Sandstone is the developer and manufacturer of the Trak ® male fertility testing system, an FDA-cleared consumer
device that enables men to test their sperm count and semen volume at home. Trak helps lower the barriers to
fertility testing and management for couples trying to conceive. Trak employs CentriFluidic™ technology,
developed by scientists from Sandia National Laboratories. Sandstone’s portable CentriFluidic technology
combines fundamental centrifugal separation principles with mesofluidic design to unlock new capabilities in
healthcare and clinical diagnostics.

Sandstone is currently developing the Torq™ zero delay centrifuge system, a CentriFluidic device that provides
immediate blood plasma isolation and stabilization at the point of collection. The Torq system comprises a
compact, battery-powered centrifuge and uniquely designed discs that collect and spin blood samples immediately
following collection to hermetically isolate plasma from blood cells and other contaminants. The Torq system
provides superior sample purity and stability compared to existing blood collection technologies and is adaptable
to a wide range of diagnostic applications. Torq systems are currently deployed in investigational evaluations.
