HPTLC Silica gel F₂₅₄GLP

半岛bd体育手机客户端 说明

一般描述

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.
25 Glass plates 20 x 10 cm
