Eurosil Bioselect 300-5 C18A with precolumn, Column 150 x 4 mm

Ultra pure, spherical wide pore HPLC phase based on silica gel

Unpolar, monomeric C18 (Octadecyl) modification, endcapped, with 7 % carbon content (hydrophilic endcapping).


Separation mechanism: Hydrophobic and polar interaction

Key features

Eurosil Bioselect 300 C18A has been specifically developed for the determination and purification of peptides, proteins, and oligonucleotides up to MW approx. 5,000 Da. The optimized manufacturing process guarantees excellent batch–to-batch reproducibility. The Eurosil Bioselect sorbent is the first choice for Biochromatography with silica material.

Recommended application areas

Hydrophilic and polar biomolecules, peptides, very polar biomolecules separated with 100 % aqueous eluents.
