Flexible, Precise, Modular


There are two different EVAporation techniques, which can be applied individually or combined. These are only selected in the software – no changes need to be made to the hardware!

  • Parametrisable vacuum via chemically inert vacuum pump including controlled heating and rotation of the EVAporation chamber
  • Nitrogen blowdown (for sensitive analytes and final volumes < 0.5 mL)

Precise Final Volume

Samples can be concentrated precisely to a final volume between 0.2 mL and 5.0 mL fully automatically. The process is controlled using software and sensors. Methods with different final volumes can be easily mixed in one sequence, without any mechanical adjustment. Particularly valuable for certified laboratories: The EVAporation chamber can be calibrated fully automatically.


Fully Automated Process

Double-walled needle with two independent lines. For the outer line, spray holes are arranged 360° around the needle. Ideal for thorough all-round cleaning of a vessel.

  • Spraying solvent into a vial or into the vacuum chamber for rinsing and cleaning.
  • Avoidance of overpressure when dispensing into a septum-sealed vial, by releasing the displaced air via second needle channel.
  • Sharp tip for piercing a septum. The design reliably prevents the needle from being blocked by part of the septum.

Chemically inert vacuum pump with intelligent control.

Conically shaped EVAporation chamber for fast, low-loss and targeted evaporation:

  • Double-walled, filled with temperature-controlled liquid.
  • Condenser for solvent recovery.

Overfill sensors for safe monitoring of the EVAporation process.

Additional parameterisable, electric heating zone for optimum EVAporation in the small volume range.

Fluid level sensor for the final volume, which you can set individually for each sample via software 0.2 mL to 5 mL.

Flexibility in all Areas

Drawing choice of evaporation principle | © LCTech GmbH
  • Similar to the rotary evaporator principle with controlled heating of the sample via a closed water cycle and application of a parametrisable vacuum
  • Nitrogen blowdown
  • Combination of both principles in one method

  • Liquid/liquid solvent exchange
  • Solvent exchange to dryness and with resuspension in solvent of choice
  • Connection for 3 solvents or upgradeable to 6 or 15 solvents
Choice of output and final volumes | © LCTech GmbH
  • Sample volumes up to 350 mL can be concentrated in one process. To do this, the sample is aspirated in batches into the evaporator chamber using a vacuum. FREESYLE recognises when the entire sample has reached the EVAporation chamber.
  • Freely definable final volume between 5.0 mL and 0.2 mL, which can be set individually for each sample via software-controlled sensors. This means that samples with different final volumes can also be mixed within one sample sequence.
  • The result is a precisely filled or aliquoted concentrate, in freely selectable containers (e.g. closed GC vials).

  • Rinsing of the EVAporation chamber during the process, especially shortly before the selected final volume is reached
  • Rinsing of the EVAporation chamber and all parts that have come into contact with the sample once the process is complete

With the double-walled needle from the FREESTYLE system, the analytes are rinsed down from the walls of the EVAporation chamber with a solvent of choice, while the EVAporation chamber rotates so that no analytes remain on the glass walls.

This increases the precision and repeatability of your results enormously.

The EVAporation chamber is calibrated automatically with the simple click of a mouse in the software. This is particularly appreciated by certified laboratories:

  • EVAporation method setup: Process steps can be added easily with a mouse click. Values are set by sliding bars
  • Combination of SPE and EVAporation method in what is known as a “FLEX” method. This can also be saved and easily retrieved again later

Commonly Chosen Combinations

Pesticides, PAHs, Dioxins and PCBs

FREESTYLE BASIC, combined with the GPC and EVAporation module for clean-up with the aid of gel permeation chromatography. In this case, the GPC main fraction can be transferred into the EVAporation chamber online, where it is concentrated.

Environmental Samples

FREESTYLE BASIC, combined with the SPE and EVAporation module to automate SPE processes. This allows eluates from the SPE to be eluted online into the chamber of the EVAporation module and concentrated.

Water Samples

FREESTYLE XANA combined with the EVAporation module for EVAporation following the SPE process for water samples from 1 L to 10 L and filling of the processed sample into GC vials, ready for the subsequent analysis.

Online Injection

FREESTYLE BASIC, combined with the SPE and/or GPC module, EVAporation and HPLC Direct Injection module for direct transfer of the perfectly processed sample into an HPLC.
