Availability:

This kit with pH patches, factory tested and applied to cuvettes, turns your visible wavelength spectrometer and light source into a non-invasive pH probe. The kit consists of a fiber attached to a sample holder, light source and spectrometer.

The reflective pH patches coatings are capable of monitoring pH 5 – 9 in liquids. Applications for this kit include bioreactor monitoring (such as fermentation) and process line monitoring.

  • Recommended for use with spectrometers configured with a 50 – 100 μm slit.
  • Both light source and spectrometer must measure 620 nm and either 510 nm or >750 nm

Items Included in REFLECT-PH-KIT Kit:

Item Description
PH-BCG-REFLECT 5-pack of reflective pH sensing patches attached to cuvettes
CUV-UV Cuvette holder
RE-BIFBORO-2 Randomized bifurcated probe assembly
