US Patent:

59605308, Oct 5, 1999

Filed:

Feb 27, 1997

Appl. No.:

8/807177

Inventors:

Alexander F. Kerr - Wappingers Falls NY
Nicholas F. DiDomenico - Pine Bush NY

Assignee:

Bayer Corporation - Tarrytown NY

International Classification:

B23P 1902

US Classification:

29525

Abstract:

The sample liquid aspirating and dispensing probe includes a tubular plastic inner member and a tubular metallic outer member. One or more sections of the plastic inner member are drawn-down in dies to provide a large diameter section, a small diameter section and an intermediate transition section. The plastic member is inserted in the metal member and annealed to conform the profile of the plastic member transition section with a streamlined transition section of the metal outer member. The dual member probe has an ultra-smooth interior surface, substantially free of eddy-forming imperfections. Thus there is minimal likelihood of turbulent eddies forming when rinse liquid is directed through the probe. The metallic member provides the probe with a conductive capability for capacitive liquid level sensing.
