Air samplers

Coriolis Air samplers are dedicated to the collect of biological particles in the air which bring new perspectives for the control of airborne contamination thanks to its liquid sample.

The Coriolis was developed to go beyond traditional techniques performances of air bio-contamination control.

Traditional techniques indeed rely on the impaction of particles on a solid agar medium and are thus limited by low flow rates, unreliable impaction and a longer analysis time. They are also restricted to cultivable flora studies.
In contrast, the wet walled cyclonic Coriolis rapidly collects and concentrates biological particles into liquid at a high air flow rate (300 lpm).

The sample liquid output is then compatible with a number of Rapid Microbiological Methods (RMM) including PCR, immunoanalysis, flow cytometry… and reliable results can be obtained in only few hours! This new technology allows to obtain good efficient results even when the concentration of target particles is low or when events occur unexpectedly. This range of equipment answers to the requirements of air quality control and biosurveillance.


Maintaining yeast viability during tissue homogenization

The CNRS UMR-5234 is working on yeast of medical interest belonging to the genus Candida. The aim was to homogenize tissues containing the yeasts without lysing them.

An adapted protocol using the Minilys® homogenizer combined with the appropriate lysing kit allows to disrupt samples as liver, brain, kidney etc. in maintaining yeast viability.
