The LabSen® 221 pH electrode from Apera Instruments is specially designed for precise pH measurement in viscous solutions and solutions with low ion concentration. Manufactured using proprietary Swiss sensor technology, it ensures reliable performance in titrations and is compatible with TRIS buffer solutions.

Key Features:

• LabSen S-Type Hemispherical Glass Diaphragm: This low-resistance, rugged glass diaphragm ensures stable readings in 15 to 30 seconds. It is up to 10 times more durable than conventional products, reducing breakage risk during impacts.
• Movable Sleeve: The electrode features an easy-to-clean diaphragm sleeve that adjusts the infiltration rate of the electrolyte to match the ion concentration of the sample.
• Swiss Sensor Technology: Manufactured with high-quality materials, ensuring precision and longevity.
• TRIS Buffer Compatible: Ideal for use in environments requiring TRIS buffer solutions.
• Durable Reference System: Designed for longevity and reliability.
• BNC Connector Compatibility: The electrode is compatible with all pH meters that use BNC connectors, including Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PH800, PC800, PH820, and PC820.
• Temperature Compensation: For automatic temperature compensation, a separate temperature sensor (e.g., Apera Instruments MP500) is required, or the temperature can be manually input.

The LabSen® 221 pH electrode comes with a 6-month manufacturer’s warranty for peace of mind.
