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.
In fact I found this wiki page by searching 'visking tubing' after having a high school memory and wondering how it was made. The fact that it is a UK educational term is highlighted by the fact that searching for [+visking +tubing -dialysis] finds about 13,000 results, almost all of which are from uk school and university websites.
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.
In the oil and gas industry, coiled tubing refers to a long metal pipe, normally 1 to 3.25 in (25 to 83 mm) in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining ...
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
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.
Cellophane is also used in transparent pressure-sensitive tape, tubing, and many other similar applications. Cellophane is compostable and biodegradable, and can be obtained from biomaterials. [ 1 ] The original production process uses carbon disulfide (CS 2 ), which has been found to be highly toxic to workers. [ 2 ]
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.
