Abstract A washing device for a centrifugal analyzer testing disk having a multiplicity of test cells each of which has a specimen and a reactant receiving hole communicating with the cell. The washing device has a washer body member with a multiplicity of fingers each receivable within the speciman receiving hole of each cell. Each finger has a bore communicating with a plenum within the body member. The body member communicates with tubing to a low pressure source such as a T-connector which can be connected to a faucet at one end to create a suction within the body member and draw cleaning solution through the reactant receiving hole of the test cell and out the specimen receiving hole when the disk is immersed in a cleaning solution.
The method of washing a centrifugal analyzer test disk having a multiplicity of radially extending test cells, each cell having a first and a second radially spaced aperature communicating with the cell interior, said method comprising: inserting into one of the first and second apertures of each cell a finger having a through bore so the bore is in flow communication with the respective cell, immersing said disk in a bath of washing solution so the solution may enter the other of said first and second apertures, and applying to the fingers a pressure lower than that of the bath to draw said solution through the cells with the fingers.
