The LabSen® 241-3 micro pH electrode from Apera Instruments is designed for precise pH measurement in small sample volumes (>30 μl) and thin test tubes. Engineered with Swiss sensor technology, this electrode features a special cylindrical micro-electrode tip and a long-life reference system, ensuring high stability, durability, and accuracy.

Key Features:

• Swiss Sensor Technology – High-precision design for reliable micro-volume pH measurements.
• Cylindrical Micro Glass Membrane –
  • Tip Diameter: 3mm
  • Steel Tube Diameter: 4mm
  • Temperature Compatibility: Up to 100°C
  • Stainless Steel Sheath – Protects against impact damage, ensuring durability.
• Long-Life Reference System –
  • Consists of: Glass tube, AgCl, and reference silver wire.
  • Cotton-Filled Glass Tube – Prevents reaction between AgCl and electrolyte, improving stability and extending lifespan.
• Micro-Volume Measurement –
  • Suitable for NMR tubes and thin test tubes.
  • With a microvolume container (sold separately), measurements as low as 15 μl are possible.

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 micro-volume pH measurements.
