McFarland Standards for Calibration (16mm Tube) Set of 5

The McFarland Standards for Calibration Set from Hardy Instruments provides a reliable and easy-to-use reference for calibrating Densitometers used in microbiological testing. This set includes five 16 mm diameter glass tubes, each filled with a solution representing a specific turbidity level (0.5, 1.0, 2.0, 3.0, and 4.0 McFarland units). These standards simulate bacterial concentrations and are essential for ensuring accurate and consistent turbidity measurements.
Designed for compatibility with Spectrophotometers  and Densitometers such as the DEN-1 and DEN-1B, the tubes help verify instrument performance and support standardization across laboratory procedures. The 16 mm size ensures proper fit and optical alignment.
Ideal for clinical, research, and industrial microbiology labs, this calibration set supports precise bacterial quantification, helping maintain quality control and reproducibility in microbial testing workflows.
