Introduction
An oxidation stability tester is an instrument used to determine the resistance of materials, such as lubricating oils, fuels, and edible oils, to oxidation under accelerated conditions, and it is used for quality control, product development, and research in the petroleum, chemical, and food industries. Oxidation is a major cause of the degradation of oils and fuels, leading to the formation of acids, sludge, varnish, and other oxidation products that impair performance, and the oxidation stability tester accelerates the oxidation process by exposing the sample to elevated temperature and, in many methods, a stream of oxygen or air, for a specified period; the degree of oxidation is then determined by measuring parameters such as the induction period, the acid number, the formation of precipitates, or the change in properties, depending on the test method, and the results indicate how long the product can resist oxidation under service conditions. Oxidation stability testers are used for testing lubricating oils and greases, for which the rotating bomb oxidation test and similar methods are used; for testing diesel and other fuels; for testing edible oils and fats, using methods such as the Rancimat test, which measures the induction time; for testing transformer oils; and for testing additives, and they are used in oil refineries, lubricant manufacturers, food processing plants, testing laboratories, and research institutions, with features such as precise temperature control, automatic measurement, and data recording. With their importance in predicting product life and performance, oxidation stability testers are essential for quality control and product development.

FAQ
Q1: What testing scenarios is this tester mainly applied to?
A: The oxidation stability tester is used in petroleum refineries, lubricant laboratories, biodiesel production, vegetable oil processing, fuel quality control and research institutions to evaluate the oxidation stability of petroleum products, lubricating oils, biodiesel, vegetable oils, fats and fuels under accelerated oxidation conditions. It supports gasoline and aviation fuel oxidation stability testing, lubricant antioxidant performance evaluation, biodiesel (FAME) oxidation stability assessment per EN standards, vegetable oil and fat shelf-life prediction, fuel storage stability testing, and antioxidant additive effectiveness evaluation. The accelerated method measures the induction period before oxidation onset, providing data for product quality, storage stability and formulation optimization. It is essential for petroleum, lubricant, biodiesel, vegetable oil and fuel laboratories requiring oxidation stability evaluation for product specification, storage stability, antioxidant performance, shelf-life prediction, quality control and regulatory compliance, where oxidation stability is a critical quality parameter affecting product shelf life, storage stability, engine performance, deposit formation and regulatory compliance for fuels, lubricants, biodiesel and edible oils in petroleum, biofuel and food industries.
Q2: What standards does the tester comply with?
A: The oxidation stability tester follows EN 14112 for biodiesel (Rancimat method), ISO 6886 for animal and vegetable fats, ASTM D525 for gasoline oxidation stability, ASTM D942 for lubricating oils, and relevant GB/T standards. The instrument complies with IEC 61010 laboratory safety standards. Temperature, gas flow and timing should be verified per the applicable standard.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The heating bath, gas control, measurement system and controller are covered, while sample tubes, electrodes, filters and tubing are consumables or accessories. Damage from improper use or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with oxidation stability test methods and instrument operation. We provide operation manuals, training and application support. Proper sample preparation, temperature control, gas flow, measurement setup and result interpretation are important for accurate oxidation stability results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Temperature calibration against a reference thermometer recommended every 6-12 months. Gas flow rate verification periodically per the standard method. Measurement electrode (for Rancimat) calibration and condition checked. Sample tube cleanliness verified. Full system performance verification with reference samples recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Sample tubes, electrodes, filters, tubing and calibration standards are available from laboratory suppliers, though instrument-specific parts should be verified. Long-term consumable cost is moderate depending on testing volume.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes number of test positions, test method (Rancimat, pressure differential), temperature range, gas supply and automation level. Additional sample tubes, electrodes and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the tester and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for quality control laboratory setup. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The oxidation stability tester evaluates petroleum products, lubricating oils, biodiesel, vegetable oils, fats and fuels within the method range and temperature specification. Different sample types require specific test methods (Rancimat for biodiesel and fats, pressure method for gasoline, etc.). Samples should be representative and properly stored to avoid pre-oxidation. Users should select the appropriate test method for the sample type, use proper sample volume, control temperature and gas flow per the standard, allow sufficient test duration for the induction period, use clean sample tubes, and report results with complete test conditions including method, temperature, gas flow and induction period. The test involves heating flammable oils with oxygen or air, so proper fire safety and ventilation are required.
