  • Q
    How is a centrifuge used to test oil quality?
    • A centrifuge uses rotational force (centrifugal force) to separate basic sediment and water (BS&W) from an oil sample. Sediment, water, and oil will “shake out” during the test and separate from one another in accordance with their densities.
    • ASTM and API procedures specify testing parameters such as speed, temperature, and duration to ensure constant and reliable results. LK’s equipment is made in strict compliance to these standards.
    • The centrifuge method is commonly referred to as the “field method” for testing oil quality due to its durability and ease.
