L-K Industries S12D Borosilicate Glass Short Cone Centrifuge Tubes, Model "D", Extra Marking, 6" Height, 100 cu. ft. Capacity (Pack of 6)

L-K Industries is a market leader in durable, accurate, high-quality glassware. All glass centrifuge tubes conform to ASTM and API standards (ASTM D4007/API MPMS Ch. 10.3, ASTM D96/API MPMS Ch. 10.4, ASTM D1796) and can be used in regulatory environments. The most common application for these tubes is for separation of crude oil and basic sediment and water (BS&W) in centrifuges, but these tubes may be used in other applications including petroleum, hydrocarbons, agriculture, chemicals, etc. The graduated marks are permanently etched to improve visibility and provide longer life. Each centrifuge tube has a unique serial number to provide precise traceability. Custom markings are available for specific applications. The wide-thread and 2-mm thick wall configurations provide durability and high RCF capability. All tubes are inspected, calibrated and marked in-house using volumetric or gravimetric techniques. The newly minted laboratory obtained its ISO/IEC 17025 accreditation and as a result, all glassware is certified in-house. The oil centrifuge tubes come configured with a tooled top with a cork or rubber stopper, a wide-neck thread or standard thread. The tube markings can be measured in milliliters (100-ml) or percentage (200%). When running tests with 100-ml tubes, to determine the BS&W content in the petroleum liquid, the volume of two separate test samples must be added. When working with 200% tubes, the average of the two sample tubes is taken. The tube markings include standard or detailed markings. D Style – Short Cone tubes measure 6 3/8” long and are typically used in Transport models because of limited space; applicable standard(s): API 10.4/ASTM D96, ASTM D4007.
