Solvents of this Special Quality are carefully analysed to exceed or to meet the limit of UV absorbtion.

These Solvents of high quality standards are of much greater mechanical strength.

Solvent particles are much smaller than conventional liquid solvents. Columns are operated at a very high pressure to maintain high quality standards.

Solvents are filtered through 0.22 m filter.

All of our HPLC Solvents are packed under Nitrogen for its better Resistance and bottles are sealed with Teflon Liner to prevent contamination.
