2. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Consequently, a 1-inch (25 mm) copper pipe had a 1 + 1 ⁄ 8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings. The wall thickness on modern copper is usually thinner than 1 ⁄ 16-inch (1.6 mm), so the internal diameter is only "nominal" rather than a controlling dimension. [13]

3. Dounce homogenizer - Wikipedia

   en.wikipedia.org/wiki/Dounce_homogenizer

   The Dounce homogenizers, devices used for mechanical lysis of tissue or cells, were invented by and named after Alexander Dounce. Invented by and named for Alexander Dounce [1] [2], a Dounce homogenizer or "Douncer", is a cylindrical glass tube, closed at one end, with two glass pestles of carefully specified outer diameters, intended for the gentle homogenization of eukaryotic cells (e.g ...

   Diagram of a typical glazing jack, from a 1901 patent. A glazing jack or glazing machine is a type of machine used for polishing leather.The machine consists of a solid glass cylinder, typically around two inches (5 cm) in diameter and six inches (15 cm) in length, mounted to the end of a rotating or reciprocating arm.

5. Float glass - Wikipedia

   en.wikipedia.org/wiki/Float_glass

   Most window glass in the early 19th century was made using the cylinder method. The 'cylinders' were 6 to 8 feet (180 to 240 cm) long and 10 to 14 inches (25 to 36 cm) in diameter, limiting the width that panes of glass could be cut, and resulting in windows divided by transoms into rectangular panels.

6. Graduated cylinder - Wikipedia

   en.wikipedia.org/wiki/Graduated_cylinder

   For accuracy the volume on graduated cylinders is depicted on scales with 3 significant digits: 100mL cylinders have 1ml grading divisions while 10mL cylinders have 0.1 mL grading divisions. Two classes of accuracy exist for graduated cylinders. Class A has double the accuracy of class B. [4] Cylinders can have single or double scales. Single ...

7. Glass tube - Wikipedia

   en.wikipedia.org/wiki/Glass_tube

   In order to create hollow objects from glass the cylinder shape is a natural starting material. Cylindrical glass tubes have: the lowest surface area and most compact design; highest mechanical strength against pressure and impact; automated further processing due to symmetry. [2] Compared to moulded glass where the process of tube drawing ...
