Options and accessories
Basic Experimental Insert
Supplied as standard, the basic experimental insert has a 6 mm
line-of-sight (LOS) access to the inner vacuum chamber (IVC).

Versa Experimental Insert
Our most versatile experimental insert with four custom
configurable wiring ports is specifically designed for easy
installation on KelvinoxMX. Choose between a range of wiring
options including twisted pairs, flexible coaxes or semi-rigid
coaxes to suit your signal requirements.

Rotator Insert
Mechanical rotator with 15 x 15 mm sample space allows for
260 degree polar rotation in high magnetic fields. The rotatorassembly below the mixing chamber is demountable to makespace for a cold finger when a fixed sample position is preferred.
The drive rod from room temperature is retractable to break thethermal connection to the mixing chamber after rotating thesample. The insert comes with a 12 twisted pair loom, two flexible
coaxes and two semi-rigid coaxes to suit a wide range of both
DC and RF experiments. Automated stepper motor control using
MercuryiTC.

Low Eddy Current Sample Holder
Our low eddy current sample holder with optimised geometry
minimises both sample temperatures during a field sweep andquench forces acting on the refrigerator during a magnet quench.

High MagneticFields

Unconventional
SuperconductivityElectrical Transport
Measurements- Compatible with our wet Integra magnet systems- Top-loading of the sample directly into the 3He/4He mixing chamber ensures good sample thermalisation, highstability of the thermal environment and guarantee of operation in high magnetic field- Unique design which can be used with a range of sample probes such as a mechanical rotator or high frequency
coaxial lines- No need to remove the mixture during sample change, giving quicker experiment turnaround times- Non-metallic sample environment: ideal for experiments such as solid state NMR, where removing metallic
material surrounding the pickup coil resonant circuit is key to accurate measurements- Delivered with a gas handling system, which enables automatic operation of a dilution refrigerator usingsophisticated software and virtual instrument drivers for LabVIEW.

Service Support Options
Sustainable Solutions
All Kelvinox inserts are compatible with the IntegraAC re-condensing
liquid helium cryostat. This product has been developed to significantly
reduce the consumption of liquid helium by re-condensing helium gas
evaporated within the system, which would otherwise be vented from thecryostat, decreasing the frequency of helium refills. Cryogenic systems
can be kept cold continuously, even when in standby mode, leading togreater freedom to schedule experimental time.
