EVA IV Sample Concentrator

EVA IV Sample Concentrator

For Fully Automated Sample Preparation

The advantages of automation:
- Automated tranfer of the sample into sealed
GC or 16 mL vials
- Sample handling without supervision, e.g. over night
- Methods are saved matrix-oriented and can be reused on demand
- Reproducible results independent of user
- Fully automatic solvent exchange
- User protection due to usage of seals and retention of solvent vapours
- No laborious rinsing of rotators and their pistons and no carryover
- No suspect results caused by unintended concentration to dryness

Exact concentration of organic solvents - many applications 

With the EVA system up to 52 samples can be handled fully automatically in sequence. It reproducibly concentrates samples coming from a sample reservoir to an exactly defined end volume (1 or 5 mL) and afterwards precisely fills the concentrate into e.g. GC vials.

The sample is handled according to its sensitivity: With volatile compounds the concentration is done carefully, so the recovery rates are respectively high. In contrast, for samples without volatile compounds the maximum vacuum is used and operation time thus is reduced. If the solvent has to be exchanged, it can be done automatically at any time.

Due to its reliability, robustness, high reproducibility and repeatability the EVA IV is widely established in many laboratories for sample concentration.

The system can be directly controlled via device terminal or optionally via the especially developed VarioSoft software, making operation simple.
