The furnace runs almost daily, processing batches of samples at temperatures ranging from 500°C to 700°C. With the Hearth Plate for Barnstead International Type 1400 Furnaces, Barnstead PH48X1 installed, the first few runs were smooth and uneventful, which is exactly what you want in a lab setting. The temperature within the furnace seemed more consistent, and there were no unusual hot spots detected during thermal imaging.

Even with high-moisture samples causing increased steam and potential corrosion within the chamber, the PH48X1 hearth plate remained unaffected. It’s crucial to maintain cleanliness, but the plate proved resistant to staining and easy to wipe down after each batch. The previous plate showed signs of warping at higher temperatures, leading to uneven ashing, but this new plate held its shape perfectly, ensuring consistent results across all samples.

The initial surprise was how little the installation impacted our workflow. We didn’t have to recalibrate our heating protocols, and there were no hiccups in temperature control. It was a genuine drop-in replacement, delivering immediate benefits without any unexpected drawbacks.
