Mettler Toledo pH Probe InLab Routine pH Electrode with Solution

Mettler Toledo 51343050 InLab Routine pH Probe – 0 to 14 pH, Refillable Glass Body

The Mettler Toledo 51343050 is a premium, combination pH electrode engineered for highly accurate and repeatable measurements in standard laboratory applications. As part of the InLab Routine family, this probe features a robust glass body and a refillable liquid electrolyte system ($3\text{M } KCl$), ensuring a rapid response and an exceptionally stable junction potential. The sensor utilizes a classic S7 screw-cap connector, providing the flexibility to be used with a wide variety of meters via detachable cables. Whether you are performing routine quality control, environmental testing, or complex R&D titrations, the 51343050 delivers the chemical resistance and longevity required for demanding analytical workflows.

Technical Performance and Design

• Refillable Liquid Electrolyte: Unlike maintenance-free gel sensors, this probe utilizes a refillable $3\text{M } KCl$ bridge. This allows for a continuous, high-flow rate of electrolyte through the junction, which results in faster stabilization times and prevents the junction from clogging in "dirty" or complex samples.

• High-Quality Glass Shaft: The chemically resistant glass body is ideal for use with aggressive solvents and high-temperature samples where plastic-body probes might fail or leach contaminants. The glass also allows for easier cleaning and decontamination.

• Long-Life Comparison System: Features the advanced Argenthal lead-off system with a silver ion trap. This technology ensures that the electrolyte remains free of silver ions, preventing junction silver-sulfide fouling and extending the operational lifespan of the probe.

• S7 Screw Head: The universal S7 connector allows for easy cable replacement or the use of different cable lengths, ensuring compatibility with almost any pH meter brand while maintaining high signal integrity.

Key Benefits & Applications

• Analytical Precision: The absolute standard for aqueous buffer preparation, media formulation, and general analytical chemistry where a high degree of precision (±0.01 pH) is required.

• Fast Stabilization: The liquid junction is perfect for samples with low ionic strength or varying temperatures, where gel probes often suffer from drift and slow response times.

• Sustainable Service Life: Because the electrolyte can be replaced and the junction cleaned, this probe offers a significantly longer service life than disposable gel-filled electrodes, making it more cost-effective for high-volume labs.
