一般描述

25 Glassplates 20 x 20 cm
Precoated Kieselguhr or mixed Silica gel/Kieselguhr plates are only of small importance nowadays. Kieselguhr layers are used like cellulose layers for the TLC separation of polar and moderately polar substances. Polyamide, on the other hand , is used for the separation of flavonoids and other phenolic substances.
