Example of a stirring rod. A glass stirring rod, glass rod, stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, [clarification needed] with rounded ends.
Different types of graduated cylinder: 10mL, 25mL, 50mL and 100mL graduated cylinder. A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid.
Metric measuring spoons are available in sets, usually between four and six, typically with decilitre (100 ml), tablespoon (15 ml), teaspoon (5 ml) and millilitre measures. [citation needed] For fractional measures, there is often a line inside to indicate "half" or "a quarter", or a separate measure may be included, like 1 ⁄ 2 dl.
A simple plastic measuring cup, capable of holding the volume one cup. A measuring cup is a kitchen utensil used primarily to measure the volume of liquid or bulk solid cooking ingredients such as flour and sugar, especially for volumes from about 50 mL (approx. 2 fl oz) upwards.
(A) A low-form or Griffin form beaker (B) A tall-form or Berzelius beaker (C) A flat beaker or crystallizer Philips beaker which can be swirled like a conical flask. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter. [3]
Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Cobalt glass for decoration. Cobalt glass—known as "smalt" when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt.
Crystallography is a technique that characterizes the chemical structure of materials at the atomic level by analyzing the diffraction patterns of electromagnetic radiation or particles that have been deflected by atoms in the material.
