Polyplast Details

The Hamilton Polyplast Lab Sensor is a robust and maintenance-free combination pH electrode featuring a shatter-proof plastic shaft. The sensor utilizes a Single Pore liquid junction that ensures direct contact between the sample and the Polisolve electrolyte, which helps prevent clogging. This design, combined with the Ag/AgCl reference system and Polisolve electrolyte, contributes to reliable performance without the need for regular maintenance such as refilling.

Common applications Pharma & Biopharma, Bioprocess Upstream

Shatter-proof plastic shaft provides durability.

Clogging-free thanks to the Single Pore junction.

Shatterproof Plastic Shaft

  • Constructed from durable plastic, the shaft offers exceptional resistance to impacts and accidental breakage, making it ideal for portable use in the field or in laboratory environments where the risk of damage is higher.
  • This robust design ensures a longer lifespan for the electrode, reducing the need for frequent replacements and providing a cost-effective solution for routine pH measurements.

Single Pore Liquid Junction

  • The Single Pore liquid junction design ensures direct contact between the sample and the Polisolve electrolyte.
  • This feature is key to preventing clogging, enabling reliable and fast measurement results even in complex or viscous samples.

  • 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.

FAQ

What is a polymer-filled sensor and why would I choose it?

Polymer-filled sensors use solid (or nearly solid) electrolyte. This design keeps electrolyte from flowing out of the sensor and process liquid from poisoning or clogging the sensor. Polymer filled sensors are a great choice for industrial applications with strong chemicals, particulates and elevated pressures.
