Biochrom Colorimeter, Ultrospec 35c, 440-680nm
A compact, portable, flexible colorimeter
· Measures the absorbance/transmission of liquid samples in either a cuvette or test tube at fixed wavelengths to determine molecular concentration.
· Ideal for the basic molecular quantification and analysis in Life Science, Chemistry and Physics.
· Perfect in the lab or for field-based work, in industry, environmental studies or remote locations where simple colorimetric testing is paramount.
Key features:
· Flexible analysis: Measures samples in absorbance and % Transmission modes as well as having simple kinetics functionality.
· Robust LED light source: User-selectable wavelengths: 450, 500, 520, 540, 600 and 640 nm.
· Touchscreen display: The instrument has a 4.3’’ color touchscreen for easy workflow.
· Instrument data output: Measurement data can be exported to a USB flash drive as comma-separated values (.csv).
Versatile and portable: The instrument has a small footprint allowing it to be operated as a handheld battery powered unit or connected to mains power on your benchtop. It is easy to clean and requires very minimal maintenance.
