DESCRIPTION
The HCP421V-PM is a vacuum-tight, temperature-controlled probing stage capable of heating and cooling between -190ºC and 400ºC. 4 independent electrical probers are manually positioned onto the sample, which rests on a 28mm x 30mm silver thermal block. Electrical heating provides precision temperature control up to 400ºC under vacuum or ambient conditions, while Instec's optional LN2-P system enables sample cooling via LN2 circulation down to -190ºC.
The HCP421V-PM vacuum-tight chamber is rated to 10*10^-3 mBar for prevention of condensation or oxidation while heating/ cooling. The chamber also supports a positive-pressure gas purge up to +0.5 Bar for reactive gasses or humidity control.
This miniature probing stage is ideal for performing electrical device or materials characterization, and can easily be used with optical instruments to add temperature control capabilities to almost any optical tool.
Upgrade to the HCP421V-PM+ model to access advanced customization options such as additional electrical feedthroughs, transmission apertures, triaxial/ SMA connector options, custom lids and much more.
