Graphite Inert hot plate 400*300mm

Product Overview

The Inert Graphite Hot Plate (PFA Coated) represents the pinnacle of sample heating technology for trace analysis. By leveraging the superior heat distribution of graphite, this hot plate eliminates "hot spots" that can lead to uneven digestion or sample bumping. The entire heating surface is shielded by a chemically bonded PFA coating, which prevents acid migration into the graphite core. This dual-material construction offers the perfect balance of thermal efficiency and chemical longevity, outperforming traditional ceramic or metal-surface plates in the most aggressive laboratory environments.

Product Synergy & Workflow

As the thermal engine of a high-purity laboratory, it integrates seamlessly with:

• PFA Vials & Jars: Perfect flat-surface contact ensures efficient heat transfer from the plate to the digestion vessels.

• PFA Digestion Racks: Can be placed on the graphite plate for parallel processing of large sample batches, ensuring identical heating conditions for all vials.

• PFA Cleaning Tanks: Placing a tank on the hot plate to warm cleaning acids significantly accelerates the decontamination process for labware.

• PFA/FEP Reagent Bottles: The PFA-coated surface allows for easy cleanup of accidental acid drips, maintaining a pristine workspace.

Application Fields & Industries

• Geochemistry & Mining: Ideal for long-term mineral digestion using hydrofluoric acid (HF).

• Environmental Analysis: High-throughput sample pretreatment for heavy metals in soil, sediment, and wastewater.

• Semiconductor Industry: Used for the evaporation and concentration of ultra-pure chemicals and wafer cleaning solutions.

• Food & Drug Safety: Acid digestion of complex matrices to provide high-quality samples for ICP-MS analysis.
