Popis

General description

15 Glass plates 20 x 20 cm

PLC plates allow users to separate samples that vary greatly in size – from grams down to milligrams. Available with or without a fluorescence indicator, PLC plates has 1 mm thickness. They also use our same proven silica-binder technology as in analytical TLC plates. To isolate the substance by extraction, users can simply scrape the spot from the layer.

Analysis Note

Chromatographic testings:
A) Cholesterin test
