Solid Phase Extraction System

N/A save time and simplify the disk method for oil and grease (EPA Method 1664), the StepSaver Solid Phase Extraction is constructed of borosilicate glass with a stainless steel filter screen. The collection vessel is located outside the filter flask or manifold, and uses a vacuum bridge to connect it to the vacuum source. A luer adapter is located in the solvent collection arm that allows the use of an inline Na2SO4 and can be directly evaporated to obtain the weight of the extracted oil and grease. The system is designed for use with 47mm solid phase extraction disks from 3M. A 90mm version is also available for other SPE applications requiring a larger filter. A two-way, 120 Teflon stopcock allows the analyst to choose the direction of filtrate flow. This design prevents accidental sample loss as the stopcock cannot be opened to both channels at the same time. The 40/35 ground glass joint on the bottom of the apparatus allows attachment to a filter manifold or filtration flask.
