Oxoid Turbidometer for Microbial Inoculum Standardization to 0.5 McFarland Standard

The Oxoid Turbidometer is a precise instrument designed for microbial inoculum standardization according to the 0.5 McFarland turbidity standard. This optical device enables rapid and accurate adjustment of inoculum density, essential for applications in microbiology, molecular diagnostics, and biotechnology workflows such as molecular cloning and bioprocessing where consistent sample turbidity is critical.

Key technical features include:

• Calibration based on the standardized 0.5 McFarland turbidity reference
• Visual feedback system: _green light_ confirms correct inoculum density, _orange light_ signals incorrect levels
• Compact footprint with external dimensions: 13 x 18 x 9 cm (W x D x H) for benchtop lab use
• Wide voltage compatibility: 100–240 V with 400 mA current ensures global usability

The Oxoid turbidometer is widely adopted in clinical diagnostics and synthetic biology research due to its reliability in ensuring consistent microbial cell density, which is critical for reproducible results in antimicrobial susceptibility testing, biomedical engineering experiments, and biomanufacturing quality control. Its ease of use supports high-throughput environments and is essential for laboratories focusing on biotechnology-driven molecular biology and microbial culture standardization.
