QSense Pro

The QSense Pro is an 8-channel automated QCM-D system for high-throughput real-time molecular interaction analysis at surfaces and interfaces. It allows users to measure mass, thickness, and viscoelastic properties of rigid and soft films. The system includes an 8-channel configuration for high throughput and liquid handling for automated improved reproducibility and efficiency. With a minimum of 50 µl volume requirement in flow mode, it is intended for the use of small volumes of samples. It supports both flow and stagnant modes, providing flexibility with varying experimental conditions. The QSense Pro can be used in the areas of materials science, biotechnology, and surface chemistry research.
