Surflay - Model Microbubbles - Air-Filled Polyvinyl Alcohol Capsules
Air-filled polyvinyl alcohol capsules in sizes ranging from 3-4 μm are produced in Surflaylabs. Thanks to a special cross-linking procedure, these bubbles are stable for months, hydrophilic and uncharged. Due to their low density, they slowly float in water to the top.
