Grease Analysis
Lubricating grease is a solid or semi-solid lubricant composed of three primary components: base oil, thickener, and additives. These components play a critical role in determining the performance and behavior of the grease in various applications.
Base Oil Analysis: The base oil, typically mineral or vegetable oil, serves as the primary lubricating medium. Testing ensures its quality and compatibility with specific applications, influencing the grease's ability to reduce friction and wear effectively.
Thickener Evaluation: The thickener acts as a sponge, holding the base oil and additives in place. Testing methods assess its structure and stability to ensure the grease remains effective under varying temperatures and mechanical stresses.
Additive Performance Testing: Additives enhance the grease's performance by providing properties like oxidation resistance, corrosion protection, and anti-wear capabilities. Testing determines the effectiveness and compatibility of these additives within the grease formulation.
Grease Consistency Testing: Parameters like cone penetration are evaluated to measure the consistency of the grease, ensuring it meets the specific needs of the equipment and operational conditions.
Thermal and Oxidation Stability: Testing methods assess the grease's ability to perform under high temperatures and resist degradation over time, which is critical for maintaining long-term equipment efficiency.
ETLCO's capabilities for lubricant grease analysis include cone penetration testing, Copper Corrosion, Dropping Point, Grease Worker, Oil Separation, Oxidation Stability, Ruler (Linear Sweep Voltammetry), and many more as required.

Asphalt and Bitumen
Asphalt testing refers to a set of procedures and analyses that are conducted to determine the physical properties and performance characteristics of asphalt materials. Asphalt is a petroleum-based material commonly used in the construction of roads, parking lots, and other paved surfaces. Bitumen testing and asphalt testing are closely related, as bitumen is the main component of asphalt. Bitumen testing typically focuses on determining the physical properties and chemical composition of the bitumen itself. In the field of asphalt and bitumen testing, ETLCO offers analysis of key parameters, including cone penetration, Distillation of Cutback Asphalt, Dropping Point, Electrical Conductivity, Flash Point, Mercaptan Sulfur, Saybolt Viscosity, Softening Point in Bitumen, Solubility in Trichloroethylene and many more to meet the client-specific demand.

Coolant Analysis
Coolant testing applications are designed to analyze the condition and performance of coolants used in various systems, such as automotive engines, industrial machinery, or HVAC systems. The goal is to ensure the coolant is effective in heat transfer, corrosion prevention, and freezing or boiling point regulation.
ETLCO has full capabilities in coolant testing, with specific tests conducted to examine properties such as appearance, color, freezing point, pH, conductivity, boiling point, and many more.
