Laboratory and Equipment at the Institute of Geography

Coring and Survey Equipment

UWITEC piston corer 60 mm equipped with additional weights for “hammer action”. Freeze cores (up to 3 m long) are taken with Richard Niederreiter UWITEC, long piston cores in collaboration with Mike Sturm / Flavio Anselmetti EAWAG
Technicap PPS 4/3 is sequential sediment trap (12 bottles, 0.05 m^2)

Multisonde Hydrolab DS5X, DS5, and MS5 measuring the water column with sensors pressure/depth, T, O2, electric conductivity, pH, redox potential

 Echosounding with GPS Garmin GPSmap 178 Sounder

Core Lab and Sample Preparation

Cores are split using a core cutter.

Freeze dryer Christ Alpha 1-2 LD Subsamles are freeze-dried and dark stored.


Once the cores have been split and sampled, they are stored in the core lab and the cold room.



Specim Single Core Scanner VNIR (400 - 1000 nm) with ENVI software.

Environmental Scanning Electron Microscope (Zeiss EVO 40XVP) and image Analysis software (Scandium Version 5.0 Build 1200 by OLYMPUS SOFT IMAGING SOLUTIONS). Collaboration with GLOOR INSTRUMENTS AG. The SEM is also used for archaeological analysis, e.g. by ArcheoTex.

Magnetic susceptibility. MS 2 measurement device RS 232, MS 2E sensor. The equipment is portable.

A variety of microscopes including petrographic microscopy (Leica Wild M10, Leica DM LP) with digital camera and image analysis.
