Oil Analysis

Lub-rref (Bangladesh) Ltd. is the pioneer accredited laboratory for petroleum product testing in Bangladesh as per ISO/IEC 17025:2005, ensuring global acceptance of its test report.

The Laboratory offers maximum test parameters of Lubricating oil, Transformer oil, Fuel and Grease testing services, carried by experienced chemists and robotic equipment. Our services will help you to control contamination of the oil into your equipment through detecting abnormal machine wear & particles. Continuous monitoring and controlling will prevent machine failure that can be caused by fluid contamination, wrong oil and additive degradation.

For cross-check of our test accuracy we regularly participate in global ASTM Cross-check Program.

We also offer advice on sampling and if necessary can provide you onsite sampling Service.
