The Cerex 48 Sample Concentrator Positive Pressure SPE Manifold provides a means to batch process solid phase extraction columns in the 48-position format. Using positive pressure to push liquid samples through spe columns is a more efficient process than using vacuum. Positive pressure provides more even flow and flow control of liquids going through a spe column.
Each of the 48 holes in the Processor manifold are restricted in order to maintain the manifold pressure even if all of the positions are not filled by columns. In addition there are valves located on top of the manifold that shut off individual rows of 12. With no column in place, there is approximately 0.75 +/- .05 scfh of flow through a hole at 25 psig.
The processor collection tube racks are optimally designed for 75mm or 125mm high collection tubes and a single rack for SPE elution and evaporation eliminates time consuming transfers and misplacement of samples.
