Supplier: TECHNICAL QUARTZ SOLUTIONS

Fused silica tubes are made from natural quartz to ensure high quality and versatility

Supplier: Restek

These packaging materials can be used for easy scale-up to preparative chromatography or for packing the desired columns.

Supplier: Merck

Bei den Multiformat-Platten von Merck handelt es sich um vorgeritzte Glasplatten, die problemlos in kleinere Plattengrößen gebrochen werden können. Die Platten besitzen die gleiche Kieselgelbeschichtung wie die entsprechenden DC- oder HPTLC-Platten und liefern somit identische Chromatogramme.

Supplier: MACHEREY-NAGEL

Unmodified HPTLC silica layers available as glass plates with or without fluorescent indicator. The narrow fractionation of the silica particles features theoretical plate heights, which are one order of magnitude smaller than on standard silica layers. Thus, Nano-ADAMANT has the advantage of sharper separations, shorter developing times, and increased detection sensitivity with equal selectivity.

Supplier: Thermo Fisher Scientific

This TLC high purity grade silica gel with gypsum binder and fluorescent indicator is used for thin layer chromatography plate preparation.

Supplier: Thermo Orion

Orion™ AQUAfast™ Auto-Test Ampoule Reagents can be used with the Orion™ AQUAfast™ AQ4000 colorimeter to simplify sample preparation and tests.
