PreSens Sensor Spot, non invasiv O2 sensor

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 O2 concentration.

for shake flask, tubes, petri dishes and cultivation bags. O2 measurement without contact.

advantages

• non invasiv
• no sampling necessary
• calibration free
• can be delivered sterilised by beta irradiation

specifications

• O2 range: 0 to 100 % with sensor type PSt3, 0 to 4.2 % with sensor type PSt6
• respons time: 6 to 40 s
• temperature range: 5 to 50 °C

Micro O2-probe

sensor tip diameter smaller as 150 um

no need of reference electrode

different types

• needle type, optimal for penetration in tissues, septum rubber. After penetration, he sensor tip is extended for measurement
• implantable, only the fiber. As it is metal free, it can be used in NMR environnement

applications

• measurement of O2 in animal and plant tissues
• measurement in small volumes or small headspace of package

specifications

• O2 range: 0 to 50 % with sensor type PSt3, 0 to 3 % with sensor type TOS7
• respons time: 1 to 39 s
• temperature range: 5 to 50 °C

O2-probe

The oxygen probe for in-line measurement consists of a fitting made of stainless steel with an optical exchange cap. The in-line measurement is connected to the instrument via an optical fiber. It has a standardized thread and length and is compatible with most bioreactors and port adapters. In addition, customized fittings for e. g. sight glasses are offered

specifications

• O2 range: 0 to 100 % with sensor type PSt3, 0 to 4.2 % with sensor type PSt6
• respons time: 6 to 40 s
• temperature range: 5 to 50 °C
• can be sterilized at 130 °C

detects O2 in multidishes non-invasively. These contain a sensor spot at the bottom of each well. They are read out non-invasively through the transparent bottom. It is available in the 24-well and 6-well format. It can be used in incubators and on shakers and is thus the ideal tool for cell cultivation.
