The 3D Sphearo™ Ultra-low Adsorption Surface of JET BIOFIL is designed for spheroids (e.g. 3D tumor spheroid) and organoid cultures, providing a variety of product forms such as culture plates, culture dishes, and culture flasks. After the surface of the product is subjected to special gel treatment, the product has extremely strong anti-protein adsorption and anti-cell attachment, and there is almost no cell attachment on the surface, which is conducive to the suspension growth of cells and enables cell spheroid culture in a rapid, consistent, and reproducible manner.
