The particle sampler PS 30 captures the total spore content (cultivable and non-cultivable) in the air.
With particle sampling, the flow through a slot jet is used to make airborne particles to impact onto a transparent adhesively coated object slide. The particles are deposited in a compact sampling track 1.1 mm wide and 16 mm long.
The loaded slide can be stained directly after the sampling (without cultivation) and evaluated using a light optical microscope. In contrast to airborne spore sampling, the germination capacity of the particles is not relevant to the result, since each spore is detectable and countable in the microscope. Thanks to the high collection efficiency of the particle sampler, even agglomerates and aggregates of bacteria can be detected and counted.
In addition, particle sampling also reveals very fast information about non-microbiological disturbances in the air such as fibers, inorganic particles (e.g. abrasive particles from production facilities).
The particle sampling head is operated with our convenient MBASS30 or with a separate pump.

The performance specifications of the PS 30 particle collector:

• Detection even of non-cultivable spores and particles
• Collection of spores, pollen, fibers, dandruff and other micro-particles in air and gas on adhesively coated microscope slides
• Up to 3 samplings on a single slide because of adjustable slot jet
• Sampling from all operating positions thanks to slide fixation
• Sampling out of cavities via hose connection to the sample air intake
• Same operating volume flow of 30 l/min as the LKS 30 air sampler and FA 30 filter adapter
• No cultivation time – evaluation possible immediately after sampling
• No temperature and time restrictions for sample transport
• The method conforms to the VDI (German Association of Engineers) Guideline 4300 part 10
