Description

General description

20 Aluminium sheets 5 x 7.5 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.

Application

Aluminium HPTLC Silica gel 60 F₂₅₄ plates. Silica gel HPTLC plates size 5 x 7.5 cm, 20 sheets.
