Grant Bio McFarland DEN-1 Densitometer

This listing is for a Grant Bio McFarland DEN-1 Densitometer. The unit is in full working condition and is ready for immediate release. The DEN-1 is a compact benchtop turbidity/densitometer instrument manufactured by Grant Bio (part of Grant Instruments). It is designed primarily for life-science and microbiology applications — for example, measuring the turbidity of cell suspensions (bacterial, yeast) or other particulate suspensions. Typical uses include: Determining cell concentration in fermentation or culture processes; Assessing microbial susceptibility (via turbidity changes); Identifying microorganisms in test systems; Measuring optical density / turbidity at a fixed wavelength for dyes or suspensions.
