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
· Oxygen measurement in gases and liquids
· Non-invasive online pH, CO2 and oxygen measurement
· Oxygen and pH sensors for single-use bioreactors
· Microsensors for pH and oxygen
· Process control in shake flasks incl. biomass monitoring
· 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
Oxygen Flowthrough Cells
