About This Product
Once a small amount of the solution is dragged quickly upwards with a spatula or spoon, the liquid continues to move out of the beaker on its own. This gives a clear demonstration of viscoelastic, elastic-liquid behaviour and long-chain polymer interaction. Propan-2-ol is flammable and is handled by trained staff away from flames and heat.
