Launch new products Alternative Agilent inlet and outlet valves

New products developed by Chromasir, the replacement of Agilent check valve, is about to be launched. As an indispensable part in HPLC instrument, check valve contributes to a more precise experiment analysis. Chromasir's check valve is made of high-quality materials, with excellent durability and stability. Besides, our check valve is produced by adopting the cutting-edge manufacturing technology and precision production process, which have outstanding detail and precise dimension control. All of those achieve a distinguished and reliable performance.

All the check valves are manufactured in accordance with Chromasir's highest levels of quality and have been tested in HPLC (high performance liquid chromatography) instruments, to make sure they will have a great performance to work with the rest of the system. They are totally compatible with Agilent's liquid chromatographs. Our products struggle to increase customers' analytical, instrument, and laboratory efficiency to the greatest degree. A variety of check valves offered by us enable to meet the diverse needs of experiments and analysts in the fields of chemistry, pharmacy, biochemistry and environmental science. Chromasir's check valve is able to satisfy Agilent’s LC use requirements. What's more, to purchase our products will greatly reduce the experiment costs and delivery time.
