Puritas BIO eximius 300Å C18

 

Overview

The 21st century is often considered as the era of “protein science”. Peptide and protein research is quickly maturing to be the major driving force for new kinds of pharmaceutical ingredients. For both, the research and the big scale of peptide and protein manufacturing spherical silica must be tailor made, fine tuned. The new line up of PURITASTM BIO EXIMIUS is designed to serve these needs, featuring extended acidic and alkalic resistance and high loadability combined with exceptional durability.

The improved high density bonding and full end capping makes it very suitable to general use and to separate or purify high molecular weight compounds, especially proteins. Because of the significant improvement in durability and acidic, alkalic resistance it can be used for extended period of time in acidic mobile phase condition and rinsed for recovery with NaOH containing buffer.

Key Features

  • Recommended for highly hydrophobic bulky molecules
  • Novel chemical bonding assures stability under severe alkalic and acidic conditions
  • Designed for protein purification
  • 30nm pore size, narrow distribution range
  • Totally spherical particles made of ultra high purity silica gel
  • Featuring extended acidic and alkalic resistance and high durabilit
