We also test products in water-based, multi-dose topical and oral dosage forms, as well as drug dosage forms including ear, eye, rinse, nasal and dialysis solutions.
We perform antimicrobial effectiveness testing for method suitability and routine testing. Our bioburden testing capabilities include:
Membrane filtration method: a quantitative technique that uses membrane filters and vacuum to isolate bacterial and fungal colonies from fluid samples.
Standard Plate Counting / Inverted Plate Method: Isolation of bacteria and fungi by spreading sample preparations onto Petri dishes and adding nutrient agar that allows the growth of any microorganisms present.
Diffusion plate method: isolation of bacteria and fungi by spreading sample preparations onto nutrient agar plates.
