Efficient Sample Delivery and Analysis – The CS 1521 HPLC System is engineered for precision and productivity, offering ultra-reliable sample delivery and quantitative accuracy across all analytical workflows. Its advanced autosampler ensures exceptional injection repeatability with multiple injection modes, guaranteeing accurate and reproducible results. Designed for flexibility, it supports various sample tray configurations (2×54 or 2×96 well plates) and includes an optional refrigerated sample chamber to preserve sample integrity during long runs. The system’s innovative inner and outer needle design minimizes sample residue to less than 0.0025%, ensuring clean, contamination-free injections. A user-friendly graphical interface simplifies sequence setup and tray selection, allowing smooth operation even in high-throughput environments. Combining precision engineering with intelligent automation, the CS 1521 HPLC delivers efficient, reliable, and high-quality analytical performance for laboratories demanding accuracy and speed in every sample analysis.
