The SpeedExtractor E-916 is your best solution for fast pressurized solvent extraction (PSE). Increase productivity by extracting up to six samples in parallel. Discover the concerted workflow of PSE with parallel evaporation using the MultivaporTM for unprecendeted speed and throughput.

Typical application: determination of extractables, additives and crosslinked share.

Extraction System B-811 / B-811 LSV

The Extraction System B-811 provides multiple extraction methods, including automated Soxhlet with high recovery rates and best precision.

Typical application: all extraction tasks to be done with classical Soxhlet as solvent extractables, additives or by-products from polymerisation process.

Multivapor™ P-6/12

The MultivaporTM P-6 / P-12 speeds up your sample evaporation for multiple samples. With its ease of use, the Multivapor is tailored to maximize efficiency. The collection vials of the SpeedExtractor E-914/E-916 are compatible and therefore no manual sample transfer is needed.

Typical application: evaporation to dryness for gravimetrical determination of extractables or cross-linked share.

NIR-Online Sensor

You need to control your processed tightly to reduce waste and optimize your manufacturing operation. Our industry-proven solutions for warehouse, laboratory as well as in-, on- and at-line production give you real-time control.

Typical application: determination of residual moisture and/or solvent; polymerisation end-point; raw material qualification, hydroxyl number measurement.

Melting Point M-560

Determination of melting point and melting range with high accuracy.

Typical application: determination of melting range of crystalline polymers.

Rotavapor® R-300

Convenient and efficient rotary evaporation from the market leader. The SpeedExtractor E-914 accommodates round bottom flask for solvent collection; the extracts can be evaporated directly with the rotavapor without manual sample transfer.
