BioBall® contains a precise number of microorganisms in a water soluble ball delivering unprecedented accuracy for Quantitative Microbiological Quality Control.
BioBall® is available in three standard levels –
SingleShot - mean of between 28 and 33 cfu with a standard deviation of 3 cfu or less (unless otherwise stated). Designed for a precise single inoculation. Ideal positive control for media QC, positive control for pathogen testing in the food industry and as a positive control for water and waste water testing.
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 x 100μL doses of 50 cfu. Ideal for pharmaceutical microbiology QC where multiple positive controls in the 10 to 100 cfu range are needed.
HighDose 10K - mean of between 8,000 and 12,000 cfu with a standard deviation of ≤ 15% of the mean (unless otherwise stated). Designed for a single precise inoculation at a higher cfu level. Ideal positive control food for testing where a higher cfu inoculation is required.
BioBall® is easy to use. It requires no preparation or pre-incubation. It can be added directly to media or matrix samples.
BioBall® is an accredited reference material under ISO Guide 34 standard.
