Bench-top Spectrophotometer CM-5

An innovative Benchtop Spectrophotometer with user friendly features and a large onboard display. The CM-5 is a benchtop spectro with a top facing port meaning easy changes for solid samples and samples in petri dishes. It can also measure the color of liquid and transparent samples.
