Multiple Dividing Wall Column

The first pilot-scale multiple dividing wall column. The column allows the separation of a quaternary mixture into four pure components. For this purpose, a simplified configuration with two dividing walls was selected, whereby the dividing walls are not physically designed but the corresponding column segments are run in parallel in this sections. During the design phase, great importance was attached to flexible operation. The plant is 9.6 m high, has a total of about 220 theoretical stages and is equipped with a vacuum system.


Formalbs Fuse 1 and Sift

The SLS printer Formalbs Fuse 1 allows high precision printing in PA12 with a build volume of 165 mm x 165 mm x 300 mm. A workbench (Formlabs Sift) and a sandblaster are available for finishing the printed components.

Rectification Test Rig

This self-constructed unit is fully automized and allows the determination of pressure drop, and seperation efficiency (HTU/HETP) for our 3D printed columns and packings. It can be used for a wide range of column diameters as well as gas and liquid loads.

Test Rig for Liquid Distribution Measurements

This test facility allows us to measure the liquid distribution in additively manufactured packings. A wide range of possible diameter can be investigated. Different liquid distributors and liquid collectors are available fo this task.

CINC extractor V02 / CS50

This extraction centrifuge can be used for liquid-liquid extractions in non-reactive and reactive systems. The RPM ranges from 0 to 6000 (= 0 to 1000 g). The feed stream can be varied between 0,01 and 1 L/min.

30L Brewery Kit

The 30 L brewery kit from "Klarstein" allows the controlled mashing, lautering and hop boiling in one device and is therefore well suited for smaller test runs. This plant is mainly used by the student brewing working group "Kesselgold" for pilot trials before the brewing process is transferred to the large plant.

Lab Reactor IKA LR 1000 control

This fully automated lab reactor is an all-rounder used for batch reactions, extraction and for crystallization. Maximum working temperature: 125°C. Maximum vacuum: 25 mbar. An IKA Ultra-Turrax T25 digital is part of the unit. Software: Labworldsoft.

Lab Reactor Vorwerk Thermomix

Not only good for cooking but most likely the cheapest lab reactor in the world :-) The temperature controlled Thermomix is used for the preparation of emulsions and suspensions.

Gas Chromatograph Shimadzu Nexis GC-2030

GC equiped with autosampler (120 vials) and FID detector. Software: LabSolutions

UV/VIS Photospectrometer Thermo Scientific Genesys 50

The GENESYS 50 is a dual beam UV-Vis spectrophotometer (190 nm - 1100 nm wavelength) in a single-cell configuration for precise chemical measurements.

Contact Angle Measurement Dataphysics OCA15 EC

This device allows the computer aided determination of static and dynamic contact angles. Equiped with a thermostat chamber for controlled measurement environment.

Refractometer Krüss DR6300-T

The temperature controlled refractometer measures the refractive index in a range between 1.32000 to 1.70000 with an accuracy of +/- 0.00002 and the %Brix in a range of 0 to 0.95 with an accuracy of +/- 0.02.

Karl-Fischer Titrator

The volumetric KF-Titrator V10S from Metler Toledo allows water analysis from 100 ppm to 100 wt.-%.

Viskosimeter IKA RotaVisc

The level of measurement accuracy of this rotational viscometer for both Newtonian and non-Newtonian fluids is +/- 1 % of the measuring range. The reproducibility is +/- 0.2 %. Viscosity measuring range: 1 - 6,000,000 mPas.

VLE Determination Device
