Description

General description

100 Glass plates 5 x 20 cm

Aluminiumoxide plates are used to analyze basic and neutral compounds at different pH levels. Depending on the pH range in question, professionals can choose between two kinds of aluminum oxide plates. Under aqueous conditions, basic aluminum oxide plates are best for separating basic compounds, while neutral plates are ideal for separating neutral compounds. Available with or without a fluorescence indicator, our TLC aluminum plates handle a wide variety of applications thanks to neutral and basic aluminum oxides with 60 Å and 150 Å pore sizes.

Application

Glass TLC plates, aluminum oxide coated with Flourescent indicator F254. The aluminum oxide TLC plate comes in a quantity of 100 size 5x20 cm for thin layer chromatography applications.
