Beschreibung

General description

25 Glass plates 20 x 20 cm,

These pre-scored glass plates fold into smaller formats with just one easy snap of the fingers.

Application

Glass TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 25 size 20x20 cm for thin layer chromatography applications.
