Sediment Extraction

HK-6531 Sediment Extraction in Crude Oil and Fuel Oil

A knowledge of the sediment content of crude oils and fuel oils is important both to the operation of refining and the buying or selling of these commodities


HK-6531 Sediment extraction in Crude Oils and Fuel Oil. The apparatus conforms to the ASTM D473 Standard Test Method for Sediment in Crude Oils and Fuel Oils by the Extraction Method, is used for testing sediment in crude oils and fuel oils by extraction with toluene.


The precision applies to a range of sediment levels from 0.01 to 0.40 % mass, although higher levels may be determined.

HK-5Y Oil Test Centrifuge

Our HK-5Y conforms to the following ASTM standards, ASTM D1290, ASTM D1796, ASTM D2709, ASTM D4007, ASTM D91, ASTM D96.


This Oil Test Centrifuge is fully programmable allowing automatic configuration to the specified oil test parameters. A four place swing out rotor and universal bucket assembly accommodates low cost adaptors and cushions suitable for borosilicate glass centrifuge tubes of the types specified for oil testing.


This Centrifuge describes the laboratory determination of water and sediment in crude oils by means of the centrifuge procedure.


This centrifuge is used for determining water and sediment in crude oils is not entirely satisfactory. The amount of water detected is almost always lower than the actual water content. When a highly accurate value is required, the revised procedures for water by distillation.
