Savillex microcolumns are used to perform ion-exchange sample preparation in geochemistry. These molded PFA microcolumns come in a variety of reservoir and capillary combinations. Threaded microcolumns can also be used with a closure for prevention of airborne contamination. PTFE frits (sold separately) are available for standard microcolumns. Savillex can also manufacture custom microcolumns. Contact Savillex with required reservoir size and capillary length specifications for pricing and availability.
