In pharmaceutical manufacturing, Laminar Air flow cabinet provides which class of clean air in aseptic technique:
Show Hint
LAF = Aseptic = Class 100.
Updated On: May 15, 2026
- Class-10
- Class-100
- Class-1000
- Class-10000
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Cleanroom classifications (like US FED STD 209E) define air quality by the number of particles allowed per cubic foot.
Step 2: Meaning
Aseptic techniques require environments with minimal particulate and microbial contamination to protect the product.
Step 3: Analysis
A Laminar Air Flow (LAF) cabinet uses HEPA filters to provide a localized environment. For aseptic filling and handling, a Class 100 (Grade A) environment is required, meaning no more than 100 particles of 0.5 microns or larger per cubic foot.
Step 4: Conclusion
The standard class for an LAF cabinet in aseptic manufacturing is Class 100. Final Answer: (B)
