PreSens Oxygen Sensor

一. Company Profile

Based on research activities started in the 1980‘s at the University of Regensburg, Germany, PreSens Precision Sensing GmbH was founded in 1997.

The company combines long-time experiences of different researchers in the fields of electronic engineering and sensor development. Right from the beginning, microsensor systems were sold to customers in life sciences. Already in its first decade of operation PreSens became one of the leading companies in the field of chemical optical sensor technology. Together with its partners it offers full service in Europe, America and Asia.

二.  Prensens Products

PreSens offers a broad range of sensor systems for end users in Biotech & Pharma, Life Sciences, Biological & Environmental Research, the Food & Beverage industry as well as other industrial and technical applications.

We offer systems for

·        Low-maintenance DO measurement for fermentation and bioreactor systems

·        Online oxygen and pH measurement in disposables like multiwell plates and plastic bags

·        Imaging solutions for 2D-mapping of oxygen-, pH-, and CO2-distributions

Characteristics of PreSens sensors

Non invasive measurement (non-invasive measurement)

No drilling or sampling: avoid oxygen entry and carbon dioxide emissions (accurate measurement)

Does not cause oxygen consumption

Non glass product probe, no risk of breakage

Signal measurement is independent of flow velocity

1.  Optical Oxygen Sensors & Meters

Variety of sensors for industrial and scientific applications

 µL up to m3 range

 Pre-calibrated Insertion in plant and animal tissue

 For microbial and cell culture

Oxygen Meters:  Single- and Multi-channel Devices for Precise Oxygen Measurements

Non-invasive Oxygen Sensors

 The non-invasive optical oxygen sensors measure the partial pressure of both dissolved and gaseous oxygen. They are fixed on the inner surface of the transparent glass or plastic material. The oxygen concentration can then be measured in a contactless and non-destructive manner from outside, through the wall of the vessel. Different coatings for different concentration ranges are available

Online monitoring without sampling 

 Applicable from microliter scale to production scale 

Contactless & non-destructive measurement 

Pre-calibrated & ready-to-use 

Integrated in disposables 

 For bags & single-use bioreactors 

 For PET & glass bottles

Examples for Applications
