Oxidation Stability Tester LOST-A11 Catalog
Labtron Oxidation Stability Tester assess resistance of petroleum products, lubricants, and fuels to oxidative degradation at temperature upto 380℃. They utilize thermal-controlled chamber to maintain consistent testing conditions for samples. Their programmable timers allow for accurate control over duration of each test cycle. They incorporate pressure sensors to monitor changes in the sample during oxidation. Our Oxidation Stability Tester is applicable for product development, storage and stability studies and comparative analysis.








The tester evaluates the oxidation stability of fuels, oils, and other samples by measuring conductivity changes over time, helping assess product quality and shelf life.
The LOST-A11 maintains a flow rate of 8 to 12 L/h with ±10% accuracy for consistent testing.
It uses an imported PID temperature controller and an electrical heating rod to ensure precise and stable temperature control.
Yes, the tester's software records all test details, including curves, response times, methods, and timestamps. Users can search and filter data easily.
Yes, it allows users to compare multiple test curves using both graphical and numerical displays for detailed analysis.
