The LabSen® 241-180 micro pH electrode from Apera Instruments is specifically designed for precise pH measurement in NMR tubes and other thin vessels. Manufactured with Swiss sensor technology, this electrode features a 180mm cylindrical micro glass membrane, low membrane resistance, and a long-life reference system for fast and stable measurements, even in high-temperature environments (up to 100°C).

Key Features:

• Swiss Sensor Technology – Advanced high-precision design for reliable pH measurements in small-volume samples.
• Cylindrical Micro Glass Membrane –
  • Length: 180mm
  • Diameter: 3mm
  • Low Membrane Resistance (<450MΩ) – Ensures fast response times and high measurement stability.
  • High-Temperature Compatibility – Usable in temperatures up to 100°C.
• Long-Life Reference System –
  • Consists of: Glass tube, AgCl, and reference silver wire.
  • Cotton-Filled Glass Tube – Prevents reaction between AgCl and electrolyte, ensuring stability across temperature changes and extending electrode lifespan.
• Small Volume Measurement – Ideal for NMR tubes and thin vessels, requiring a minimum sample volume of 50μl.

Compatibility:

• BNC Connector – Compatible with all Apera Instruments pH meters using BNC connectors, including:
  • PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PC800, PH820, and PC820.
• Temperature Compensation – Requires a separate temperature sensor (e.g., Apera Instruments MP500) for automatic temperature compensation or manual temperature input.

Warranty:

• 6-Month Manufacturer's Warranty ensuring long-term reliability for NMR tube pH measurements.
