Testing Forms

Please click on the below links to download forms to submit when getting samples tested.



To help understand the best approach for each individual application, customers can send a sample of the fluid, and, if possible, a sample of the solids generated.


Requirements for Sample Sizes:

  • Five gallons of dirty fluid taken from the process to serve as a representative sample of the fluid that would run through the filter

  • One quart of concentrated sludge/solids in a separate container (if possible)



Samples will be used for solids analysis and to determine what size filter may be required for your specific application.


Fill in the highlighted areas of the appropriate test form and return along with an SDS sheet of all constituents.  This must be included before we process the sample.  Once testing is complete, samples will be returned.  Upon sending the sample, please notify Mark Blewitt or 44 (0) 1325 317900.  Call with any questions.


Please ship all samples with completed paperwork to:

Lab test on dirty coolant oil
Filter Lab Testing

The first step to evaluating a client’s separation application is to conduct preliminary tests at our facility on samples provided by the client. This initial testing will determine as a minimum the:

1.) Filter flux rate, 2.) Filtrate cleanliness, 3.) Cake moisture, 4.) Media options



This testing is done free but we request the client to pay for the sample shipping costs to Oberlin Filter. Extensive bench tests or special analytics may require additional charges.
