Item No.: GUP047MM - SPE - 47mm UltraPrep® Preactivated Disks, 20pk

UltraPrep® Premium Extraction Disks follow Method 1664 for solid phase extraction of oil & grease but eliminate the need for conditioning with a polar solvent.
UltraPrep® Extraction Disks are embedded with a unique hydrophilic C-18 material that does not need to be kept wet, making extraction easier for the laboratory and eliminating any potential of a co-solvent coming into contact with the sample and assuring method compliance.
Similar in design to our proven and reliable UltraFlow™ Filters, UltraPrep® filters have a prefilter layer consisting of coarse glass fibers. The addition of the prefilter layer improves filtration speed and eliminates the need for a separate prefilter.
Extraction Disks are available in 47mm, 90mm and 100mm. 47mm disks are also available in convenient disposable Filter Funnels.
Size: 47 mm
Method: EPA 1664
20 UltraPrep Oil and Grease disks per pack.
