Product Accessories

This page details the accessories available for the CS100 series and FC100 series cryogenic stress/strain cells. The accessories described include the power supply necessary to power the cell, the wiring platform for attaching the wires to the sample as well as the various sample mounting plates for mounting the sample horizontally or on-edge to be compatible with transmission-mode probes. A full modification of a quantum design PPMS probe for strain measurements is also offered.

MP240: High Isolation Multiplexer

  • Double pole, quad throw fully shielded coaxial multiplexer  designed  for  use  in  high  impedance  measurement systems.
  • Ideal for use with devices such as the UC200 that contain more than one capacitive sensor, or in cases where more than one stress or strain cell is used simultaneously.
  • Controlled by USB or by a digital input.  The digital input is compatible with Andeen-Hagerling capacitance bridges.

Sample Plates

  • Semi-disposable sample plates and spacers for mounting samples to the strain cell
  • Commercially pure titanium - high strength and thermally matched to the stress or strain cell
  • Compatible with the CS100 and FC100 family of stress/strain cells
  • Versions designed so that the sample can be mounted horizontally for transmission-mode measurements also available
  • Sample plates and spacers available in packs of twenty.

CS1X0_FLXSMPLT: Sample plate with flexures living a 200um slot for small samples

CS1X0_WIDEANplts: This plate raise the sample up to be flush with the top of the bridge and allow the sample to be the highest point in the cell and allow
360 hemisphere sample access.


WP100 Wiring Platform

  • Wiring platform allows tiny electrical contacts to be made more easily to samples for electrical transport measurements
  • Positions four contact pads within a few millimetres of the sample to make forming gold contacts to the sample easier.
  • Compatible with the CS1X0 and FC100 family of stress/strain cells
  • 4x header pin connector for integration with cryostat electronics

Strain cell stands and mounting table

  • When mounting a sample in the cell or when forming contacts to the sample it is often convenient to have a purpose built optical bench to make the fine manipulations easier.
  • Each type of strain cell (FC100 and CS series) has a stand so that they can be stood upright
  • These stands can be fitted into a central hole in an optical table.
  • If required, a translation stage can be screwed to the table to allow operations that cannot be conducted by hand.
  • The tapped holes in the table are typically provided in metric sizes, but can be made to imperial measurements, if requested.


PPMS probe conversion kit

  • A kit that provides the vacuum feed-throughs, cabling and wiring plates necessary to convert a quantum design PPMS to use our strain cells.
  • Easy to follow step-by-step instructions
  • Low cost accessory to help you modify your cryostat and get started as quickly as possible.

Attocube compatibility

Sometimes it is necessary to move a stress or strain cell around inside a cryostat, for example for optics alignment or to bring the sample into range of a scanning probe. To do this it is necessary to use a cryogenic nanopositioner, and one of the most commonly used types is that manufactured by Attocube. To make it easier for a customer to incorporate a Razorbill CS100 into their set-up, we can now provide a bracket to fix a CS100 to the top of an Attocube ANPx101 positioner. Likewise, we offer a custom FC100 cell, with a reduced weight to make it compatible with an ANPx101 positioner with a baseplate that can be fixed to the existing screw holes in the Attocube positioner.

 Right: An FC100 with the lightweight modification reduces its weight below 80g to allow it to be moved with an Attocube positioner. Its base plate will mate with an Attocube positioner.


PPMS Strain Probe

For our latest offering, we have teamed up with Quantum Design to offer a Razorbill Instruments version of an official QD multi-function probe. This probe will be compatible with any Quantum design PPMS and have all the required cabling, connectors and vacuum feedthroughs to enable immediate strain measurements at cryogenic temperature with minimal of customer set-up required.

  • Modified version of an official Quantum DesignP450 Multi-function Probe (MFP) for strain measurements.
  • Have a PPMS probe that you can reserve exclusively for stress/strain measurements.
  • No need to modify your existing PPMS or design a custom yoke.
  • Vacuum feedthrough and appropriate cabling already installed.
  • Ensure the strained sample is located precisely in the magnet centre.
