Product Overview
The A1101Z Lubricating Oil Oxidation Stability Tester (Metal Bath) is a high-precision laboratory instrument designed for evaluating the oxidation stability of lubricating oils and turbine oils under accelerated conditions.
It is widely used to assess new and in-service turbine oils with identical composition (base oil and additives), as well as to rapidly evaluate the oxidation stability of new mineral insulating oils containing specific antioxidants.
The instrument complies with multiple international standards, including:
NB/SH/T 0193, ASTM D2272, ASTM D2112, ASTM D4742
It is widely applied in petroleum, chemical, electric power, pharmaceutical, commodity inspection, scientific research, and environmental protection industries.
Instrument Features
- Metal Bath Heating System (Eco-Friendly Design)
The A1101Z adopts a metal bath structure, replacing traditional oil bath systems. It eliminates the need for silicone oil, avoids oil fumes and environmental pollution, reduces noise, and ensures a cleaner laboratory environment. No oil replenishment or complex cleaning is required after testing, making operation safer and more efficient. - Independent Single-Unit Operation
Each unit operates independently, allowing fast test turnover. When multiple units are used, laboratory efficiency can be significantly improved. - Multi-Channel Control Capability
The system supports simultaneous or independent control of up to 4 testing units, enabling flexible laboratory operation and high throughput testing. - Simple Venting System
No fume hood is required. Exhaust gases and odors can be safely discharged through a plastic tube, ensuring a simple and convenient ventilation solution. - Multiple Safety Protection Systems
Equipped with over-temperature protection, pressure protection, pressure release protection, and alarm systems to ensure safe operation and protect laboratory personnel. - Data Recording & Storage Function
Supports printing of test results and internal storage of experimental data for traceability and analysis. - Multiple Data Acquisition Interfaces
Supports both network port (LAN) and USB data export for easy data management and integration.

Working Principle
The A1101Z Oxidation Stability Tester evaluates oil oxidation resistance by placing a lubricating oil sample into a sealed pressure vessel filled with oxygen under controlled temperature conditions.
The vessel is heated using a metal bath system and rotated at a constant speed of 100 ± 5 r/min. During the test, oxygen reacts with the oil sample under high temperature and pressure.
The internal pressure is continuously monitored by a high-precision sensor (0–2 MPa, accuracy 0.1 grade). The oxidation stability is determined by the time required for a specified pressure drop.
A longer induction period indicates better oxidation resistance and longer oil service life.

Frequently Asked Questions (FAQ)
What is ASTM D2272 RPVOT test?
ASTM D2272 is a standard method for measuring the oxidation stability of lubricating oils using a rotating pressure vessel (RPVOT). It evaluates oil resistance to oxidation under high temperature and oxygen pressure.
What is the difference between A1101Z and A1100?
A1101Z is fully compliant with ASTM D2272 RPVOT standards and uses a metal bath system, while A1100 is designed for general oxidation stability testing without full RPVOT standard configuration.
What oils can be tested with A1101Z?
It is suitable for turbine oil, hydraulic oil, insulating oil, and other industrial lubricants requiring oxidation stability evaluation.
Does A1101Z comply with international standards?
Yes, it complies with ASTM D2272, ASTM D2112, ASTM D4742, and NB/SH/T 0193 standards.
Is OEM customization available?
Yes, LabVV provides OEM branding, software customization, and distributor cooperation support.
