Reliable High-Temperature Flash Point Testing with the Cleveland Open Cup Flash Point Tester DFp-303

Ensure safety and compliance in the testing of lubricants, bitumen, waxes, and high-flash petroleum products with the Cleveland Open Cup Flash Point Tester DFp-303—a precision-engineered, semi-automatic instrument designed to meet ASTM D92, ISO 2592, IP 36, and GB/T 3536 standards. Ideal for refineries, asphalt plants, and industrial lubricant labs, the DFp-303 delivers accurate, repeatable open-cup flash point results for materials with flash points above 79°C (175°F).

Engineered for Standardized, Safe, and Efficient Testing

The DFp-303 Cleveland Open Cup Flash Point Tester features a robust electric heating system with precise temperature control and a motorized test flame applicator that automatically sweeps across the sample surface at defined intervals. Its open-cup design allows vapors to mix freely with air—simulating real-world conditions for high-viscosity or high-flash materials like residual fuels, greases, and polymer-modified bitumen.

Compliant with ASTM D92 & ISO 2592 – Validated method for lubricants, asphalt, and heavy fuels.
Wide Temperature Range: Ambient to 400°C – Suitable for high-flash materials with ±1°C control accuracy.
Motorized Flame Arm with Adjustable Height – Ensures consistent flame application per standard requirements.
Digital Temperature Controller & Safety Cutoff – Prevents overheating; includes over-temperature protection.
Stainless Steel Test Cup & Shielded Burner – Durable, easy to clean, and minimizes external air interference.
Ergonomic Design with Fume Hood Compatibility – Safe operation in ventilated environments; optional exhaust adapter available.

Trusted for Heavy-Duty Material Safety Assessment

Unlike closed-cup methods, the Cleveland Open Cup (COC) test reflects the behavior of materials under open-air heating—critical for assessing fire risk during storage, handling, or processing of viscous or high-boiling-point substances. The DFp-303 ensures your products meet OSHA, DOT, and GHS classification criteria while supporting internal quality benchmarks for asphalt binders, gear oils, and marine fuels.

Whether you’re certifying road-grade bitumen or evaluating industrial grease safety, the Cleveland Open Cup Flash Point Tester DFp-303 combines regulatory compliance, operator safety, and laboratory reliability in a single, robust platform.

Test with confidence. Comply with certainty.
