Gel-filled pH sensor

For use in sterile applications, the InPro 3030 gel-filled pH sensor is ideal for use in autoclavable bench-top fermenters and cell culture vessels

Designed specifically for use in sterile applications, the InPro 3030 gel-filled pH sensor represents excellent value for money for the biotechnologist, whether for use in autoclavable or steam-sterilisable fermenters or cell culture systems.

Pressure resistant up to 6 bar the sensor can be used in large scale production vessels where hydraulic pressures and head-space overpressure combines to produce several bar pressure at the sensor level.

Equally the sensor is ideal for use in autoclavable bench-top fermenters and cell culture vessels.

Extended weight gain tests have shown that the new proprietary reference junction used by the sensor eliminates ingress of contaminating media that has dogged other designs in the past.

Diaphragm contamination and blockage by silver sulphide due to sulphur bearing compounds present in most biological media is now a thing of the past thanks to the InPro 3030's patented silver ion-trap.

This high capacity barrier effectively eliminates escape of silver ions from the reference element for the life of the electrode thus greatly prolonging the life of the sensor even in heavily contaminating media.

InPro 3030's robust glass bulb and shaft make it suitable for use without further protection in bench-top autoclavable fermenters and cell culture vessels.

For larger vessel and production use the sensor is housed in an InFit fixed housing or InTrac retractable housing designed for sterile operation.

The measurement system is completed with one of the latest HART compatible transmitters from the extensive Mettler Toledo range.
