Product Overview

Description


BANGKAI Column Chromatography Silica Gel 60


 


Properties:


It is white odorless powder insoluble in water, acids and organic solvents.


It features uniform pore distribution and high compressive strength.


Because of the high surface hydroxyl group activity, it can achieve rapid separation and purification


under high and medium pressures.


Its chemical molecular formular is sio2.


 


 


Application:


1. SPE and FLASH fillers.


2. Used in biochemical research and the production of thin-layer chromatography analysis plates.


3. Used for the preparation of chromatographic column filler material, suitable for rapid separation.


 


Specification:


               class:reagent grade
