OneFerm pH LEVP Details

The Hamilton OneFerm family of pH sensors represents a leading solution for single-use applications within the Pharmaceutical and Biotechnology Industries. These sensors are a significant advancement in single-use measurement, addressing common issues associated with traditional reusable pH sensors inserted into bags. 

Combining the proven reliability and measurement stability of Hamilton's conventional sensors with the convenience of seamless integration into single-use bioreactors, OneFerm sensors offer high accuracy even after gamma irradiation and boast a sufficient shelf life. Their clog-free diaphragm ensures exceptionally low drift throughout the sensor's lifespan, and they can be customized to specific application requirements. 

The OneFerm family is ideal for single-use bioreactors (both bag and rigid container types), single-use mixers, and single-use downstream processes.  

Common applications Pharma & Biopharma, Bioprocess Downstream, Single-Use Bioprocessing, Bioprocess Upstream

Simplified integration of reliable, stable, and accurate pH measurement.

Featuring bio-compatibility, ready-to-use convenience, and a clog-free design.

Market-Leading Single-Use Solution
