The stability of McFarland Latex Standards allows for a significantly longer shelf-life, better uniformity, and less clumping
The McFarland Latex Standards are prepared from suspensions of uniform latex particles with similar absorbance values as the original barium sulfate standards. Equal obliteration or distortion of contrasting black lines on the white background indicates a turbidity match. The Hardy Diagnostics manufacturing facility and quality management system comply with the FDA's Good Manufacturing Practices (GMP) and have achieved ISO 13485 certification as a medical device manufacturer.
