To observe the laminar flow in a water balloon, a square piece of tape is pasted on its surface. Editable Pharmaceutical Documents in MS-Word Format. Scan the down stream side of the filter with an appropriate photometer probe at a sampling rate of at least 1 ft. By continuing to use the site you agree to our privacy policy. Objective: Non availability of machines/Area These criteria are intended to reduce the risk of microbiological, particle, and pyrogen contamination. The differences between the grades; Their ISO Class equivalent at rest/in operation; . 6.6 Record of LAF filter cleaning Annexure -6 Position the smoke generator and introduce PAO smoke into the air stream, ahead of the HEPA filters, at the concentration of 80 100 mg per liter of air at the filters designed air flow rating and set the instrument at 100% concentration. Cleanrooms in pharmaceutical industry maintain particulate-free air through the use of either HEPA or ULPA filters employing laminar or turbulent air flow principles.
