High Performance Liquid Chromatography LB-33HPLC Catalog

High Performance Liquid Chromatography LB-33HPLC features a quaternary low-pressure constant flow pump with a 0.001 to 10.0 mL/min flow rate for accurate mobile phase delivery. It delivers a maximum operating pressure of 70 MPa (10,150 psi) to support high-performance chromatographic separations. The UV-Vis detector provides a 200 to 800 nm wavelength range with deuterium and tungsten lamps for sensitive detection. It also supports precise solvent composition control and 8-channel digital signal output for efficient data acquisition.
