E Style – Capillary tubes are designed for refined products such as gasoline and diesel fuel and measure 8" long.

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, ASTM D2709, ASTM D2273) 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.

The oil centrifuge tubes come configured with a tooled top for a cork or rubber stopper, a wide-neck thread or standard thread with a cap. 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.
