suitable evaluation of the aseptic environment.
6.1.2 Volumetric Air Sampling:
6.1.2.1 This technique is also known as Active air sampling and used to quantitatively assess the environment and trap the microorganisms associated with light particles in the air of controlled environment that cannot be settle down on Petri plates easily. One cubic meter (1000 liter) of air is sampled in order to maximize sensitivity of technique.
6.1.2.2 Surface Sampling: This technique is used to sample the regular or irregular surface of equipment, facilities, and personnel in aseptic area of controlled environment. Surface sampling can be accomplished by the use of contact plates or by swabbing methods.

6.1.2.3 Contact plate: This method is applicable for sampling of regular or flat surface; a suitable agar surface is pressed against the test surface for a short moment. Thus, part of the microorganisms that colonizing the surface is transferred to the agar surface. Microbial counts are reported as per plate contact plate.
6.1.2.4 Swab method: This method is applicable for sampling of irregular surfaces, especially irregular surfaces of equipment. After sample collection the swab is placed in an appropriate diluents or transport medium and is plated onto the desired agar plate and microbial count are reported as per swab of defined sampling area
6.1.3 Personnel monitoring: This technique is applicable for sampling of garb and Gloved Fingertip Sampling of the personnel associated with aseptic processing. It includes contact plate method for monitoring of garbing and 90mm media filled plate for Gloves Fingertip Sampling.
