SpinTrode Details

The SpinTrode pH sensor is a top choice for researchers requiring high precision in microvolume pH measurements. This specialty pH electrode yields exact pH measurements in small sample volumes, making it ideal for applications such as NMR tube analysis. Its ultra-thin 3 mm shaft and extended 180 mm length enable easy insertion into narrow containers while requiring only a 7 mm immersion depth to obtain accurate measurements. 

The robust glass body and ceramic diaphragm enhance chemically inert durability and reliability across pH measurements from 0 to 14 and temperatures between 0 ºC and 100 ºC. Featuring a refillable design with Hamilton’s Everef reference system, it ensures stability, longevity, and reduced drift over time. 

Finally, the SpinTrode’s universal S7 connector allows seamless compatibility with a variety of laboratory meters and instruments.

Ideal for pH measurements in NMR tubes and other long, slim sample containers.

High pH measurement accuracy with long-term stability.

High-performing pH sensor attributes

  • Accurately performs across the full pH spectrum and temperatures between 0-100 ºC.
  • Rugged and reliable glass body and ceramic diaphragm reduce the risk of signal drift.
  • Everef reference system aids consistent pH performance.
  • S7 connector head to facilitate seamless device integrations.

Ultra-slim, long configuration

  • SpinTrode has an extended 180 mm a-length with a thin 3 mm shaft diameter.
  • Requires only 7 mm immersion depth to conserve sample sizes.
  • Specialized for NMR tube-based pH measurements.
     

  • Hamilton pH sensors are characterized by their high measuring accuracy and long service life.

    Hamilton pH sensors are characterized by their high measuring accuracy and long service life. This contributes significantly to the control of our processes. They also help us to guarantee the required product quality and to further optimize processes.

  • We particularly appreciated the professional and personable approach.

    The training on pH sensors was highly beneficial for us. After a detailed introduction to the fundamentals of pH measurement, electrode measurement principles, and the topic of troubleshooting/prevention, we had sufficient time to ask our specific questions. This enabled us to apply what we learned immediately and integrate it directly into our laboratory routine. We particularly appreciated the professional and personable approach of Mrs. Näf-Rüdiger, who guided us through the informative and application-oriented training session.
