Zeochem Silica Gel – Bulk Materials for Chromatography

Zeochem is a Swiss-based manufacturer of high-quality silica gels and chromatography materials, known for precision, reliability, and consistent performance across laboratory and industrial applications. They offer a comprehensive portfolio of bulk materials designed for demanding chromatographic separations.

The product families ZEOPrep® (irregular shape), ZEOSphere® (spherical shape), and ZEOBeads® (spheroidal shape) provide reliable performance, excellent reproducibility and flexible surface chemistry to meet a wide range of separation needs from research to large-scale production.

All ZEOCHEM bulk materials are available with a variety of surface chemistries (C18, C8, C4, Amino, SAX) to suit different separation mechanisms.

Find the right product family using the Zeochem Chromatographic Silica Selection Guide. You can find the guide and more useful information in the ZEOCHEM Chromatography Gels Brochure (PDF).

Advantages of ZEOCHEM product families

ZEOPrep® – engineered for preparative and process-scale chromatography. They combine mechanical stability with consistent particle morphology, enabling efficient separations and high loading capacities.
ZEOSphere® – feature highly uniform spherical particles with optimized pore structures. These materials are ideal for analytical and semi-preparative applications where precision and reproducibility are critical.
ZEOBeads® – offer versatile silica-based solutions with tailored particle sizes and pore distributions. They are suitable for a broad spectrum of chromatographic techniques, from research to industrial-scale purification.

Surface modifications of ZEOCHEM bulk materials

All ZEOCHEM bulk materials are available with a variety of surface chemistries to suit different separation mechanisms:

Silica – Unmodified silica for normal-phase chromatography and polar compound separations.
C18 (ODS) – Octadecyl functionalization for reversed-phase applications, offering strong hydrophobic interactions and excellent retention of non-polar analytes.
C8 (ODS) – Medium hydrophobicity phase, ideal for faster separations and moderately non-polar compounds.
C4 – Lower hydrophobicity phase, particularly suitable for proteins and large biomolecules where reduced retention is required.
Amino – Polar functional group providing weak anion-exchange properties and suitability for normal-phase and HILIC applications.

Choose Zeochem silica gel for efficient, precise, and flexible chromatography solutions tailored to your separation needs.
