Quantitative method: Sampling by contact agar on plane surfaces.
Surface sampling by contact application with Count-Tact® range.
For unprotected areas
- For Total Flora: Count-Tact Agar (ref. 43501 - 20 x 65 mm plates)
- For Yeasts & Molds: Count-Tact Sabouraud chloramphenicol (ref. 43580 - 20 x 65 mm plates)
Count-Tact Applicator (ref. 96300 - 1 unit)
Standardization of sampling: 10 sec. under a pressure of 500 g
Bi-Box for Count-Tac plates (ref. 96301 - 1 x 10 units)
For protected areas (e.g. ISOLATOR)
- For Total Flora: Irradiated Count-Tac 3P Agar (ref. 43691 - 20 x 65 mm plates)
- For Yeasts & Molds: CIrradiated Count-Tact Sabouraud dextrose 3P (ref. 43812 - 20 x 65 mm plates)
For Total Count: incubate Count-Tact plates up to 3 days at (30 ± 1°C)
For Yeasts & Molds: incubate Count-Tact plates up to 3 days at (22.5 ± 2.5°C)
Count the colonies per plate (25 cm2) and report the result in CFU per cm2
