Stability 300 BS-C23

Wide-Pore Stable-Bond C23 Column for Robust Biomolecule Separations

Stability 300 BS-C23 from Dr. Maisch HPLC GmbH is a high-purity silica-based wide-pore HPLC column with a 300 Å pore size and a stable-bond C23 bonded phase. The extra-long alkyl chains provide very strong hydrophobic retention and unique selectivity compared to conventional C18 or C8 phases, making it particularly suitable for the analysis of proteins, peptides, and other large biomolecules.

The stable-bond technology ensures outstanding resistance to extreme pH conditions, aggressive eluents, and high temperatures, enabling long lifetime and high reproducibility even in demanding proteomics and biopharmaceutical applications.

Stability 300 BS-C23 columns from Dr. Maisch HPLC GmbH combine wide-pore accessibility, strong hydrophobic retention, and superior robustness – the ideal choice for challenging biomolecule separations in HPLC.

Key Features:

  • Fully porous, ultra-pure silica with 300 Å pore size

  • Stable-bond C23 bonded phase for maximum hydrophobic retention

  • Optimized for large biomolecule analysis (proteins, peptides, antibodies)

  • Excellent chemical stability under harsh conditions

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH

Typical Applications:

  • Protein and peptide separations in proteomics and biopharma

  • Biopharmaceutical QC and characterization of therapeutic proteins

  • Preparative purification of highly hydrophobic biomolecules

  • Long-gradient methods for complex biological samples
