Descripción

Descripción general

50 Glass plates 20 x 10 cm

HPTLC plates deliver fast and quantitative analysis of complex samples for manual or automated use. Our HPTLC silica plates work three times faster than conventional TLC plates – and they are more sensitive. The particle sizes range in HPTLC is between 4-8 µm, which creates a smoother surface and a higher separation power than TLC plates.
