Cypress Systems has served the research and teaching community with precision and quality electroanalytical instruments and electrodes since 1987. We offer high sensitivity, analog to micro-processor to computer controlled potentiostats at affordable prices. Our electroanalytical electrodes, Pt, Au, and glassy carbon at 3um to 3mm tip diameter, are encased in inert material and sealed to perfection. Each are tested and certified before shipment. Several reference electrodes are offered, including the 3mm tip diameter "no-leak" reference that is very stable and long-lived. Check our line of 3.5mm to 8mm tip diameter, shielded and polymer encased, pH electrodes-protected against breakage.
