描述: BioBall® contains a precise number of microorganisms in a water soluble ball delivering unprecedented accuracy for Quantitative Microbiological Quality Control. BioBall Multishot 550 – mean of between 500 and 600 cfu with a standard deviation of ≤10% of the mean. Designed for re-hydration into 1,1 ml of MultiShot 550 Re-Hydration Fluid to provide 10×100 µl doses of 50 cfu. Ideal for pharmaceutical microbiology QC where multiple positive controls in the 10 to 100 cfu range are needed.
BioBall MultiShot 10e8 – mean of between 0.7 and 1,5×108 cfu with a standard deviation of ≤20% of the mean. Designed for rehydration into 1,1 ml of BioBall Re-Hydration Fluid to provide 10×100 µl doses of 107. Pharmaceutical and cosmetic preparations often require antimicrobial activity to prevent microbial proliferation or to limit the effects of contamination. The Pharmacopoeias require testing these products for the efficacy of antimicrobial preservation (e.g. USP 51, EP 5.1.3, JP19). BioBall MultiShot 10E8 is ideal for this application and simplifies preparation and provides a precise inoculum.
