In-situ environments
Advanced solutions for demanding sample environments and in-situ testing
We can provide a wide range of solutions for various types of in-situ tests, as well as accommodate samples with specific demands for the sample environment. The in-situ sample environments are available for use with both the 3D x-ray microscope (Zeiss XRM520) and the RX Solutions EasyTom150 micro x-ray tomograph. If a unique sample environment that is not listed here is required for your experiments, please contact the lab as more in-situ devices are available for use.

General-purpose in-situ compression / tension device
- Adaptable to compression, tension, triaxial (with pressure cell) and adhesion testing.
- Force and displacement measurement plus control through LabView.
- Load levels form <100 N up to >1.5 kN
- Typical sample sizes are 1-3 mm, but can be different dimensions.
- Can be fitted with grips for different sample types:
- Flat samples (e.g., paperboard).
- Cylindrical dog bone samples (e.g., metal).
- Compression platens.
- Indentation platens.
- Confining tubes for 1D uniaxial compression of powders.
- Pressure confinement cell for triaxial compression (e.g., for geomechanical testing).
- Possibility for heating.
In-situ deep-drawing / forming device
- Designed for dry forming of paperboard sheets, but could be used for other materials.
- Ca. 25 mm diameter circular samples.
- Different forms could be envisaged.
In-situ pressure-plate humidity cell
- Pressure-based humidity cell for reaching high levels of relative humidity.
- Sample size in the order of 1-5 mm.
- Works with compressed gases (including air or nitrogen) at about 100 kPa.
In-situ freezer
- Peltier-based freezer connected to cryo-unit.
- Temperatures down to about -20 °C possible.
- Sample sizes of up to 10 mm have been tested, larger samples could be possible.
- One-sided cooling (from base), but with adapted sample holder can be more isotropic.
- Application of vacuum around sample is under development.
In-situ triaxial compression device for rocks
- Up to about 35 MPa confining pressure.
- 25 mm diameter x 50 mm long cylindrical samples.
- Force, displacement and pressure measurement plus control through LabView.
- Controllable pore pressure as well as permeability testing with pressure or flow-rate boundary conditions.
- Axial (deviatoric) loading with either an external mechanical frame with in-built rotation or with a pressure driven cylinder (not shown in photo).
Small 6 N in-situ compression / tension device
- Load levels from up to 6 N with a piezo-motor.
- Large displacement range.
- Adaptable to compression, tension or peeling (adhesion).
- Force and displacement measurement plus control through LabView.
- Typical uses have been peel testing and single fibre tensile testing.
