Abstract
A system and method for valving on a sample processing device. The system can include a valve chamber, a process chamber, and a valve septum located between the valve chamber and the process chamber. The system can further include a fluid pathway in fluid communication with an inlet of the valve chamber, wherein the fluid pathway is configured to inhibit a liquid from entering the valve chamber and collecting adjacent the valve septum when the valve septum is in a closed configuration. The method can include rotating the sample processing device to exert a first force on the liquid that is insufficient to move the liquid into the valve chamber; forming an opening in the valve septum; and rotating the sample processing device to exert a second force on the liquid to move the liquid into the valve chamber.
