ExtraVac® Vacuum manifolds

We recommend using pressure equipment (positive or negative) taking care not to allow the solvents to "fall" by gravity for maximum reproducibility.
There are several ways of carrying out solid phase extraction using ExtraBond®.
- For a small number of samples use a syringe and an adapter to ""push"" the solvents through the column by positive pressure using the adapters that are listed on this page. See Figure 1. See the adapters listed above in section ExtraBond accessories.
- Or, you can use the negative pressure provided by a vacuum source. See Figure 2
- When the number of samples is high and you want to achieve better reproducibility more rapidly, vacuum manifolds are the best choice. See Figure 3.
