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 new optical temperature sensors from PyroScience are based on an innovative technology utilising temperature-sensing properties of luminescent indicators. The combined respiration vials have an integrated optical temperature and oxygen sensor for contactless measurements in gaseous or liquid samples. The ready assembled respiration vials with integrated optical temperature and oxygen sensor stripes are available with a volume of ca. 4mL (TOVIAL4) or with ca. 20mL (TOVIAL20). Separately available adapter rings ADVIAL4 and ADVIAL20 allow for easy fixation of optical fibers connecting the respiration vials to the FireStingO2 optical oxygen meter from PyroScience. The elongated shape of the sensors allows simulatenous oxygen and temperature measurements at different heights within the vial by simply sliding the adapter rings up and down. The optical temperature sensor in the combined respiration vial can be used for true temperature compensation of the integrated oxygen sensor for high precision measurements.

Application Examples. True temperature-compensated respiration rate measurements of bacteria or cell cultures, oxygen production/consumption rates of microalgae, general metabolic rate measurements, respiration rate measurements of eggs, larvae or small fish etc.

  • Vials with ca. 4 ml or ca. 20 ml
  • For small scale respirometry or metabolic rate measurements
  • Track oxygen levels in the liquid phase and simultaneously in the gaseous headspace
  • Measures simultaneously temperature and oxygen in gas or water
  • For true temperature compensation of the oxygen measurement
  • Lids with septum
  • No oxygen consumption
  • >3 years shelf time
