The LabSen® 241-6 semi-micro pH electrode from Apera Instruments is designed for precise pH measurement in small-volume samples (≥0.2 ml) and thin test tubes. Manufactured with Swiss sensor technology, this electrode features a long-life reference system, a low-resistance glass membrane, and a stable blue gel electrolyte, ensuring high accuracy and durability.

Key Features:

• Swiss Sensor Technology – Ensures precise and reliable pH measurements in small samples.
• LabSen S-Type Semi-Micro Glass Membrane –
  • Length: 100mm
  • Diameter: 6mm
  • Low Membrane Resistance (<350MΩ) for improved response speed and stability.
  • Temperature Compatibility: 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, enhancing stability and extending lifespan.
• Micro-Volume Measurement –
  • Suitable for samples ≥0.2 ml.
  • With a micro-container (sold separately), measurements as low as 60 μl are possible.
• Blue Gel Electrolyte –
  • Does not flow and prevents air bubbles, ensuring consistent measurements.

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 small-volume pH measurements.
