| Description | HPTLC Silica gel F₂₅₄ |
| Overview | 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. |
