This complete stand-alone unit, BCVS10DC, is designed for first dimension capillary/tube gel electrophoresis, and comprises omniPAGE tank and lid, tube gel module, tubes and blanking ports. Units are interchangeable with omniPAGE slab gel and electroblotting modules. The Tube Gel Module itself includes a rapid release gasket for easy tube extraction. Focusing can be accomplished in as little as three hours. Disposable capillary tubes are included in addition to 2-D combs and spacers which are colour coded according to thickness for easy identification. Each of these techniques benefits from rapid set up cooling packs which provide enhanced resolution even during high intensity 2-D electrophoresis.
