Hai cercato: Colonne cromatografiche
Chromatography columns separate molecules within mixtures during gas or liquid chromatography. Filled with stationary phase compositions or chemical compounds, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual solvent polarity, composition, and size. The right chromatography control system allows to automate the delivery of cleaning, sanitizing and conditioning buffers to the packed column, and can enable to cycle the chromatography column several times during the batch, requiring smaller columns and subsequent lower capital investment.

Colonne HPLC per cromatografia preparativa Chromolith®
Supplier: Merck
Le fasi stazionarie in silice monolitica Chromolith® Prep sono costituite da silice ultrapura, che derivano le loro speciali proprietà da una struttura bimodale della silice. Questa struttura è caratteristica di una nuova tecnologia 'Sol-Gel' ed è costituita da macropori e mesopori. I mesopori, con un diametro medio di 12 nm, formano la struttura porosa fine all'interno della colonna e crea un'area superficiale molto ampia su cui si verifica l'assorbimento dei composti.
