- Selection includes high selectivity and low detection limit sensors WPI's biosensors are unique, because they offer a high selectivity and low detection limit (down to nM concentration) with a broad dynamic range, covering physiological concentrations of species with different sizes from nanometer to millimeter. The majority of our sensors are the only commercially available sensors in the world. Scientists across a variety of disciplines have relied on our sensors for over 25 years. These scientists use WPI's sensors for research performed in universities, hospitals, biomedical research labs, pharmaceutical companies, food/nutrition research labs, environmental monitoring centers and military labs. Our popular biosensors are listed in thousands of publications.
- LabScribe is the powerful data acquisition software included with Lab-Trax™ (formerly DataTrax). The acquisition and data display in LabScribe is easy and straight forward. It supports real units and a time-based display that is not coupled to sample rate. You can display up to 1,000,000 data points per channel on the screen. Scrolling, zoom-in and zoom-out tools, together with a searchable list of user interventions, make finding important areas of data easy. And, of course, you can print or export anything that you see.
- Are you looking for electrochemical detection of oxygen using carbon fiber electrodes or fluorescence sensing detectors for optical sensors? We offer several systems for oxygen detection.
- All aerobic and anaerobic life is adapted to survive in a narrow range of oxygen concentration. Oxygen is the terminal acceptor in oxidative phosphylation in mitochondria, the cell's ATP making powerhouse. Oxygen also regulates production of proteins involved in nitrogen fixation in anaerobes, and is required for inflammatory elimination of invading foreign substances such as virus and bacteria by production of reactive oxygen species (ROS). WPI's dissolved oxygen sensors are sensitive linear and enjoy a broad range of application.
- We offer a variety of pH sensors for free radical biosensing applications.
Free Radical Detection and Measurement of Biologically Significant Ions and Compounds - Specializing in Nitric Oxide
WPI has a long history of innovation in the area of ion-specific detection and recording. We have developed biosensors and provided quality tools and instrumentation to life scientists for nearly 50 years.
In 1989 we marketed the first commercial sensor for nitric oxide and have been at the front of the field ever since. WPI maintains strong ties and collaborations with University of Alabama, University of South Florida, Harvard University, MIT, University of California Los Angeles, University College London, University of Cambridge and other institutions around the world.
WPI also has its own fully equipped research and development laboratory staffed by scientists who continually design, develop and produce sensors relevant to the changing requirements of research. We have been the recipients of many federal grants to expand our technology in this area, as well.
Today WPI carries a full range of products that focus on the detection and measurement of biologically significant ions and compounds. Our line encompasses more than 600 products including: electrodes, sensors, calibration solutions, cables, amplifiers and recording electronics. We have everything you need.
Real time detection and measurement of a variety of redox-reactive species is fast and reliable using the electrochemical (amperometric) detection principle employed by WPI's TBR system. This low noise system works with a variety of sensors for detecting nitric oxide (NO), oxygen (O2), hydrogen peroxide (H2O2), Hydrogen sulfide (H2S) and glucose.
