105568 TLC Kieselguhr F₂₅₄ Aluminum TLC plates, Kieselguhr coated with flourescent indicator F254. The Kieselguhr TLC plate comes in a quantity of 25 size 20x20 cm for thin layer chromatography applications.
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.Aluminum TLC plates, Kieselguhr coated with flourescent indicator F254.
