Eliminate pumps from cartridge-reader systems. Passive flow reduces hardware cost by 80%+ and enables truly portable field diagnostics.
The Problem
Traditional cartridge-reader systems rely on pumps, valves, and electronic controllers to move samples through diagnostic channels. These components dominate system cost, limit portability, require calibration, and introduce failure points.
Handheld field diagnostics require zero external hardware — a requirement that cannot be met with conventional pump-based architectures.
The Surnetics Solution
Surnetics gradient coatings self-propel patient samples through diagnostic channels without any pumps, valves, or power source. Multiple flow rates on a single device layer eliminate channel stacking.
Cartridge size shrinks dramatically. System BOM cost drops by 80% or more.
Competitive Advantages
Eliminating pumps, valves, and controllers removes the dominant cost driver in cartridge-based diagnostic systems.
No external power or hardware required for fluid management — enabling genuinely handheld field diagnostics.
Multiple independent flow rates on a single device layer eliminate complex channel stacking and reduce cartridge size.
Flow behavior is determined by the coating, not by mechanical components — eliminating pump calibration and drift.
