Unveiling the True Temperature: Say goodbye to the blind spot caused by discrepancies between displayed and sample temperatures, and achieve ultimate precision and control in your experiments.

In pursuits of ultra‑precise material synthesis, thermal analysis, or chemical research, a hidden variable is often overlooked: the discrepancy between the temperature displayed on the controller and the actual core temperature of the sample. This systematic bias, arising from thermal resistance, represents a critical bottleneck that undermines experimental reproducibility and data accuracy.

What is a hot-and-cold stage?

The temperature‑controlled stage enables simultaneous sample heating/cooling and transmission‑ or reflection‑mode optical observation. It is compatible with microscopes, inverted microscopes, infrared spectrometers, Raman spectrometers, X‑ray instruments, and more. Applications span polymers and liquid crystals, materials science, spectroscopy, biology, pharmaceuticals, geology, food science, freeze‑drying, X‑ray diffraction, and other fields.

The correct method for cleaning flux residues from the heating plate

The heating plate is a thermostatic device specifically designed for the heated pre‑treatment of various analytical samples. It features a microcrystalline glass worktop that offers excellent corrosion resistance, a smooth surface, and easy cleaning; its large heating area facilitates batch processing of multiple samples. Its modular design keeps the controller away from acid fumes, ensuring safety and ease of operation. A platinum resistance sensor provides precise temperature control, enabling rapid and uniform heating with a maximum temperature of up to 400°C. It is equipped with a large LCD display and includes a thermal warning indicator: if the surface temperature exceeds 50°C, the warning light turns red.
