Beschreibung
McFarland BSS 0,5, for microbiology, Density (D) 1,01 g/cm³, Boiling point (bp) 100 °C, Storage temp. +15 to +25 °C
The cell density is adjusted in the simple comparison to the standard. This can be directly performed visually or by measuring with a spectrophotometer.
The turbidity value of the standard of 0,5 MFU (McFarland Units) corresponds to approximately a culture density of 1,5 x 108 cells/ml. This cell density is specially needed as bacterial inoculum for the antibiotic susceptibility test.The absorption is measured at a wavelength of 625 nm.
The McFarland BSS Standards are used as turbidity standards since 1907 to produce an expected reproducible cell density of a bacterial suspension.
