Savillex HPX-100 PFA-Coated High-Temperature Acid-Resistant Heating Plate

Overview

The Savillex HPX-100 is a high-performance, acid-resistant electric heating plate engineered for demanding sample preparation workflows in trace-metal analysis, geochemical digestion, semiconductor wafer processing, and high-purity material synthesis. Unlike conventional ceramic or stainless-steel hotplates, the HPX-100 employs a monolithic, ultra-pure graphite heating core—certified to semiconductor-grade purity standards—fully encapsulated in perfluoroalkoxy alkane (PFA), a fluoropolymer offering exceptional chemical inertness across concentrated mineral acids (including HF, HNO₃, HCl, and aqua regia), strong bases, and aggressive oxidants at elevated temperatures. This PFA overmolding eliminates crevices, seams, or exposed metal surfaces, preventing leaching of trace contaminants and ensuring compliance with ultra-trace analytical requirements (e.g., EPA Method 3050B, 3051A, 3052; ISO 17294-2; ASTM D5688). The unit operates via resistive heating within the graphite substrate, delivering stable thermal output with minimal thermal lag and no electromagnetic interference—critical for use alongside sensitive instrumentation such as ICP-MS or HR-ICP-OES.

Key Features

• Ultra-pure graphite core with full-surface PFA coating—resistant to HF, boiling HNO₃, and mixed-acid digestions up to 240 °C
• Integrated PTFE thermal guard ring surrounding the heating zone, minimizing edge heat loss and protecting lab personnel from accidental contact
• Digital PID temperature controller with real-time LED display, enabling precise setpoint adjustment in 1 °C increments and continuous monitoring
• Temperature uniformity of ±2 °C across the active heating area (292 mm × 212 mm) when stabilized at 150 °C—validated per ASTM E220
• Robust electrical architecture compliant with TÜV Rheinland and CE safety directives (EN 61000-6-3, EN 61000-6-4, EN 61326-1), including overtemperature cut-off, ground-fault protection, and double-insulated housing
• Low outgassing profile suitable for Class 100 cleanroom environments and semiconductor front-end fabrication support applications

Sample Compatibility & Compliance

The HPX-100 is explicitly validated for use with Savillex® PFA, TF-5000, and SCP Science digestion vessels, as well as other high-purity fluoropolymer labware. Its inert surface prevents catalytic decomposition of organic matrices and eliminates metal ion migration—essential for certified reference material (CRM) analysis and regulatory submissions under ISO/IEC 17025. The system meets functional requirements for GLP-compliant laboratories conducting USP , FDA 21 CFR Part 11–enabled workflows (when paired with Savillex’s optional data-logging interface), and environmental testing per EPA SW-846 Methods. No silicone, epoxy, or adhesive interfaces are used in construction—ensuring long-term stability under cyclic thermal stress.

Software & Data Management

While the HPX-100 operates as a standalone analog-controlled instrument, it supports optional RS-485 serial integration with Savillex’s LabControl Suite v3.2—a validated software platform enabling remote temperature logging, audit-trail generation, user access control, and electronic signature capture. All temperature events—including ramp profiles, hold durations, and fault triggers—are timestamped and stored with cryptographic hashing to satisfy 21 CFR Part 11 Subpart B record retention mandates. Raw data exports comply with ASTM E1382 and ISO/IEC 17025 clause 7.5.2 for measurement traceability.

Applications

• Open-vessel acid digestion of geological, biological, and environmental samples prior to ICP-MS quantification
• Controlled evaporation of high-purity solvents (e.g., sub-boiling HNO₃) in cleanroom-based trace-metal clean labs
• Pre-concentration of aqueous standards in certified calibration labs accredited to ISO/IEC 17025
• Thermal conditioning of PFA-lined reaction vessels during low-pressure hydrothermal synthesis
• Stabilization and drying of silicon wafers and photomask substrates in semiconductor R&D

FAQ

Is the HPX-100 compatible with hydrofluoric acid (HF) digestion protocols?

Yes—the entire heating surface, including edges and mounting hardware, is fully PFA-coated and rated for continuous exposure to ≥49% HF at temperatures up to 200 °C.
Does the unit include calibration documentation?

Each HPX-100 ships with a NIST-traceable factory calibration certificate covering temperature accuracy and uniformity at three points (100 °C, 150 °C, 200 °C), valid for 12 months.
Can multiple HPX-100 units be daisy-chained for synchronized operation?

Yes—via RS-485 Modbus RTU protocol, up to 32 units can be networked and controlled from a single host PC using LabControl Suite.
What maintenance is required?

No routine maintenance is needed; the PFA surface requires only deionized water wipe-down after use. Graphite core lifetime exceeds 10,000 operational hours under standard load conditions.
Is third-party validation support available for GMP audits?

Savillex provides IQ/OQ documentation templates, risk assessments (per ISO 14971), and on-site qualification services aligned with Annex 15 and ASTM E2500.
