Ideal for demonstrating key biological processes, this Visking tubing helps teachers bring osmosis and dialysis experiments to life in the classroom or laboratory. Suitable for secondary schools and colleges, it provides a clear, hands-on way for students to explore selective permeability and molecular separation.

• Made from cellulose for effective simulation of biological membranes

• 5 metre length and 14mm diameter for multiple practical uses

• Molecular weight cut-off: 1200–1400 Daltons

• Also known as dialysis tubing

• Visking tubing is also known as dialysis tubing.  It should be stored in a re-sealable polythene bag to retain moisture.
