Purchase Xenosep® Oil and Grease SPE Filters, Prefilters and/or Extraction Apparatus for use in EPA Method 1664A and
if you are unable to completely filter your toughest sample in 10 minutes or less, simply return the Extraction Apparatus
and/or any unused prefilter/SPE filters for a full refund. It's that simple.

Additionaly if you do happen to find a sample that is too tough to filter, we would like to know about it so we can develop a new product
to be able to filter it in 10 minutes or less. Please send 4 x 1 liters of the sample with your contact information to:
