Please be aware, we are currently investigating the 1 mL eVol syringe calibration process. We have recently identified that the fractional dispensing feature is not meeting our precision and accuracy specifications. Our investigation is ongoing and we will notify you with any further updates in due course. If you would like to speak to one of our customer service team regarding the issue, please contact us at info@trajanscimed.com.

Every One an Expert

eVol® xr digital analytical syringe is the coupling of two precision devices: a digitally controlled electronic drive and an XCHANGE® enabled analytical syringe.

eVol xr syringes are easily and quickly changed allowing them to be dedicated to individual liquids or methods to prevent possible cross-contamination of reagents.

MEPS® is Micro Extraction by Packed Sorbent, the miniaturization of conventional SPE packed bed devices from milliliter bed volumes to microliter volumes.The MEPS approach to sample preparation is suitable for reversed phases, normal phases, mixed mode or ion exchange chemistries.

The MEPS Barrel Insert and Needle (BIN) assembly contains the stationary phase, and is built into the syringe needle.

Features and benefits

eVol MEPS BINs are compatible for use with eVol Syringes.

The eVol xr custom programming function enables MEPS (micro SPE) to be semi-automated, reducing errors, and improving reproducibility.

Recommended applications

SPE method development, and/ or proofing before transition to fully automated platforms. Processing small sample batches, or urgent samples.

Product specifications

MEPS BINs are available for use with eVol, with C2, C8, C18, Amino-Propyl Silane phases, for LC and GC applications.

MEPS BINs can be used with 50 µL, 100 µL and 500 µL eVol MEPS syringes.
