What we looked at before launching Peptide Test Filters
Most syringe filters are marketed with the same short spec sheet. We wanted to see whether they were truly built the same.
In addition to testing for proper microbial filtering, we commissioned third party Scanning Electron Microscopy (SEM), which is essentially a very high magnification surface image. On our SEM page, every image is captured at the same settings so you can compare membrane structure directly.
