Pacific® Oil & Grease Disks

The first-class option for Hexane Extractable Material

horizonestore

US EPA 1664A/B, ISO-11349 and Standard Methods 5520G require the use of n-hexane as the extraction solvent and gravimetry as the determinative technique. Alternative extraction and concentration techniques are allowed, provided that the performance and specifications are met. In addition, QC procedures designed to monitor precision and accuracy are an important part of any good method and are met with Pacific-brand disks.

Pacific Premium O&G SPE Disks

Pacific Premium disks, available in both 47 mm and 90 mm, offer excellent recovery and precision. 

Pacific Premium Oil and Grease SPE Disks provide fast flow rates with dirty samples while offering high recovery values for the oil and grease fraction of the sample. These disks blend various diameters of high quality borosilicate glass micro-fibers; the upper surface of each disk provides a greater porosity, essential for handling particulate heavy samples, and the bottom layer, comprised of smaller micro-fibers and packing material, retains the oil and grease fraction.

Pacific™ SPE Disks

Pacific SPE Disks are economical alternatives to the higher performance Premium Disks, available in both a 47 mm and 90 mm size
