Based on the contactless sensor technology, PyroScience offers ready assembled respiration vials with integrated sensor stripes for oxygen (also in combination with temperature sensors). The glass respiration vials have screw caps with a septum, and are available with ca. 4mL (uncalibrated) volume. Adapter rings allow an easy fixation of optical fibers for read-out with optical oxygen meters from PyroScience for incubations in closed vials and/or respiration rate measurements. The elongated shape of the sensor spots allows also oxygen measurements at different heights within the vial using several fibers/adapter rings in parallel.
Standard range. This sensor is specified for an optimum measuring range of 0 to 500 hPa oxygen (0 -250% air saturation). However, without specifications, it is possible to measure in up to 1 bar pure oxygen/100% oxygen saturation/100% O2. For detailed specifications, see the respective pdf file in the Downloads tab.
Optical isolation. For applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples, an additional optical isolation (-OI) protection layer is added to the sensor surface to avoid interferences with the measurements.
Easy calibration. A simple ambient air calibration can be performed with a few clicks (<1 minute for equilibrated setup). For precise oxygen measurements close to 0% we also offer easy-to-use calibration capsules (OXCAL). Simply dissolve the content of one calibration capsule in 100 ml distilled water, wait 10-15 minutes, perform the 0% calibration and start measurements with a calibrated sensor. For detailed calibration recommendations refer to the manual in the downloads tab.
Standard stock item. This item is typically in stock and small numbers can be shipped quickly. This does not apply for larger amounts, which ship with standard delivery time.
