Mindray TDR-Z200 Microbe Turbidimeter

The Mindray TDR-Z200 Microbial Turbidimeter is a benchtop laboratory instrument that measures the turbidity (density) of bacterial suspensions in McFarland (McF) units. It is intended for clinical and research microbiology laboratories that need to standardize bacterial suspensions to a defined concentration before downstream workflows such as organism identification and antimicrobial susceptibility testing. The TDR-Z200 is designed as a companion device to Mindray's TDR-series microbiology analysis systems, where a consistent inoculum density is required for reliable results.

How it works

The TDR-Z200 operates on the principle of turbidimetry: it passes light through a sample tube and measures how much is scattered or absorbed by suspended microbial cells, then reports the result on its built-in display as a McFarland value. An integrated LCD shows the date, time, measurement result, and unit of measurement, and an internal clock-linked memory stores recent test results for review.
