Reid Vapor Pressure Tester Model 12210 (4-Position Bath)

Overview

The Reid Vapor Pressure Tester Model 12210 is a precision-engineered, 4-position water bath system designed for the standardized determination of Reid Vapor Pressure (RVP) of volatile petroleum products—including motor gasoline, aviation fuels, naphthas, and liquefied petroleum gas (LPG)—in strict accordance with ASTM D323 (for liquid petroleum products) and ASTM D1267 (for LPG). RVP is a critical specification governing fuel volatility, vapor lock resistance, evaporative emissions control, and safe handling during storage and transportation. This instrument implements the classical Reid method: a fixed-volume, fixed-ratio (1:4 vapor-to-liquid) test assembly is immersed in a precisely controlled water bath at 37.8°C (100°F), and equilibrium vapor pressure is measured after stabilization. The Model 12210’s dual-wall stainless steel bath architecture, PID-controlled thermal regulation, and ±0.1°C temperature stability ensure high reproducibility across repeated tests—essential for regulatory compliance, quality assurance, and refinery process control.

Key Features

• Four independent test positions enabling parallel analysis of up to four samples per cycle—significantly improving laboratory throughput without compromising measurement integrity.
• PID-controlled digital temperature regulation with ±0.1°C stability over the full operating range (ambient to 100°C), verified by integrated dual-LED display showing both setpoint and real-time bath temperature.
• Robust dual-wall stainless steel construction with insulated chamber walls, minimizing thermal drift and enhancing energy efficiency during extended operation.
• Integrated over-temperature protection circuitry preventing thermal excursion beyond safe operational limits.
• Depth-adjustable sample holder fixtures ensuring consistent immersion depth of vapor pressure cans (as required by ASTM D323 Section 7.2 and D1267 Section 6.2).
• Optional RS232 serial interface for external data logging or integration into LIMS environments; optional ramp-mode heating profile for controlled thermal equilibration.
• Compliance-ready design supporting audit trails when paired with validated software systems—facilitating adherence to GLP and GMP documentation requirements.

Sample Compatibility & Compliance

The Model 12210 accommodates standard ASTM-compliant vapor pressure cans (e.g., 12065, 12071, 12072) in either single- or double-valve configurations. It supports both liquid-phase testing (ASTM D323, ISO 3007, IP 69) and pressurized LPG testing (ASTM D1267, ISO 4256, IP 161), as well as DIN 51616 and DIN 51754 methodologies. All hardware interfaces—including pressure gauge adapters, connecting tubing, and vent valves—are dimensionally and material-certified to meet specification tolerances defined in the referenced standards. The 51.9 L bath capacity ensures stable thermal mass for uninterrupted multi-hour testing cycles under ambient load variations.

Software & Data Management

While the base unit operates as a standalone analog/digital benchtop instrument, optional firmware upgrades enable time-stamped temperature logging and pressure event capture via RS232. When integrated with compliant third-party laboratory software (e.g., LabWare LIMS or Thermo Fisher SampleManager), the system supports 21 CFR Part 11–compliant electronic records—including user authentication, audit trail generation, and immutable result archiving. Calibration history, maintenance logs, and operator annotations can be associated directly with individual test runs to satisfy internal QA protocols and external regulatory inspections.

Applications

• Quality control laboratories in refineries and blending terminals verifying RVP compliance prior to product release.
• Environmental testing facilities assessing evaporative emissions potential under EPA Tier 3 and EU Stage V fuel regulations.
• Research and development labs evaluating formulation effects on volatility behavior across reformulated gasoline blends.
• Contract testing organizations performing accredited ASTM D323/D1267 analyses for third-party certification (e.g., ISO/IEC 17025).
• Government metrology institutes conducting interlaboratory comparison studies and reference material validation.

FAQ

What standards does the Model 12210 fully support?
ASTM D323, ASTM D1267, ISO 3007, ISO 4256, IP 69, IP 161, DIN 51616, and DIN 51754.
Can the instrument be used for both gasoline and LPG testing?
Yes—when equipped with appropriate sample cans (12072 for LPG) and pressure gauges (e.g., 12206 or 12207), it meets all procedural and hardware requirements for both ASTM methods.
Is the temperature bath calibrated traceable to NIST standards?
The unit includes provisions for external calibration verification using NIST-traceable RTDs or thermometers; full calibration certificates are available upon request with optional service contracts.
What electrical specifications are required for operation?
230 V AC, 50 Hz, single-phase supply; nominal power draw ≤1.8 kW.
Does the system include pressure measurement instrumentation?
No—the base configuration includes only the thermostatted bath; pressure gauges (models 12201–12207) and sample cans (12065, 12071, 12072) are ordered separately to match application-specific pressure ranges and sample types.
