Classic Spectronic 21 spectrophotometer by Milton Roy. These are well-known, durable lab instruments commonly used for measuring absorbance and transmittance in chemistry, environmental, and biology applications.
Unit powers on and appears complete. From a working lab environment, but I do not have the setup or standards to fully test/calibrate, so selling as-is.
