Bactair Culture Media Plate

Sartorius, 14320-110----ACD, Bactair Culture Media Plate, Total Count, Tryptic Soy AgarBACTair™ culture media plates are ready-to-connect prefilled agar media plates for microbiological air monitoring using the AirPort MD8 air sampler (impaction method). Airborne microorganisms are directly captured on the culture media plates, where the plates function directly as collection heads. This means that the collection properties are integrated right into the culture media plates. With BACTair™, there is no longer a need for metal sieve plates or metal collection heads, which demand regular sterilisation for routine sampling. The geometry of the culture media plate with its 400 holes yields exceptional sampling efficiency.The Tryptic Soy Agar (TSA) medium is used for the recovery of a broad range of heterotrophic microorganisms such as common aerobic and facultative anaerobic bacteria.Optimized GeometryThe number of impaction-holes and their accurate positioning are key to reliable results.Correction FactorsThe recovery of colony-forming units depends on the number of holes in the sieve plate onto which the air is impacted. The lower the number of holes, the higher is the risk that more than one microorganism will pass into one single hole (colony overlapping). BACTair™ operates with 400 air impaction holes. A correction factor is only relevant with very high CFU counts.Evaporation EffectsDuring the sampling period, agar media may dry out, thus inhibiting the growth of the collected microorganisms. The weight of several BACTair™plates was measured prior to and after sampling and compared to other impaction agar plates or strips. Because of its optimal design, BACTair™ shows the lowest desiccation effects and enables viable microorganisms to grow under optimal conditions.FeaturesIndividually, sterile packagedIntegrated disposable sievePre-filled with agar mediaSamples 1m³ in 8 minutesOptimized geometryUnit of MeasurePack of 10 pcs.
