Automated Liquid-Liquid Extraction (LLE) Systems

The VERSA automated Liquid Liquid Extraction (LLE) system, also known as an automated solvent extractor or liquid-liquid extractor, offers the most flexibility and throughput among all other liquid handlers, by utilizing our innovative modules:

  • Conductive Liquid Level Sensing – detects phase boundary and ensures precision, reproducibility, and minimal dead volume
  • ReagentDrop Bulk Dispensing Module – dispenses solvents (including organic solvents) and reagents without using tips, prevents dripping of volatile solvents
  • On-deck Tube/Plate Shaker – for mixing and online reconstitution
  • Heater Assisted Nitrogen Dryer – enables a complete walk-away solution for liquid-liquid extractions
  • Versatile Labware – adaptors available for virtually any shape and size (microcentrifuge tubes, test tubes, vials, etc.)

The VERSA Automated Solvent Extraction systems are highly scalable for different throughput and budget requirements. These instruments can automate a number of applications, including extractions of drugs-of-abuse and other metabolites of interest from bodily fluids, as well as biomolecules of interest from biological matrices (such as lipids and proteins). Please contact us for additional information and applications.

Frequently Asked Questions

VERSA Automated Liquid-Liquid Extraction (LLE) workstations offer the most flexibility and throughput among all liquid handlers, due to the inclusion of our innovative modules. VERSA workstations are very flexible and open, allowing compatibility with almost all kits, reagents, and labwares available in the market.

To minimize solvent evaporation, the included ReagentDrop channels dispense bulk reagents directly from sealed compartments (pressurized-bottle) located off the deck. These sealed compartments reduce reagent evaporation and exposure resulting from highly volatile reagents such as methanol. The VERSA Automated Liquid-Liquid Extraction workstation is armed with an exhaust to deal with volatile reagents. Additionally, as the ReagentDrop dispenses organic solutions without using tips, dispensing can be done quickly for large and small volumes, and tip usage is decreased.

Yes, the nitrogen dryer block can be used for solvent evaporation and sample concentration, and it can be transferred into a drying position above the test tubes/vials by the plate gripper. The combination of shaker-heater, nitrogen dryer, and gripper enables complete walk-away solution for any LLE protocols.

VERSA is equipped with a powerful shaker for vortex mixing of organic solvents and aqueous samples, and the timing and speed (RPM) of the shaking process can be optimized for your application, as well as changed on demand within the included software.

Yes, VERSA LLE workstation features Conductive Liquid Level Sensing for detecting the phase boundary between organic and aqueous solvents, ensuring precision and reproducibility in your LLE procedures. Alternatively, you have the option to define aspirate heights (Z position) to remove one liquid/phase from the other.
