Description
They are attached to the inner surface of any transparent vessel. Differents dyes are included in a matrix. A detector measures the modification of the fluorescence emmited from the dye depending on the pH.
for shake flask, tubes, petri dishes and cultivation bags. pH measurement without contact.
Advantages of the pH spots
- non invasiv
- no sampling necessary
- calibration free
- can be delivered sterilised by beta irradiation
Specifications of the pH spots
- pH range: 5.5 to 8.5
- respons time: 30 s
- accurancy at pH=7: 0.05 with sensor calibration, 0.1 with batch calibration
- temperature range: 5 to 50 °C
Transmitters to use with the pH spots
pH-1 mini: a precise single-channel, temperature compensated pH meter. It is used with pH sensors based on a 2 mm optical fiber. A PC is connected to run the easy-to-use software. On top, analogue outputs and a trigger input are integrated.
pH-4 mini and pH-10 mini: 4 and 10 channels version
