DIOXIN / PCB, PFAS ANALYSIS
D-EVA: Parallel and Fast Evaporation of Your Samples
The vacuum concentrator D-EVA allows unattended, parallel and rapid concentration of several samples with automatic stop at a defined volume between 30 and 150 µL for the dioxin fraction and approx. 300 µL for the PCB fraction.
The quantitative transfer into a GC vial is possible without time-consuming rinsing of the sample vessel.
For the EVAporation of PFAS the rotor can be equipped with the required Falcon Tubes™.

DETAILS AT A GLANCE
A cryotrap, collecting all evaporated solvents at minus 60°C, thus avoiding vapours in the laboratory - easy disposal.
- Reliably evaporate almost to dryness, to a final volume of 30 to 150 µL for the PCDD/F fraction or 300 to 500 µL for the PCB fraction.
- Technical design reliably prevents boiling distortion, cross-contamination in the headspace and adsorption of analytes on the glass wall.
- Supply of thermal energy via infrared lamps, after switching off the lamps no further heating or evaporation takes place.
Simple self-explanatory operation of the device.
The Brilliant Solution for the Concentration of Samples
When cleaning up PCB and dioxin samples, it is necessary to concentrate the samples to a very low volume for the subsequent analysis. Active evaporation beyond dryness should be urgently avoided to retain the analytes. With the D-EVA vacuum concentrator, LCTech, a specialist in automated sample clean-up, has developed a solution for the fast and parallel concentration of 1 to up to 53 samples.
D-EVA in the laboratory
Sample Concentration
The technology and design of the system ensure that any further active evaporation after the end of the process and cross-contamination are reliably prevented.
The sample is centrifuged at a moderate speed during the concentration process. This creates a centrifugal force that prevents boiling retardation. No cleaning steps are necessary during the process.
Centrifugation of the samples
No Solvent Vapours in the Laboratory Thanks to Cryotrap
Alongside easy-to-use software, D-EVA is supplied with a highly efficient cryotrap, which re-condenses and collects the solvent. This means that no vapours occur in the laboratory and the user can dispose of the solvents easily. In addition, D-EVA takes up little space in the laboratory as only one device is needed to process several samples in parallel. Various rotors are available for different containers.
