DPX stands for Disposable Pipette EXtraction. It
is a patented solid-phase extraction (SPE) device that is unique from
all other SPE devices. DPX uses pipette tips that incorporate loosely
contained sorbent material that is mixed with the sample solution. This
unique mixing provides numerous advantages:
• No conditioning steps are necessary
• Minimal elution solvent volumes
• Rapid extraction times (less than 3 minutes/sample)
• High extraction efficiencies
• Easy to perform extractions
What does this all mean?
• Lower costs
• Higher throughput
• Environmentally friendly
• Minimal training required |

This video shows a rapid "cleanup" method using a DPX-WAX (weak anion exchange sorbent) tip. An acetonitrile solution of protein precipitated whole blood is rapidly processed in 60 seconds by aspirating the solution into the DPX-WAX tip, mixing the solution with the sorbent by aspirating air, and then dispensing the "clean" solution back into the tube. Note the comparison of with and without "cleanup" at the end of the video.
