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
