US Patent:

55782019, Nov 26, 1996

Filed:

May 26, 1995

Appl. No.:

8/451353

Inventors:

Charles F. Collier - Wilmington DE
Brian A. Deane - Wilmington DE
William E. Feathers - Cochranville PA
Robert A. King - Hockessin DE
Alexander D. Kopatsis - Wilmington DE

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

B01D 1104

US Classification:

210142

Abstract:

A reusable apparatus for multiphase, multistage countercurrent liquid separation is presented. The apparatus is particular useful in progressive multistage separation of target microorganisms from background organisms and materials with precise transfer, air exclusion, homogeneous mixing, isolation from the ambient atmosphere, in the absence of valves and at ow cost. The structure has at least one chamber in which a piston-like sliding bottom is sealingly moved or braked and includes internal structure for mixing, preferably a magnetic-stainless steel ball which can be reciprocated from the outside to mix the liquid contents. Motion of the bottom is limited by stops. A number of ways to actuate the apparatus are taught.

US Patent:

51302543, Jul 14, 1992

Filed:

May 25, 1990

Appl. No.:

7/528357

Inventors:

Charles F. Collier - Wilmington DE
James L. Seago - Wilmington DE
William G. DiMaio - Brookhaven PA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 110
B01L 302

US Classification:

436 54

Abstract:

A probe is introduced through the elastomeric cap of a closed sample container and moved sideways to stretch the cap and thereby provide an air passage to atmosphere while the sample is aspirated.

US Patent:

54338379, Jul 18, 1995

Filed:

Aug 27, 1993

Appl. No.:

8/113480

Inventors:

Donald H. Brunk - Wilmington DE
Charles F. Collier - Wilmington DE
Charles W. Robertson - Rockland DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 2726
G01N 27447

US Classification:

204299R

Abstract:

A gel cassette useful in electrophoretic separation of molecular fragments is disclosed, in which a gelatinous substrate is uniquely configured to concentrate similar separated fragments. Containment means is also disclosed which provides for the desired configuration of the substrate. The containment means further includes a cover design which locks into an open position to eliminate cross contamination. In addition, processes for the preparation of such cassettes and for use of the cassettes in separation and transfer apparatus are disclosed.

US Patent:

Filed:

Aug 27, 1993

Appl. No.:

8/113538

Inventors:

Donald H. Brunk - Wilmington DE
Charles F. Collier - Wilmington DE
Charles W. Robertson - Rockland DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 2726
G01N 27447

US Classification:

204301

Abstract:

A bowed framed membrane is disclosed for use in automated direct blot electrophoresis and subsequent membrane process steps to develop a chemiluminescent image of the resultant blot of selected fragments and to detect that image. A frame made from a thin rigid plastic plate such as polyethylene is provided with a window. A membrane covers that window and is bonded on two opposing sides only while the frame is held in a bowed condition. The membrane is maintained under tension during processing by the bowing permitting processing at the elevated temperatures used in molecular biological procedures without loss of flatness. Processes for preparing such frames and various utilities are also disclosed.

Filed:

Sep 16, 1992

Appl. No.:

7/945553

Inventors:

Charles F. Collier - Wilmington DE
David J. Regester - West Grove PA
Charles W. Robertson - Rockland DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 2726
G01N 27447

US Classification:

2041828

Abstract:

A separation and direct blot transfer module useful in gel electrophoresis is disclosed in which a transfer membrane stabilized by a frame is moved substantially orthogonally relative to the plane of the separation gel while in minimal contact with the end of the gel toward which molecular fragments are driven electrophoretically. The frame moves at a controlled velocity in a selected direction away from a line of contact that generates a controlled tension in the membrane which is a function of the loading on the line of contact. The module is particularly amenable to automated processing. Apparatus for automated separation, transfer, membrane processing, detection and identification is disclosed in which the module of the invention is employed.
