US Patent:

8216980, Jul 10, 2012

Filed:

Aug 8, 2005

Appl. No.:

11/198172

Inventors:

James P. Clarkin - Scottsdale AZ, US
Gary W. Nelson - Glendale AZ, US
Robert J. Macomber - Phoenix AZ, US

Assignee:

Polymicro Technologies LLC - Phoenix AZ

International Classification:

C40B 60/00

US Classification:

506 33

Abstract:

Micro channel array devices drawn from a bulk preform having an array of components to reduce the cross section. The reduced cross section fiber like structure is cut to produce individual arrays of small scale. End caps are drawn and optionally micro machined. The end caps are used to provide input and output ports and other structures for use with the micro channel arrays. A micro channel array may be used with different end caps for analysis and may form a lab on a chip or a component thereof.

Appl. No.:

10/086552

Inventors:

Robert Macomber - Phoenix AZ, US

Assignee:

Polymicro Technologies, LLC - Phoenix AZ

International Classification:

B01L009/00

US Classification:

422/104000, 422/099000, 422/100000, 436/180000

Abstract:

A device and method to dispense and manipulate multiple filaments includes at least three plates, each having at least one machined hole designed to accept one or more filaments. Based upon alignment of the machined holes in each of the at least three plates, the plates may be lowered over the top of one or more of the filaments. The position of the plates may be subsequently adjusted with respect to one another so as to secure the filaments in the device without having to individually secure the filaments into the device. Once secured, the filaments may be utilized in a predetermined application of an analytical instrument or dispensing device.

Appl. No.:

8/905845

Inventors:

Daniel Gene Jameson - Lincoln NE
Robert Joseph Macomber - Lincoln NE
Robert W. Allington - Lincoln NE

Assignee:

Isco, Inc. - Lincoln NE

International Classification:

B01D 1100

US Classification:

210634

Abstract:

To avoid deposits on the restrictor that channels extractant into a collector, a heated capillary tube pressure release restrictor, has a thermally insulated outlet end in a collecting trap substantially colder than the capillary tube. The restrictor is heated between the insulation and the capillary tube by Joulean heating. The solvent in the trap is at a pressure of 5 to 200 psi above atmospheric pressure. The thermal resistance of the insulation is selected to reduce the heat added to the extractant to a minimum and yet cause the temperature of the extractant to be in a range within which it is sufficiently hot so it does not freeze when added to the collection solvent but not so hot as to reduce partitioning of the extract and extractant before the extractant leaves the collection solvent. It has a thermal conductivity no greater than 60 BTU's per hour, per square foot, per inch for a one degree Fahrenheit difference.
