The MIXXOR Concept (seven easy steps)
1. Introduce sample and extraction solvent into reservoir A (Fig. 1)
2. Insert mixer-separator piston B into reservoir A, tighten cap S.
3. Pump four or more times to mix (Fig. 2)
4. Pull mixer-separator up slightly above liquid level and secure with holder spacer H. Loosen cap.
5. After separation, slide down the mixer-separator to transfer the upper phase into collection chamber E.
6. Adjust lower phase to top of axial channel C. (Fig. 1 and 3) Use fine adjustment on holder-spacer to secure setting.
7. Top phase can now be decanted safely, while lower phase stays in the axial chamber.
