DESCRIPTION
The HCP621G gastight plate is designed for applications where both thermal and atmospheric control is critical. Using a silver heating and cooling block, this plate provides a wide temperature range with great thermal uniformity for samples around 20mm or smaller. The sealable gastight chamber supports inert gas purge to eliminate oxidation, aid in humidity studies, or conserve expensive reaction gasses. Additionally, up to 4 optional electric feedthrough leads are available for sample connection and probing.
The HCP621G is perfect for adding precision temperature control to existing instruments such as Raman spectrometers. Optical windows are field replacable, and can easily be replaced to optimize performance for any optical wavelength.
Upgrade to the HCP621G+ customizable model to enable customizations such as adding transmission apertures (Changes model to HCS621G), vertical mounting capabilities, electrical feedthroughs, custom sample holders and much more!
For cooling between 25ºC and -60ºC, inert gas purge is effective at preventing condensation. Below -60ºC, inert gas purge becomes less effective, and evacuation is highly reccomended as an alternative, especially for long-duration experiments. The HCP421V is nearly identical to the HCP621G, but has a smaller total temperature range (-190ºC to 400ºC), and is designed to support evacuation into the medium-vacuum range of 1*10^-2 mBar to 1*10^-3 mbar.

TEMPERATURE UNIFORMITY EXAMPLE
In this video, we heat an Instec HCP621G from room temperature to 180C. The HCP621G has a hexagonal thermal plate which is approximately 30mm diameter in size. The Instec HCP621G and HCP421V thermal plates share the same hexogonal heater core. Instec rates most stages to a uniformity of 2% across the surface area and a stability to within 0.05C.
This video was taken using an IR imaging camera. A specially made imaging plate made of stainless steel was painted black to increase the IR emissivity and thus image quality. Thermal paste was used between the imaging plate and the heating plate. Some degree of non-uniformity is expected due to this setup and thus the Instec heating plate will have higher performance across the silver surface of the heating plate.
