Buck Scientific 235ATS Atomic Absorption Spectrophotometer

Buck Scientific 235ATS Atomic Absorption Spectrophotometer MSE Supplies is an authorized distributor of Buck Scientific instruments. Buy Buck Scientific products from MSE Supplies at the best value. The Buck Scientific 235ATS Atomic Absorption Spectrophotometer is designed for reliable trace metal analysis with high sensitivity, automated operation, and strong safety control. It features a high-energy optical design, in-line D2 background correction, automated wavelength and slit selection, push-button ignition, and a 10-inch color touchscreen for simple operation. The 235ATS includes Deuterium Background Correction to improve accuracy by reducing nonspecific background interference. Its optimized nebulizer-burner system supports stable sample introduction and improved sensitivity, even with challenging sample matrices such as samples with high dissolved solids or higher viscosity.
