| 20080223786 | Methods and devices using a shrinkable support for porous monolithic materials - Articles of manufacture and devices and methods of forming and using the same are provided, wherein the article comprises a porous inorganic substrate contained in or bounded by a support made from an inorganic material are provided, wherein said porous substrate and support are heated to a temperature effective to shrink the support onto the porous substrate such that liquid tight contact is formed between the porous substrate and the support. In a preferred aspect, the porous inorganic substrate has a porosity of at least 5%, and is a porous monolith formed using a sol-gel method. The articles thus formed provide a confined fluid flow through the porous substrate, providing superior performance in separations, catalysis, filtration, and the like. | 09-18-2008 |
| 20080277347 | SAMPLE PREPARATION DEVICE AND METHOD UTILIZING POLYAMIDE TUBE - Polyamide sample preparation tubes with a hollow polyamide tube and an extraction medium contained within the tube are utilized in the sample preparation devices. The sample preparation tubes are substantially inert and show little tendency to dissolve or leach contaminants into nonaqueous liquids. The polyamide tubes may be used in preparing samples for analytical procedures such as GC, GC/MS, LC or LC/MS. | 11-13-2008 |
| 20090269247 | FLUID COLLECTION DEVICE WITH EXPRESSER PLUG HOLDER - A fluid collection device has a collection vial with a reservoir chamber for receiving a fluid sample. An elongated expresser is disposed within the collection via, which includes a fluid permeable base enabling passage of fluid sample into the reservoir chamber. A fluid test card is supported by an expresser bottom flange within the collection vial and a plunger is provided for compression of a swab saturated with fluid specimen into the reservoir chamber. A cap is provided for engaging the collection vial in order to seal the compressor, fluid test card, compressed swab, and plunger within the collection vial. | 10-29-2009 |
