Description

General description

25 Glass plates 20 x 10 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 HPTLC Silica gel F₂₅₄ GLP plates. Silica gel HPTLC plates size 20 x 10 cm, 25 sheets.
