Patent Images
1. A method of separating a sample of whole blood into serum and clot portions comprising the steps of:
- placing a quantity of whole blood into a container adapted to be centrifuged;
inserting into said container a supply of a thixotropic, water insoluble, substantially non-toxic sealant consisting essentially of a silicone fluid and an inert filler dispersed therein, said sealant having a specific gravity in the range of 1.026 to 1.092; and
centrifuging the blood into serum and clot portions until the sealant forms a separator between said portions.

Abstract
The separation of a sample of blood into serum and clot portions is accomplished by means of a sealant consisting essentially of a silicone fluid and silica dispersed therein. The separation is accomplished by inserting a device containing a supply of the sealant into a container holding a sample of the blood, the device being characterized by a nozzle portion which extends into the sample. The container and device are centrifuged so that it separates into serum and clot portions and the sealant, having a specific gravity of at least 1.026, separates the two portions.
