Colonne cromatografiche
Le colonne cromatografiche separano le molecole all’interno delle miscele durante metodi a gas o liquido. Riempite con fasi stazionarie o resine, le opzioni preconfezionate riducono il tempo di preparazione richiesto. I pezzi verticali sono in grado di resistere a temperature estreme e fluttuazioni di pressione quando la fase mobile viene forzata attraverso il mezzo. Soddisfa le procedure di laboratorio preparative e analitiche con le colonne cromatografiche per separare componenti mobili dissimili in base a polarità, composizione e dimensione.
