HPLC Solvents from Agilent
All pictures shown are for illustration purpose only. Actual product may vary.
Agilent InfinityLab HPLC gradient grade solvents have been developed for optimum performance with Agilent LC instruments and applications. All solvents are manufactured with the lowest levels of impurities, and are pre-filtered through a 0.2 µm filter to protect your system from contaminants and clogging. Benefits include reduced troubleshooting and instrument downtime caused by impure solvents. Agilent HPLC solvents are easy to use, and offer excellent lot-to-lot reproducibility, ensuring consistent results.
Agilent InfinityLab HPLC solvents are shipped in 2.5 L high quality amber borosilicate glass bottles to preserve solvent integrity. Batch specific certificates of analysis are also available to meet GLP specific requirements.
Agilent offers HPLC gradient grade acetonitrile, methanol and water solvents, which are widely used in reversed phase HPLC applications.
