The VERSA automated Liquid-Liquid Extraction (LLE) system, also known as an automated solvent extractor, offers the most flexibility and throughput among all other liquid handlers utilizing our innovative modules.
- Conductive Liquid Level Sensing – detects phase boundary and ensures precision, reproducibility and minimal dead volume.
- Stainless Steel Pipette Option – ensures compatibility with organic solvents.
- ReagentDrop Bulk Dispensing Module – dispenses organic solutions and other solvents without using tips, prevents dripping of volatile solvents
- On-deck Tube/Plate Shaker – up to 2500 RPM for online phase separation and reconstitution
- Nitrogen Dryer and Gripper – enables a complete walk-away solution for most LLE protocols.
The VERSA automated Solvent Extraction systems are compatible with various commercial labware and are highly scalable for different throughput and budget requirements.

Frequently Asked Questions
VERSA Automated Liquid-Liquid Extraction (LLE) workstations offer the most flexibility and throughput among all liquid handlers by utilizing our innovative modules. They are very flexible and open systems and compatible with almost all the kits, reagents and labware in the market.
To minimize evaporation, ReagentDrop channels can 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. VERSA automated Liquid-Liquid Extraction workstation is armed with exhaust provision for volatile reagents and as the ReagentDrop dispenses organic solutions without using tips, therefore dispensing will be quite fast and safe.
Yes, the nitrogen dryer block can be used for solvent evaporation and sample concentration, it can be transferred by plate gripper on the top of vials/tubes. 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 varied to optimize for your application.
Yes, VERSA Automated Liquid-Liquid Extraction (LLE) workstation features Conductive Liquid Level Sensing for detecting phase boundary that ensures precision and reproducibility. Alternatively, you have the option to define aspirate heights (Z position) to remove one liquid/phase from one another.
