SR100 – interchangable sample platforms for the FC100

SR100 Sample Carriers for FC100

One of the most challenging aspects of any uniaxial strain measurement is sample mounting. This process is made even more difficult if electrical connections must be made to the sample. The SR100 sample carriers simplify this process by allowing multiple samples to be mounted on multiple sample carriers that can be rapidly exchanged when required.


Accessory Overview

  • Allows rapid sample exchange between pre-prepared samples
  • Suitable for use with FC100
  • Flexure guided to reduce effect of misalignments on strain homogeneity
  • Compatible with the WP101 wiring platform: exchange with contacts intact.
  • Mounted samples can be processed (heat/plasma/etch) detached from device


Applications and Use

Make more efficient use of instrument time

Every research group wants to be getting the best use out of their cryostat (and other instrumentation). Preventing wasted time saves research budget and increases the speed at which data can be collected. Time becomes even more precious at a user facility, such as magnet or a beamline, when a whole PhD can rest on just a few days data collection. Razorbills range of SR sample carriers mean that a broken sample does not lead to disaster, merely a few minutes inconvenience.

Experiment with tricky-to-mount samples

The SR sample carriers can withstand high temperature epoxy cures, plasma surface treatments and aggressive acid cleaning processes. Consequently, they are suitable for use with high-temperature cure epoxies that may allow reliable bonding to samples that were previously difficult to mount or attach contacts to.

Retain samples for future experiments

At the end of a strain experiment, with conventional sample mounting, it is impossible to remove the sample while keeping the electrical contacts intact, and usually it is very difficult not to break the sample completely. SR sample carriers can be removed from the stress/strain cell with the sample and electrical connections intact. This means that the samples can be filed away and kept in case more measurements are required later.


The sample is mounted on the sample platform as normal, the one exception being there are no sample mounting screws. Instead the sample resting in epoxy surrounded by a horseshoe-shaped spacer capped with a cover foil. If desired, high temperature epoxies can be used because the sample platform is much more resilient to high temperature than the stress/strain devices themselves.

If the intended measurement that requires contacts near the sample (for example an electrical transport measurement of a magnetic susceptibility measurement) then a WP100 wiring platform can be added to the device.

Electrical transport measurements can be challenging because of the requirement to make electrical contacts to the sample either before or after the sample is mounted. A SR sample platform can be incredibly helpful, because it allows many samples to be prepared on many sample platforms in advance of a measurement. If a failure occurs at low temperature, for example a sample unexpectedly breaking or a wire detaching, then one prepared sample can be exchanged for another in a matter of minutes.
