General description
25 Glass plates 10 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.
