Description
HA.s.ex.20.5 Exner biomass sensor is a near-infrared (NIR) probe intended for continuous determination of total biomass in laboratory-scale bioreactor cultures. It features a 20 mm optical measuring path and is matched to 5-litre bioreactor vessels, allowing operators to follow biomass development throughout fermentation or cell-culture runs. By using NIR spectroscopy, the sensor provides non-invasive insight into overall biomass levels and reduces reliance on repeated offline sampling. Delivered as a single unit, the HA.s.ex.20.5 Exner biomass sensor from manufacturer IKA fits bioprocess and laboratory analytics environments where stable, vessel-matched biomass monitoring is required. It is classified among laboratory materials for process measurement and supports research groups working with mid-scale 5 l systems. The combination of a 20 mm path length and dedicated 5 l vessel suitability helps ensure appropriate optical geometry for the culture volume in use. This makes the sensor a clear option when selecting NIR biomass probes for five-litre bioreactor setups in development and routine laboratory applications.

Questions about HA.s.ex.20.5, Exner biomass sensor, 20 mm, for 5 l
What is this article?
HA.s.ex.20.5, Exner biomass sensor, 20 mm, for 5 l is the article on this page. Luminix Health distributes IKA for laboratory use. It sits in Temperature probes & sensors, inside Temperature measurement, in Lab instruments.
A temperature probe is the sensor, Pt100, thermocouple or thermistor, that a meter or a logger reads. The probe, not the display, is what is calibrated. The sheath material and the response time matter in a liquid versus a block.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
