Distillation Tester LDT-A17

The Distillation Tester LDT-A17 is suitable for testing light to medium petroleum fractions, including gasoline, kerosene, diesel, jet fuel, and similar volatile hydrocarbons. It follows standardized methods like ASTM D86, making it appropriate for both research and regulatory applications. However, it is not intended for testing very heavy oils or high-boiling-point substances unless paired with a vacuum system. Users should ensure the sample falls within the unit’s operational temperature and boiling range for accurate results.

Labtron’s Distillation Tester LDT-A17 uses a vertical glassware assembly with clearly defined temperature zones: the bottom heating zone, the vertical vapor column, and the cooled condenser above. This spatial separation, assisted by gravity and thermal layering, helps form a clean distillation profile where only volatiles with sufficient vapor pressure reach the condenser. The cooling bath ensures rapid phase change at the top, effectively "locking in" the correct boiling point fractions. This design supports highly repeatable cuts and minimizes contamination between boiling stages.

Our Distillation Tester LDT-A17 is designed for standard petroleum-based products and is not intended for highly corrosive substances or chemically aggressive reagents. Using samples that contain reactive chemicals, acids, or solvents outside of petroleum testing norms could degrade seals, gaskets, and internal components. Always confirm sample compatibility with Labtron or consult the material safety data sheets (MSDS) before use. For corrosive materials, specialized distillation equipment with chemical-resistant coatings may be more suitable.

Labtron's Distillation Tester LDT-A17 is a reliable instrument, but common issues can arise from incorrect sample volume, poor thermometer placement, or overheating due to improper heater adjustment. Misreading the distillation volume or neglecting to monitor the endpoint temperature may also result in inaccurate test outcomes. To prevent these problems, operators should strictly follow the Standard Operating Procedure (SOP), perform regular instrument calibration, and ensure proper glassware placement and cleanliness before each run. Using a standardized checklist or operator training guide during testing with this unit can significantly reduce human error and improve overall test accuracy.

The Distillation Tester LDT-A17 heating ramp-up is gradual, and the use of a PID controller allows for slow, even heating, minimizing stress on the distillation flask. In addition, the condenser and bath are kept at stable cold temperatures, ensuring that glass is never exposed to extreme gradients too quickly. For safety, operators are advised to pre-warm glassware to room temperature before starting and avoid sudden power surges that could spike temperatures. These safeguards reduce the risk of cracked or shattered glass during operation.
