OD/F device

Measuring Optical Density (OD) is a central element in microbiological work and synthetic biology in general. Often the qeustion is, how many cells are in a suspension. The OD can give you a hint.

Commercial OD meters cost several hundred dollars (OD meter), and can limit the spread of synthetic biology. Especially for BioHack-Spaces, DIY laboratories and schools we wanted to develop an alternative.

With our OD/F device we want to enable many to people for good, precise and cheap science.

Especially for the Interlab Study also fluorescence has been of importance. Here the correlation between OD and fluorescence should be measured. Since the taks of measuring OD and fluorescence are often performed at the same time, we want to present a device that can measure both with easy changes. Finally we can tell you, how much fluorescence there is per cells.
