LiChroprep® is a proven, highly successful packing material providing fast, effective and reproducible separations.

Supplier: MERCK PRODUCTION CHEMICALS

The aluminium oxide crystal structure comprises octahedrally and tetrahedrally coordinated aluminium coupled by oxygen atoms. The aluminium oxide surface is covered by free hydroxyl groups. There are different acidic and basic centers (Broenstedt acid, Lewis acid and Lewis basic centers) that result in anion and cation exchange properties. Aluminium oxide exhibits a higher pH-stability than silica gel, especially in the alkaline range. Aluminium oxide occurs in various crystal modifications resulting in different pore diameters.

Lysozyme lysates harvested from cultures of Micrococcus lysodeikticus were attached to sepharose and used for affinity chromatography to isolate various bacteriolytic enzymes and it has also been used in a study to investigate the encapsulation of protein drugs in microparticles.

Supplier: DR MAISCH

Semipräparatives und präparatives, sphärisches Kieselgelmaterial ermöglicht die Aufreinigung von Rohmaterialien von mg- bis zu kg-Mengen, je nach ID und Länge der Säule. Sphärische Materialien sind leicht in die Säulen zu packen.

Supplier: MERCK PRODUCTION CHEMICALS

Merck bietet für die Präparative Chromatographie standardisierte und modifizierte Kieselgele in mehreren Korngrößen aus einer Hand an. Standardisierte Kieselgele werden bei Trennverfahren verwendet, um wertvolle Bestandteile in Tonnenmengen aufzureinigen. Modifizierte Kieselgele werden dagegen bei komplizierten Trennverfahren eingesetzt, die mit Hilfe nicht modifizierter Kieselgele nicht zufriedenstellend durchgeführt werden können.

Geduran® Si 60, 40 - 63 µm

Supplier: MP Biomedicals

Silica is highly porous and has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. It is used as a suspending and thickening agent in pharmaceuticals. It is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes.
