Product Overview
With Silicone dioxide layer these AT-cut piezoelectric quartz crystals, vibrating at 10 MHz, are particularly suitable for liquid biosensing. The quartz crystal surface is flat and carefully polished. The gold electrode adhesion is enhanced by using a substrate of titanium.
Each sensor is preserved in a practical protective container, has single side electrode contacts and it is compatible with old openQCM and the new RF-spring contact system.
