Aniline point tester

When sourcing an Aniline Point Tester, you must prioritize ASTM D611 or ISO 2977 compliance to ensure international standardization. Key technical features include automatic heating and cooling rate control, a high-precision PT100 temperature sensor with an accuracy of ±0.1°C, and a photoelectric detection system for automatic determination of the phase separation point. For high-volume labs, look for models with dual-test positions and integrated cooling systems (like Peltier or water-cooled) to reduce cycle times.

Since aniline is a toxic and flammable chemical, the equipment must feature over-temperature protection and automatic power-off functions. Ensure the device has a CE certification for electrical safety. The testing chamber should be made of borosilicate glass or high-grade stainless steel to resist chemical corrosion. Additionally, verify that the supplier provides Material Safety Data Sheets (MSDS) and clear instructions for ventilation requirements during operation.

This instrument is critical in the petrochemical industry for determining the aromatic content in petroleum products. It is widely used for testing diesel fuels, solvents, and base oils. A higher aniline point indicates a lower aromatic content, which is essential for assessing the ignition quality (Cetane Index) of fuels and the solvency power of industrial solvents. It is also a staple in quality control labs for lubricant manufacturing and rubber processing.

The primary risks include damage during transit and calibration shifts. To mitigate this, insist on vacuum-sealed anti-vibration packaging and request a pre-shipment calibration certificate from a third-party lab. Furthermore, ensure the supplier on Made-in-China.com has a 'Diamond Member' or 'Audited Supplier' status to guarantee business legitimacy and reduce the risk of receiving sub-standard components.

Focus your negotiation on after-sales technical support and spare parts availability. Request a 12 to 24-month warranty and ask for a dedicated technical video consultation for initial setup. You should also negotiate for a wear-parts kit (including extra glass tubes and seals) to be included in the initial bulk price to avoid future downtime due to shipping delays for small components.

Aniline Point Testers are classified under HS Code 9027 (Instruments for physical or chemical analysis). Ensure the commercial invoice clearly states the voltage and plug type (e.g., 110V/220V) to avoid electrical incompatibility. For shipping to regions like the US or EU, ensure the wood packaging meets ISPM 15 heat treatment standards to prevent customs delays. Using DDP (Delivered Duty Paid) terms can simplify the process for buyers unfamiliar with local import taxes and laboratory equipment regulations.
