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.

Product Overview

The PFA-Coated Heating Rack is a critical performance-enhancing accessory for ultra-clean laboratories. While flat hot plates are versatile, they often suffer from inefficient heat transfer when used with round-bottom or thick-walled PFA vials. This specialized rack acts as a high-efficiency thermal bridge. By nesting the vials within precision-machined wells, it creates a "mini-dry block" environment on top of your existing hot plate. This ensures uniform digestion, prevents "cold spots" at the top of the sample, and protects the hot plate surface from accidental mechanical wear.

Product Synergy & Workflow

Optimized for the high-purity heating chain:

• Inert Hot Plates (Graphite/Aluminum): Designed to sit directly on the hot plate surface, converting a flat heater into a high-throughput digestion block.

• PFA Vials (15ml, 22ml, 30ml): The primary partners; the rack is designed to hold these vials securely during evaporation or acid digestion.

• PFA Reflux Covers: Can be used on the vials while in the rack to facilitate a fully closed, contamination-free digestion cycle.

Application Fields & Industries

• Trace Element Analysis: Ensuring identical heating conditions for all samples and blanks in ICP-MS preparation.

• Geochemistry: Accelerated dissolution of geological samples using concentrated HF/HNO₃ mixtures.

• Semiconductor Quality Control: Controlled evaporation of high-purity chemicals where temperature precision is critical.

• Environmental Testing: Large-batch processing of soil and water extracts for heavy metal screening.
