US Patent:

59375361, Aug 17, 1999

Filed:

Oct 6, 1997

Appl. No.:

8/944860

Inventors:

Peter Kieselbach - Upper Black Eddy PA
Ilya Feygin - Mountainside NJ
Joseph J. Brzezinski - Bangor PA
Gregory L. Kirk - Skillman NJ
Thuc Nguyen - Bensalem PA
Joseph A. Mollica - Princeton NJ

Assignee:

Pharmacopeia, Inc. - Cranbury NJ

International Classification:

F26B 1330

US Classification:

34 92

Abstract:

A dryer for use with chemical compounds employs controlled vacuum, elevated temperature and dry, inert gas to dry the chemical compounds. The dryer includes a vacuum chamber into which trays containing the compounds are placed. The chamber includes heating elements which elevate the temperature of chemical samples placed within the chamber. Supplying and evacuating manifolds, each with a plurality of orifices for supplying and evacuating dry inert gas, provide a substantially laminar flow of dry inert gas just above the trays of chemical compounds which are to be dried. The laminar gas flow removes the unwanted vapor which tends to form above the tray of chemical compound, thus accelerating the drying process.
