Holbach - Model LKS 30 & LKS100 -Air Sampling System
Our air sampling heads are ideally suited for the sampling of cultivable particles onto culture media. For operation in industrial and health care applications as well as expert surveys, they reliably deposit particles of the sampling air into standard Petri dishes. Two versions are available: LKS100 and LKS 30 rated with 100 l/min and 30 l/min, respectively. The air sampling heads work by the round-jet impaction principle.
The air sampling heads LKS 30 and LKS100 are operated with the battery-powered sampling system MBASS30V3.
The performance features of the LKS100 and LKS 30 air sampling heads:
- The sampling heads are validated according to EN ISO 14698-1
- The culture medium fixation allows sampling in every operating position
- The hose connection at the sampling intake allows sampling from cavities
- The sampling heads are autoclavable
- The high jet count (500 jets on the LKS100) reduces multiple occupancies with high microbial counts
- The high collection efficiency guarantees that even smallest spores are deposited
The optionally available transverse adapter and suction nozzles allow for isokinetic microbiological sampling at ventilation systems and vertical air outlets.
The optionally available air inlet funnel LET40 allows for hygiene inspections at ceiling air outlets.
The sampling air is drawn from top to bottom through the air sampler. A volume flow is thus evenly created above the jet plate in the top part. The velocity of the air flow is considerably increased within the jet area. Thereby, the airborne particles are accelerated towards the culture medium in the petri dish and impact the medium.
Depending on the viscosity of the culture medium, the high velocity of the air flow leaves visible dents on the culture medium`s surface. These dents correspond to the germination sites.
The loaded culture media are subsequently cultivated and the cultivable portion of the sample can be determined.
