Dialysis tubing, also known as Visking tubing, is an artificial semi-permeable membrane tubing [1] used in separation techniques, that facilitates the flow of tiny molecules in solution based on differential diffusion.
The length of the tube (measured from the initial pinch point near the inlet to the final release point near the outlet) does not affect the flow rate. However, a longer tube implies more pinch points between inlet and outlet, increasing the pressure that the pump can generate. The flow rate of a peristaltic pump is in most cases not linear.
Viskase (formerly Visking) is a global corporation based out of Lombard, Illinois, United States that supplies plastic, cellulose, and fibrous film and packaging to the food service industry, including casings for processed meats such as hot dogs and sausages.
Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing.
A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires. The terms " pipe " and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe.
Tubing may refer to: Tube (fluid conveyance), a long hollow cylinder used for moving fluids or to protect cables and wires; Pipe (fluid conveyance), a tubular section used to convey substances that can flow; Piping, a system of pipes used to convey fluids; Plumbing, any system that conveys fluids for a wide range of applications
Tubing is a smaller diameter pipe that is run inside of the production casing. A packer is usually set at the lower end of the casing to prevent formation fluid from entering the annulus between the tubing and the casing. A packer is an elastomer cylinder that forms a pressure seal between the tubing and the casing.
At a time when Visking was the largest producer of polyethylene film in the U.S., Union Carbide acquired Visking in 1956. An antitrust ruling forced the sale of the polyethylene business of Visking to Ethyl Corporation in 1963. Ethyl, known best for its tetra ethyl lead gasoline additive, renamed the division VisQueen. In 1989, Ethyl ...
