This absorbent filter paper offers complete protection in the laboratory, thanks to its cellulose layer for absorbing liquids and its waterproof polyethylene layer. Double layer: Cellulose layer: A layer of high-purity filter paper allows the absorption of large quantities of liquids Polyethylene layer: Completely waterproof, prevents the liquid from penetrating the surface to be protected. The high purity of the filter paper allows the liquid to be recovered and used. Can be disposed of as disposable paper after use without any harmful impact on the environment. The paper can be burned (the polyethylene layer does not melt but burns).
