Why Choose Empore™ Cartridges?
Combining Empore™ membrane technology with innovative cartridge design
Minimal Elution Volumes
Small bed volume design allows elution with as little as 100-200 µL for 1mL cartridges, eliminating evaporation steps and reducing total solvent usage. Perfect for LC-MS/MS analysis.
Prefilter Protection
Graded density polypropylene prefilter with multiple layers prevents clogging from biological samples, ensuring consistent flow rates and extending membrane life.
Versatile Compatibility
Standard luer design fits all common SPE manifolds and automated systems. Compatible with centrifugation, vacuum, and positive pressure processing methods.
Superior Reproducibility
Densely packed Empore™ membrane eliminates channeling effects, providing consistent extraction efficiency and reducing method development time.
