105567 TLC Gel silika 60/silikagel F₂₅₄ Aluminum TLC plates, Silica gel & Kieselguhr coated with Flourescent indicator F254. The Silica gel & Kieselguhr TLC plate comes in a quantity of 25 size 20x20 cm for thin layer chromatography
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, Silica gel & Kieselguhr coated with Flourescent indicator F254. The Silica gel & Kieselguhr TLC plate comes in a quantity of 25 size 20x20 cm for thin layer chromatography applications.Suhu penyimpanan : tidak ada batasan.
