Sediment Extraction Tester AZA1313
The AZA1313 Sediment Extraction Tester from AZA Lab is a precision laboratory instrument engineered for the accurate determination of sediment content in crude oils and fuel oils using the extraction method specified in ASTM D473. Designed for reliability, consistency, and long-term laboratory use, this tester is an essential tool for petroleum refineries, inspection laboratories, and fuel quality control facilities.
Sediment content is a critical quality parameter that directly impacts storage stability, processing efficiency, pipeline integrity, and combustion performance of petroleum products. The AZA1313 ensures precise sediment measurement by extracting insoluble material using toluene, delivering dependable results across sediment concentrations ranging from 0.01% to 0.40% by mass, with capability for higher concentrations when required.
Description
Accurate Sediment Determination by Extraction Method
The ASTM D473 extraction method is widely recognized for its accuracy in quantifying sediment present in crude and fuel oils. The AZA1313 provides uniform heating, controlled extraction conditions, and high-quality condensation, ensuring repeatable and traceable test results.
During testing, the oil sample is dissolved in toluene and heated under controlled conditions. Insoluble sediment is separated and quantified, providing an accurate indication of oil cleanliness and contamination levels. This information is essential for quality certification, refinery processing decisions, and regulatory compliance.
