Air outlet particle filter for the MAS-100 NT microbial air sampler

The MAS-100 NT microbial air sampler from MBV AG is specified for use in ISO Class 5 and GMP Grade A clean rooms. Construction, surfaces and components are of the highest quality and do not produce significant amounts of particles that contaminate the environment.

However, there are situations where…

Table 1: Experimental set-up for the comparison of the minimal and maximum air resistance configurations of MAS-100 Iso MH: On the left, the set-up of a 2-sampling head configuration of the MAS-100 Iso MH including 1 sampling head attached to a 90° stainless steel bow. 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 MAS-100 MH 4-head air sampler (left graph) and 2-head air sampler (right graph) measured with different resistance conditions: Both the minimal resistance (yellow) and the maximum resistance (blue) measurement values
are within the allowed area of less than 2.5% deviation from the target air flow 100 SLPM (green). The mean standard deviation from the target air flow 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.

Safe remote microbial air sampling with MAS-100 ISO MH

Abstract

Active microbial air sampling is performed in isolators and RABS to detect potential product contamination by airborne microorganisms. Two MAS-100 Iso MH impaction-based microbial air samplers were successfully tested for these applications: (1) sampling air 50 m from the instrument base uni…
