The apparatus has a substrate inertial capture edge grip connected to the end effector and arranged so that the grip effects capture and centering of the substrate onto the end effector from substrate inertia.
