Closed Cup Flash Point Tester AZA1280

Description

Purpose of Tag Closed Cup Flash Point Testing

Flash point testing identifies the lowest temperature at which a liquid emits sufficient vapor to ignite momentarily under controlled conditions. The closed cup method is particularly important for:

• Aviation fuels

• Solvents and light petroleum products

• Volatile fuels and chemicals

• Safety classification for transport and storage

Compared to open cup methods, closed cup testing provides lower and more conservative flash point values, closely reflecting real storage and handling conditions.

ASTM D56 Tag Closed Cup Method

The AZA1280 is designed according to ASTM D56 – Standard Test Method for Flash Point by Tag Closed Cup Tester, applicable to liquids with:

• Viscosity below 5.5 cSt at 40°C

• Viscosity below 9.5 cSt at 25°C

• Flash point below 93°C

The instrument is not intended for cut-back asphalts, liquids forming surface films, or samples containing suspended solids, ensuring full standard compliance.

Advanced Cooling & Temperature Control

One of the key strengths of the AZA1280 is its dual-compressor refrigeration system, which provides exceptional low-temperature performance:

• Rapid cooling of samples down to –50°C

• Ability to reach –60°C from ambient temperature in approximately 30 minutes

• Stable and uniform temperature control throughout the test

This makes the AZA1280 particularly suitable for low flash point fuels and volatile petroleum products.

High Automation & Operational Safety

The AZA1280 is engineered for maximum automation, repeatability, and operator safety:

• Automatic ion ring ignition system with auto ON/OFF control

• Stainless-steel gas piping for long-term durability and stable ignition

• Adjustable heating rates (1°C/min or 3°C/min) as per testing requirements

• Liquid level overflow and filling ports for convenient sample handling

These features minimize operator dependency and reduce the risk of human error during testing.

User-Friendly Interface & Data Management

The system is equipped with a touchscreen LCD interface, allowing intuitive operation and efficient data handling:

• Real-time temperature display

• Unknown flash point detection mode

• Large internal memory capable of storing thousands of test records

• Built-in thermal printer for instant result documentation

This makes the AZA1280 ideal for high-throughput laboratories and compliance-driven environments.
