PyroScience is a manufacturer of high-precision optical sensors based on unique optical detection techniques (REDFLASH technology).

The product line includes various fibre-based and smart contactless sensor heads for compact PC-operated and stand-alone read-out devices for measurements in gas, water, aqueous and semi-solid samples. Sensor systems are also available for challenging measurements in organic solvents, microfluidics and high-throughput screening and for various OEM applications, such as oxygen gas monitoring, underwater/deep sea applications, and many others.

We offer unprecedented multi-parameter solutions for applications in e.g. life sciences, experimental biology, aquatic sciences, biotechnology, bioprocessing, microbiology, water- and wastewater-treatment, aquaculture, marine research, or environmental monitoring.

The sensor tip of these fiber-optic oxygen mini- and microsensors is glued into a stainless needle. The complete sensor is resistant to corrosive environments (e.g. seawater), because all metallic parts are made of stainless steel. The following sensor types are available:

OXF500PT and OXF900PT: The very sensor tip is positioned exactly within the bevel of a bevelled needle tip giving mechanical protection. This type is especially designed for performing oxygen measurements in gas samples after sensor insertion through rubber septa or packaging material (paper, plastics, aluminium packages). The needle is filled with glue ensuring no air leakage through the needle when puncturing packaging material. The OXF500PT is recommended for measurements in the gas phase and for insertion through thin septa or packaging material. The OXF900PT has a thicker needle applicable for thicker septa or packaging material. Application in liquids is also possible, but requires special precautions in order to remove “trapped” gas bubbles at the sensor tip.

OXF50 and OXF1100: The fragile sensor tip extends ca. 6mm (OXF50) or 2mm (OXF1100) from a straight-cut needle. They can be applied in liquids and in gases. The complete inner space of the syringe needle is carefully filled with glue, minimizing any gas reservoir which might slow down the repsonse time of the sensor.

Trace range versions. Special trace range versions are available for high precision measurements close to 0%O2. They offer about 5x higher resolution compared to the full range oxygen sensors. The recommended measuring range is 0-10% O2. However, a calibration at ambient air (21% O2) is possible, ensuring a straightforward calibration without the need of special calibration standards.
