Filed:

May 11, 1987

Appl. No.:

7/048347

Inventors:

David H. Jeffs - Salt Lake City UT
Paul M. Jessop - Salt Lake City UT

Assignee:

Multi-Technology, Inc - Midvale UT

International Classification:

B29C 5700

US Classification:

264320

Abstract:

Low cost medical micro pipette tips for difficult to reach places, and related methods. The leading or distal portion of the micro pipette tips are materially elongated and ultra thin. This accommodates placement of the distal influent port, for receiving expensive biological extracts, in hard to reach places.

David H. Jeffs - Salt Lake City UT

Assignee:

Multi-Technology Inc. - Midvale UT

International Classification:

B65D 4500

US Classification:

210787

Abstract:

Fail safe releasible locks for capped centrifuge containers to insure closure integrity against specimen loss in whole or in part, the containers with cap being suitable for use in centrifuging and/or boiling liquid specimens and, if desired, for removal of processed specimens without removal of the lock and without opening of the cap.

Assignee:

Multi-Technology Inc. - Midvale UT

International Classification:

B65D 4500

US Classification:

220273

Abstract:

Fail safe externally-applied releasible locks and internally-disposed seals for capped centrifuge containers, cryogenic vials and the like to insure closure integrity against specimen loss in whole or in part and contamination, the containers with cap being suitable for use in centrifuging, boiling and freezing of liquid specimens and during shipping.

US Patent:

57114463, Jan 27, 1998

Filed:

Jan 16, 1996

Appl. No.:

8/585627

Inventors:

David H. Jeffs - Draper UT
Stephen Mackert - Sandy UT

Assignee:

Sorenson BioScience, Inc. - Salt Lake City UT

International Classification:

B65D 2102

US Classification:

220 2383

Abstract:

A cryogenic freezing vial. The vial includes a hollow sample container having exterior threads seated inside a hollow outer container having interior threads. The two containers define a surrounding volume there between which operates as a thermal barrier to resist temperature change within the sample container. A cap having a tubular wall extending outwardly from a continuous capping surface includes threads formed on both of the opposing sides of the tubular wall. The inner threaded side of the tubular wall can be screwed onto the hollow sample container, and then the outer threaded side of the tubular wall can be screwed into the hollow outer container. In such manner the cap is disposed in simultaneous threaded engagement between the two containers to intercouple and seal the containers from their surrounding environment.
