Appl. No.:

7/588168

Inventors:

Julie F. Hoffman - Durham NC
Lionel D. Jones - Ventura CA

Assignee:

Akzo N.V. - Arnhem

International Classification:

B08B 900
B08B 902
B08B 906

US Classification:

134 2212

Abstract:

A cleaning apparatus for cleaning delivery probes used for dispensing protein-containing reagents. The apparatus includes: a bath of a cleaning solution for a protein-containing reagent; a device for lowering the probe into the cleaning solution for aspirating cleaning solution into the probe and for coating the outside of the probe; a device for raising the probe from the cleaning solution; a device for forcing primer liquid through the probe for expelling aspirated cleaning solution followed by primer liquid from the probe for washing the inside of the probe; and a device for deflecting cleaning solution and primer liquid expelled from the probe onto the outside of the probe for washing the outside of the probe.
