HCP621G-PMH DESCRIPTION
The HCP621G-PMH is a gastight, temperature-controlled probing stage capable of heating and cooling between -190°C and 600°C. Four (4) independent electrical probers are manually positioned onto the sample, which rests on a 38mm x 42mm silver thermal block. Electrical heating provides precision temperature control up to 600°C, while Instec's optional LN2-P system enables sample cooling via LN2 circulation down to -190°C.
The HCP621G-PMH gastight chamber supports a positive-pressure gas purge up to +0.5 bar for reactive/ Inert gasses or humidity control. The alternative HCP421V-PMH model comes with a vacuum-tight chamber, and is rated for a positive pressure +0.5 Bar gas purge, or a rough 9.9*10^-3 mBar evacuation for prevention of condensation or oxidation while heating/ cooling. The vacuum-tight version is strongly recommended for extended duration experiments at low temperatures, but has a reduced upper heating limit of 400ºC under vacuum.
The HCP621G-PMH is specially designed using non-ferromagnetic materials in the heating/ cooling core that will not interact with applied magnetic fields. The non-magnetic region extends in a 50mm radius from the center of the sample area, and is suitable for pole diameters of up to 100mm. The 26.5 mm thick chamber easily fits into a range of permanent or electromagnets without compromising electric field strength. Pair the HCP621G-PMH with Instec's M06T Manual Hall Effect Station to perform Hall effect measurements with simultaneous precision temperature control and atmospheric control. For applications that do not require Hall Effect Measurment, the HCP621G-PM or HCP421V-PM models are reccomended instead.
Upgrade to a -MP model to access advanced customization options such as additional electrical feedthroughs, triaxial/ SMA connector options, custom lids and much more.
