47mm 3M Oil & Grease Disk for hexane extraction.

Improved 3M oil and grease disks are optimized to meet EPA Method 1664 requirements. They have a faster flow rate and less filter clogging than competing SPE filters. Revolutionary filters uses a fluoropolymer matrix embedded with C-18 coated particles sandwiched between two layers of polypropylene prefilter material. Tri-laminar construction eliminates the need for costly and messy prefilter materials on most samples.
