Designed Specifically to Meet Your Single-Use Requirements

Our single-use sensors combine the reliability and measurement stability of our long-term proven conventional sensors with the ease of use as an integral part of the bioreactor. The sensors retain high accuracy performance even after gamma irradiation and offer a sufficient shelf life, making them the ideal single-use solution.

One Vendor, All the Measurements

Hamilton has worked closely with single-use bag manufacturers to understand the market needs.

Wide Variety of Measurements

Whether media prep, mixing, or cell culture, each application has different sensing requirements. Hamilton’s reusable measurement technologies
have been adapted for single-use bag installations.

Designed for Your Needs

There are no accordion-style insertion devices or probe assemblies that must be autoclaved. Single-use sensors come with either weld-in style measurement elements or work with industry standard port fittings. All products can be gamma sterilized with the bag prior to use.

Solutions for Single-Use Bioreactors

Technology You Can Trust

Reliable glass membrane pH technology offers a proven measurement with broad range and very low drift after wet-in. The OneFerm is available in lengths from 70 to 425 mm so that your entire bioreactor product family can be outfitted with single-use specific pH sensors.

The unique S2 optical DO cap mounts on an insertion tube from the bioreactor headplate. It uses the same technology as the industry leading VisiFerm Optical DO sensor.

General Requirements for All Sensors

  • 3rd party test data available for review
  • Packaging suitable for clean room environments
  • All sensor elements are pre-calibrated for manual input; No shift due to gamma irradiation

How Do I Purchase Single-Use Sensors?

Hamilton single-use sensors are currently only available to integrators such as bag, bioreactor, and downstream skid manufacturers.

  • Bioreactor, bag, and downstream skid manufacturers are encouraged to contact Hamilton to discuss integration opportunities.
  • End-users at biopharmaceutical companies are encouraged to ask their single-use solution provider if Hamilton sensors are available for their installation.
