Polymer microparticle suspension, Turbidity Standard
Density (D) 1,01 g/cm³
Boiling point (bp) 100 °C

Turbidity Standard for adjusting the density of a bacterial suspension.
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. The absorption is measured at a wavelength of 625 nm.

The McFarland PMS Standards are equivalent turbidity standards to the original barium sulfate standards. The optimised Polymer Microparticle Suspension (PMS) separates slower than the barium sulfate version.

McFarland PMS 0.5 for microbiology

The McFarland PMS Standards are equivalent turbidity standards to the original barium sulfate standards. The optimised Polymer Microparticle Suspension (PMS) separates slower than the barium sulfate version.


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.

For research use only. Not approved for human or veterinary use, for application to humans or animals, or for use in clinical or in vitro diagnostics.
