In-line pressure filtration holders are designed for use in pressure applications, either in batch or continuous filtration processes. Suitable for aseptic sampling of liquids or gases at point-of-use. Applications: Low pressure filtration (<71 psi for PP, <42 psi for PFA), ultraclean and sterilize, liquids, aseptic sampling of liquids or gases at point-of-use, and environmental air sampling (PPO 47*). Syringe filter holders: Biofluids, ophthalmics, gas chromatography samples, dust-free lubricants, particulate, and microorganism removal from small samples (≤5ml)?
