Air Outlet Particle Filter For Viable Air Sampler MAS-100 NT®

Introduction

Viable Air Samplers are used for quantitative determination of airborne contamination in cleanrooms and isolators. To maintain the cleanliness of the environment, the air flow should neither disturb the unidirectional air flow nor pose a contamination risk to the environment.

As portable…

Continuous airborne microbial monitoring in critical environments

Summary

For more than 10 years, cGMP guidelines have emphasized expectations regarding continuous microbiological process air monitoring in Class A (ISO 5) and Class B (ISO 7) areas, referring to the sedimentation plate method. However, since they rely on gravity-driven particle settling on a surface…

Table 1: Experimental setup for the comparison of the minimal and maximum air resistance configurations of MAS-100 Iso MH: On the left, the setup of a 2-sampling head configuration of the MAS-100 Iso MH including 1 sampling head attached to a 90° stainless steel bend. On the right, the identical instrument with an additional 50 m tubing and an air filter between the sampling head and the base unit.

Figure 1: Calibration results of the MAS-100 MH 4-head air sampler (left graph) and 2-head air sampler (right graph) measured under different resistance conditions: both the minimal resistance (yellow) and the maximum resistance (blue) measurement values are within the permissible range of less than 2.5% deviation from the target airflow of 100 SLPM (green). The mean standard deviation from the target airflow is -0.25% for the 4-head device and -0.35% for the 2-head air device.

Figure 2: Schematic of a possible 4-head configuration of the MAS-100 Iso MH microbial air sampler: 3 sampling heads are positioned within the isolator/RABS and one head is placed outside as an external calibration point. The length of the tube/pipe (gray, dotted line) is specified to 10 m. In this experiment, we tested a 50 m tube and additionally integrated an air filter (gray, dotted line). The airflow (blue) starts at the sampling head and is directed through the air filter, the extension tube/pipe, and the outer and inner valves to the base unit. The latter contains an airflow sensor that controls the blower speed.
