Analytical Testing Services
At Poretech Analytical Testing Services, we are committed to helping our customers obtain accurate pore structure information of their materials. Since no single measurement technique works for every sample, it is critical to identify the suitable measurement technique.
Backed by a team of in-house material scientists, we begin by discussing your application, identifying the suitable techniques and providing the most comprehensive results. While Poretech provides you with a detailed report, our Application Scientists are always available to discuss and help interpret your results.
Poretech Analytical Testing Services Division can accommodate a wide variety of samples, including non-wovens, filtration membranes, ceramics, barrier materials, specialty textiles, battery separators, hydrophobic and hydrophilic materials, and many more with different shape, sizes and test conditions. The sample size and consistency requirements may vary with the type of tests and materials to be analyzed. If the test result is urgent, we can also offer priority testing service to analyze your samples and have the results sent to you within 1-2 business days as well.
