Overview
The Spectra Invent HX-FPP1210 Cloud Point and Pour Point Analyzer is a dual-bath, microprocessor-controlled instrument engineered for precise, repeatable determination of cloud point (CP) and pour point (PP) in petroleum products and related hydrocarbon-based fluids. It operates on the principle of controlled cooling under standardized thermal ramping protocols, enabling automated observation of phase transition onset—specifically, the temperature at which wax crystals first become visible (cloud point) and the lowest temperature at which the sample retains fluidity under gravity (pour point). Designed in compliance with ASTM D2500 (cloud point), ASTM D97 (pour point), ISO 3015, ISO 3016, and Chinese national standards GB/T 510 and GB/T 3535, the HX-FPP1210 supports quality assurance workflows in refineries, lubricant formulation labs, fuel testing centers, and third-party certification facilities.
Key Features
- Dual independent refrigeration baths—each individually programmable—allow simultaneous or staggered CP and PP determinations on up to four samples (two per bath), improving lab throughput without cross-temperature interference.
- Patented cascade compressor refrigeration system combined with auxiliary air-cooling achieves rapid, energy-efficient cooling from ambient to −68 °C in ≤90 minutes, minimizing standby time between test cycles.
- High-stability PT100 platinum resistance thermometers integrated into each bath provide real-time feedback for closed-loop thermal regulation, ensuring ±0.5 °C control accuracy across the full −70 °C to +30 °C operating range.
- 0.1 °C digital display resolution enables precise visual verification of crystallization onset and flow cessation; all temperature readings are traceable to NIST-traceable calibration references.
- Ergonomic vertical chassis design minimizes footprint while facilitating benchtop mobility; reinforced housing and vibration-dampened bath mounts ensure mechanical stability during extended low-temperature operation.
- No external coolant or cryogenic consumables required—ethanol bath medium (>95% purity, ~2.5 kg per unit) provides uniform heat transfer and long-term chemical compatibility with paraffinic and naphthenic base oils.
Sample Compatibility & Compliance
The HX-FPP1210 accommodates standard ASTM/ISO glass test jars (e.g., ASTM D97 cylindrical tubes, 40 mm × 300 mm) and is validated for use with diesel fuels, jet fuels (Jet A-1, JP-8), lubricating oils, biodiesel blends (B5–B20), crude assay fractions, and synthetic hydrocarbon fluids. All operational sequences adhere strictly to the procedural requirements of GB/T 510 (petroleum products—determination of pour point), GB/T 3535 (petroleum products—determination of cloud point), and their international equivalents. Instrument firmware enforces mandatory hold times, ramp rates, and visual assessment intervals as defined in method clauses, supporting audit readiness for GLP and ISO/IEC 17025-accredited laboratories.
Software & Data Management
The analyzer operates via an embedded LCD interface with non-volatile memory storing up to 200 test records—including date/time stamps, operator ID, sample ID, final CP/PP values, intermediate temperature logs, and pass/fail status against specification limits. Data export is supported via USB 2.0 to CSV-compatible spreadsheets for integration into LIMS environments. While no PC-dependent software suite is bundled, the device generates timestamped, immutable result files that satisfy basic FDA 21 CFR Part 11 requirements for electronic records when paired with institutional SOPs governing user access control and audit trail retention.
Applications
- Quality release testing of middle distillates prior to pipeline shipment or marine bunkering.
- Formulation screening of cold-flow improvers (CFIs) and wax inhibitors in lubricant R&D.
- Batch-to-batch consistency monitoring in refinery blending operations.
- Contract laboratory services for API RP 14E, MIL-DTL-83133, and DEF STAN 91-87 compliance reporting.
- Educational use in petroleum engineering curricula for hands-on demonstration of phase behavior thermodynamics.
FAQ
What standards does the HX-FPP1210 comply with?
It is fully aligned with GB/T 510, GB/T 3535, ASTM D97, ASTM D2500, ISO 3015, and ISO 3016 for cloud and pour point measurement.
Can both cloud point and pour point be measured simultaneously?
Yes—the dual-bath architecture allows independent temperature programming: one bath can be set for cloud point ramping while the other maintains the static low-temperature soak required for pour point evaluation.
Is calibration verification supported?
The unit includes built-in calibration check mode using certified reference standards (e.g., NIST SRM 1484); users may perform daily verification per internal QA protocols.
What maintenance is required for long-term reliability?
Annual inspection of refrigerant charge, condenser coil cleaning, ethanol bath purity verification, and PT100 sensor drift check are recommended—no routine oil changes or compressor servicing needed due to sealed-system design.
Does it support networked data transfer or remote monitoring?
No Ethernet or Wi-Fi capability is integrated; data retrieval is limited to USB mass storage export, consistent with secure standalone instrumentation design principles for regulated environments.
