Accurate and Precise

The SER 158 provides reliable and accurate results improving extraction process compared to traditional Soxhlet method (five times faster). The determination of extractable matter is performed with a solid-liquid extraction process that removes soluble components from solids using a liquid solvent. The SER 158 guarantees excellent reproducibility and compliance of the results to the major standards. LED guidance for active positions helps to monitor and supervise the whole process.

Fully Scalable and Proven Performance

SER 158 configuration is fully scalable.
In addition to the first unit equipped with the new powerful ControlPad, your investment is protected by seamlessly allowing the increase of connected units according to the throughput requirements.
A single ControlPad is able to control up to 4 SER 158 independent with a maximum of 24 active positions processing up to 168 samples/day (or 42 samples/day/unit).

Easy User Interface and Smart Data Management

The SER 158 is equipped with a large 7 inches display extractable ControlPad with an intuitive User Interface for a powerful and smart data management and includes a multi-lingual support.
Integrated yet removable, the ControlPad can be connected with a balance for a completely new user experience.
Each extraction step is easy visualized on the ControlPad along with a great set of information and options. Results are immediately calculated and stored on the on-board memory.
