Gravimetric Sorption Equipment
Laboratory system for the investigation of sorption processes in mesoporous materials. The amount of adsorbed material (e.g. water) in pores is measured by the high sensitive Satorius micro scale with 0,1 µg resolution.
Small-Angle-Scattering System NanoStar
Lab instrument for Small-Angle X-ray scattering experiments (Bruker AXS, Karlsruhe), with sealed-tube X-ray generator (Cu-radiation), cross-coupled multilayer mirrors (Göbel Mirrors) and 2D area detector (HiStar, Bruker AXS).
Contact Angle Device Krüss DSA100M
Drop shape analysis device used for dispensing pico liter droplets. Due to the need for creating droplets smaller than 1µl we purchased together with Joanneum Research this second drop shape analysis device from Krüss.
Equiped with a piezo driven dispenser and a microscope for drop visualization it is capable of measuring the contact angle of water droplets with a volume of only 100pl. The resulting small droplet in the µm size allows investigation of surface patterns and paper fibers and much more.
Contact Angle Device Krüss DSA100
Drop shape analysis device from Krüss, mainly used for free surface energy determination. The first of our two drop shape analysis devices. We use this machine mainly for determination of surface free energy of solids.
The system is equiped with an revolver that allows dispensing of four standard test liquids. In our case these are water, diiodmethane, ethylenglycol and 1-bromnaphtaline. Furthermore, the system is equiped with a heating chamber that also allows to create an intert gas atmosphere.
In two consecutive Proficiency Test (2007, 2008) organized by the ofi our lab has finished within the best 5 labs out of 19-25. within all subtest we alwas had the best possible performance of very good.
Atomic Force Microscope Asylum Research MFP-3D for polymers
This MFP 3D system has been aquired together with the department for Materials Science and testing of plastics (Ao. Prof. Dr. Wallner). It is mainly used for investigating polymers and biological materials. In comparison to the other MFP 3D it has possible to use a PolyHeater for varying the temperature up to 300 °C. Additionally it has an active anti-vibration table from Halcyonics (Micro 40). The system is shared with the collegues from the plastic engineering department.
Magnetic Force Microscope Asylum Research MFP-3D for MFM
This MFP 3D system is mainly used for investigating magnetic and biological materials. In comparison to the other MFP 3D it has possible to use a magnetic field up to 100mT.
Atomic Force Microscope Digital Instruments Multimode
Nanoscope III Multimode AFM from Digital Instruments is used for studying of various surfaces, among those are surfaces of semiconductors, metals, etc. It is well equipped with the set of cantilever holders, scanners and Q-modulator it can operate in few modes, such as: tunneling, contact mode AFM, tapping mode AFM, tapping mode in fluids, lateral force mode, conductive probe, electric force imaging and others.
UHV Omicron AFM/STM
UHV AFM/STM for C-AFM and in-situ investigation of organic thin films.
The system is based on the Omicron UHV AFM/STM. The old Solaris controller has been replaced by a modern custom build controller from Anfatec. The new controller now also allows to use all the dynamic modes more easily. Furthermore, the system is equipped with some limited thin film growth equipment. This includes a resistive evaporator for organic materials from Dr. Eberl, a quartz crystal balance, a home build electron gun heater and an ISIS3000 ion source for structuring and cleaning of samples.
