Vertical Laminar Flow Hood Aseptic Technique

The direction of air flow may be horizontal or vertical.

Vertical laminar flow hood aseptic technique.

Cytotoxic agents radioactive agents antimicrobial agents. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. Manipulative technique is also different in a vertical flow hood. T f using a laminar flow hood in an open room is no safer than preparing products on a countertop.

Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units. Provide a constant flow of air out of the work area to prevent room air from entering. Provide clean air to the working area. Use precautions to minimize contamination in the product preparation area.

Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Supplies may be arranged to the sides and the back of the area in which manipulations will be performed. Vertical laminar flow hoods are often chosen because they resemble on a small scale the design of a laminar flow cleanroom in which fan filter units are typically positioned in the ceiling. While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product.

99 99 particle free air is forced downward toward the work surface. What is the maximum number of particles in a clean room buffer room and ante room. Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. Use strict aseptic technique to avoid introduction of contaminants into the hood.

Items not sterile including fingers and hands must be kept. Horizontal flow hoods are most commonly used with the more costly vertical flow hoods being reserved for agents that may produce an environmental hazard e g. Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2.
