Dispersive Pipette XTRaction technology introduces the benefits of solid phase extraction into a revolutionary, easy-to-use pipette tip. This device is unique from fixed-bed resin formats because sorbent material is loosely contained within a tip.
XTRactions are fast! Depending on the application, our customers typically find that extraction time is significantly reduced when compared to traditional SPE. XTR tips are designed to work seamlessly on robotic liquid handlers, unlike conventional SPE.
The disperser helps to perturb the sample solution and loose sorbent during aspirate and dispense steps. This mixing provides a highly efficient interaction of the sorbent and sample solution resulting in ideal analyte recoveries and reduced matrix effects. You can seamlessly integrate XTR tips with any workflow or method.

Easy Sample Cleanup
Mix sample via aspirate and dispense steps
- No vacuum manifold
- Unparalleled ease of use
- Low cost, automated solution
- Custom method development
Bind - Wash - Elute
- Rapid extraction times
- Higher analyte recoveries
- Sorbent chemistry customization
While “dilute and shoot” methods are often perceived as “inexpensive” and “rapid”, our customers frequently tell us that they have had to purchase high-end ultra-sensitive instrumentation in order to achieve the desired analytical outcomes. By placing strategic emphasis on sample preparation (i.e. “the front end”), significantly higher costs associated with more expensive LC-MS/MS instrumentation may be unnecessary.
A customized product for your application
XTR tips are manufactured to order per custom specifications. Tips can hold 1 – 100 mg of sorbent depending on the tip format.
You can choose your chemistry to meet any unique selectivity for the diverse range of analytes.
- HybridSPE® – Phospholipid removal
- Mixed Mode – combine chemistries in custom amounts ex. WAX/RP
- DPX +SALLE – add Salt for a novel cleanup mechanism ex. WAX-S, RP-S
Whether you are in the early stages of method development with a new application or seeking to enhance current throughput, DPX offers a solution!
We’ve designed a workflow graphic to demonstrate the utility of DPX technology for sample preparation and purification for a variety of matrices and applications.
