As the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. Particles tend to run in straight lines and adhere to surfaces (agar plates) directly in their path. The impactor design allows viable particles, flowing in straight lines, to accelerate through the slits at an optimal flow rate. This results in viable particles captured at a high biological efficiency.
