Sample Holder Receiving Station – SHR 100 – 400
Together with the OmniVac SH Sample Holder series, the SHR 100 Sample Holder Receiving Station provides easy and versatile access to your samples. The pneumatically driven mechanics establish reliable contact for six electrical connections (e.g. type C thermocouple, heater, 2x Bias or type K thermocouple) as well as for the sapphire sphere equipped cooling finger. The maximum heating or sample current is 15 A. All electrical contacts, heating and cooling can be maintained continuously during sample positioning and rotation, which makes the SHR system unique. The sample transfer station is completely build up of non-magnetic components and can be mounted either with fixed room coordinates or for position alignment on a rotatable HPM XYZ manipulator.

Sample Holder – SH 100
The OmniVac SH 100 Sample Holder series provides a highly flexible mounting system for your samples which meets an outstanding range of desired experimental conditions due to their unique design. The six electrical contacts are equipped with a thermocouple, a resistive heater and two free pins for e.g. biasing or resistance measurements. The whole sample plate can be efficiently cooled down by LN2 (down to 88 K) or LHe.
Heating allows for reaching temperatures up to 2300 K. Different heating methods may be applied as e.g. direct or indirect heating, electron bombardment etc. Many non-standard sample holders are available, e.g. quartz balance, Faraday cup, charge neutralization, optical measurements in transmission etc. Modifications to meet your particular needs can easily be realized.
