The Knauer Prep LC Premier LC system is a very flexible preparative chromatography system to optimise your purification and synthesis work. The modular system can be perfectly adapted to your need, whatever kind of application you want to use. Usually it's been used with special edition of Dataapex Clarity (Clarity Prep), perfect for preparative work in a modern lab. To give you a small overview of the potential of the Prep LC Premier, we created 5 Prep bundles. These packages are the first step to build your individualised Prep LC Premier system.

Rack, code 22, holds quantity of 44, 18×150 mm tubes (25 ml), for use with FC204

Supplier: Avantor

These are used in low pressure preparative chromatography. The mesh specifications ensure there is no excess of fines in the product which can affect flow rates and separation performance.

Supplier: MERCK PRODUCTION CHEMICALS

Composed of magnesium and silicon oxides in the approximate ratio of 85:15. This is a polar phase used for the chromatography of compounds such as steroids and alkaloids. This activity can be controlled by the activation temperature used.

Supplier: MERCK PRODUCTION CHEMICALS

Micro-crystalline cellulose is a hydrophilic polysaccharide packing material preferred for the raw separation of amino acids and related compounds. Cellulose is also used for the gentle purification of bio-molecules. Because of the organic nature of cellulose, it can only be used in pre-swollen state and under gentle or hydrostatic pressure.

Supplier: Cytiva

HiLoad™ Superdex™ prep grade are prepacked XK columns designed for pre-parative gel filtration. Superdex™ prep grade is a composite matrix of dextran and highly cross-linked agarose. The steep selectivity of dextran, and the high chemical and physical stability of agarose, enable high resolution separations. The chromatography media combines high mechanical strength with high hydrophilicity, allowing high flow rates and minimal non specific interactions.

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.

Geduran® Si 60, 40 - 63 µm

Supplier: Cytiva

HiLoad™ 16/600 Superose™ 6 prep grade (pg) is a prepacked size exclusion chromatography (SEC) column for high-resolution purification of large biomolecules and protein complexes. The column is an excellent choice for purification of sample volumes up to 5 ml.

Supplier: MERCK PRODUCTION CHEMICALS

Selection of Merck's standardised and modified silica gels that are available in many granulations and supplied from one single source, dedicated to chromatography. Standardised silica gels are widely used in separation processes to purify valuable compounds in ton quantities. Modified silica on the other hand is used in separation problems, which cannot be adequately solved using unmodified silica.
