The SPE-12G PTFE column processors are specially designed PTFE vacuum chambers that allow 12 samples to be run simultaneously. This offers the flexibility of processing SPE devices of different heights, diameters, or formats during the same experiment. It includes a borosilicate glass vacuum chamber, a white coloured polyamide lid including 12 Luer PTFE connectors, plugs (12×) for lid, a PE gasket, 12 Luer PP stopcocks and a PTFE sample collection rack set.
