About Us

L-K Industries is a leading U.S. manufacturer of oil centrifuges and related petroleum sampling and measuring equipment for the crude oil/petroleum, petrochemical, hydrocarbon, agriculture, food processing and medical industries. Our most common equipment includes portable and laboratory oil centrifuges, sample heaters, glass centrifuge tubes, glass thermometers, glass hydrometers, gaging tapes and oil thiefs.

Our original Melton Oil Centrifuge was first manufactured in 1957 and became the basis for ASTM standards still relevant today. Each L-K product conforms to ASTM (American Society for Testing & Materials) and API (American Petroleum Institute) standards.

Our motto is “Demand a Higher Standard”. We strive daily to design, build and maintain products to the highest standards possible. We manufactured the first Class I, Division 2 certified laboratory centrifuge. This classification ensures safe operation in hazardous locations. With the acquisition of Miller-Weber of Texas and relocation of the ISO/IEC 17025 accredited laboratory, we now calibrate glassware and equipment in-house.
