Merck, 1055660001, TLC plates, Silica gel 60 F₂₅₄ GLP

General description
25 Glass plates 20 x 20 cm
These plates feature individual laser coding for GLP applications. Designed for GLP applications, the tops of each of these plates bear an item, batch, and individual plate number. As a result, lab professionals can easily record and archive every plate they use. Based on our proven silica found in TLC and HPTLC plates, these GLP plates deliver equally unsurpassed separation performance.
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.
