Single-use Dissolved Oxygen Sensors

Single-use oxygen sensors (or single-use dissolved oxygen sensors) are sensors for DO measurement that are designed to be integrated into single-use bags by the bioreactor bag manufacturer. METTLER TOLEDO single-use DO sensors measure the oxygen concentration by an optical measurement principle and can be used in a wide range of bioprocessing applications that require dissolved oxygen measurement inside single-use bags. With their robust design for optimal process safety, METTLER TOLEDO single-use optical DO sensors ensure long-term stability for use throughout an entire batch while offering an output signal identical to that of a reusable sensor. All wetted polymer materials are made of USP 88 VI certified materials.

Single-use oxygen sensors are directly integrated into the single-use bag (SUB) by the bioreactor bag supplier and cannot be taken out and replaced. The complete SUB assembly with the single-use DO sensor is gamma irradiated and is shipped pre-sterilized to the biopharmaceutical producer. Consequently, integrated single-use oxygen sensors will never be removed from the reactor and will also never be autoclaved.

The InSUS 607 by METTLER TOLEDO is a single-use DO sensor designed for integration into single-use bags. This single-use oxygen sensor uses optical technology to provide fast, accurate dissolved oxygen measurements. The shelf life is 36 months dry storage and the disposable DO sensor is made of USP 88 VI certified materials to ensure the highest process safety.

METTLER TOLEDO sells single-use sensors directly to bioprocess equipment manufacturers for integration into their single-use devices. These sensors are not directly sold to end users.  If you are interested in single-use pH sensors or single-use dissolved oxygen sensors for your manufacturing operation, contact your bioprocess device manufacturer and ask them for METTLER TOLEDO InSUS single-use sensors.
