Analytical HPLC-A7835

Description :

Analytical HPLC-A7835 system is equipped with a flow rate range of 0.0001 to 10 ml per minute. Integrated with a single and dual wavelength UV-Vis detector with a range of 190 to 800 nm that analyzes sample’s absorption at different wavelengths and a high pressure pump providing continuous consistent flow. Built in column heater provides reproducible retention time.
