Beauty Stem Filtration” typically refers to a closed, sterile filtration set used to process lipo-aspirate into microfat/nanofat for aesthetic applications while minimizing shear and contamination. Systems in this category usually pair Luer-lock syringes (10–60 mL) with inline filters of defined pore sizes (often ~50–200 µm) to wash, decant, and separate oil/blood/tumescent fluid from viable tissue—without open bowls or transfers. Many kits are single-use, EO-sterile, latex-free and made from biocompatible medical polymers; some include stopcocks and check valves for low-pressure, gravity or gentle push-through filtration and optional steps for rinsing with saline. Compatibility notes typically cover standard harvesting cannulas, syringe handles, and reinjection cannulas, with IFU guidance on recommended pressures, volumes, and handling times to preserve cell integrity. Documentation commonly includes CE mark/FDA class, lot traceability, shelf-life, and validated sterilization data; use is intended for trained clinicians in accordance with local regulations.
