Puritas BIO 300Å C-18

 

Overview

PURITAS BIO C18 phases are bonded with octadecyl groups and are fully end capped. They are recommended for larger molecules such as proteins with higher hydrophobicity and bulky molecules which are too difficult for separations. PURITAS BIO C18 phases are available in particle sizes of 5, 10 and 15 microns for both analytical as well as preparative applications.

Key Features

  • Recommended for highly hydrophobic bulky molecules
  • Most versatile wide pore reversed phase with high coverage and exhaustive end capping
  • Enhanced Mechanical stability
  • Exceptional Batch-to-batch reproducibility
  • Suitable for scale up and packing with dynamic axial compression columns under very high pressure
