Shipping Information
A hassle-free alternative to dialysis tubing.
Larger View
Serpent Skin tubing is similar to dialysis tubing, except that it is far less expensive. It simulates a cell wall or cell membrane. The microscopic pores in the cellulose tubing produce a physical selection barrier - a semipermeable membrane. These microscopic holes provide a passageway for small molecules to diffuse through the membrane while blocking the diffusion of larger molecules. Serpent Skin may be used either wet or dry. The equilibrium of particles moving through the membrane can be measured by changes in concentration, osmotic pressure, color, volume or mass. The activities and experiments you can create with this fantastic teaching tool are only limited by your imagination. A sheet of ideas and experiments is included with every order. Sold in 12 meter lengths.
