Tribology is defined as the science and technology of surfaces in contact and in relative motion. It is the science that studies friction, wear, lubrication.
High Frequency Reciprocating Rig (HFRR-ADV)
The Paltro HFRR-ADV is a fully automated benchtop system designed to assess the lubricity of diesel and biodiesel blends. Thanks to its exceptionally compact footprint, it takes up minimal bench space while delivering automatic load application, digital humidity regulation that relies solely on distilled water, and real-time electronic calibration. Every stage of the test is handled automatically, ensuring complete data traceability from start to finish. The instrument meets the ASTM D6079, ISO 12156 and ASTM D7688 requirements.
Ball on Cylinder Lubricity Evaluator (BOCLE-ADV)
The Paltro BOCLE-ADV is an advanced ball-on-cylinder lubricity analyzer developed specifically for aviation fuels. It brings mechanical assessment and optical imaging together in a single platform, automatically driving each step of the procedure — from sample pre-treatment through to the continuous data logging that guarantees traceability. After pre-treatment, the weights are loaded automatically, the test sequence runs on its own, and up to 10 ring tests can be carried out in a single session. The analyzer conforms to the ASTM D5001 standard.
4- BALL & SHEAR STABILITY:
According to the ASTM D2266 & D4172 methods (with Wear Loading Kit 19940-0), ASTM D2596, ASTM D2783, CEC L-45-A-99, EN ISO 20623, IP 239, IP 300 Procedures A and B (obs), ISO CD 11008
SETA – SHELL 4 BALL LUBRICANT TESTER determines the frictional properties of oils and greases at extreme pressure. Used in tribological research laboratories and quality control laboratories for routine analysis of finished products for lubrication.

SHEAR STABILITY HEAD
According to the CEC methods L-45-A-99, ISO 26422.
It is mounted on the SETA – SHELL 4 BALL LUBRICANT TESTER instrument to determine the loss of shear viscosity.

PIN or BALL ON DISK TRIBOMETER
The tribometer is an instrument that allows the user to measure the friction coefficient (static or dynamic) and the wear of materials that flow on each other, even in the presence of a fluid medium (lubricating oil, grease, water, etc.), by modifying the applied load, the mutual sliding speed and the temperature during the test. According to ASTM G99 methods.
