Glass used for boiling tubes is made of borosilicate material, which has a low coefficient of thermal expansion. This means that it can withstand sudden changes in temperature without cracking. Additionally, the glass is tempered and designed to withstand high temperatures, making it resistant to thermal shock.
Vacuum tubes are typically made of glass or metal. The glass or metal envelope contains electrodes and is evacuated to create a vacuum inside. The electrodes are made of elements like tungsten or molybdenum.
Neon tubes come in a variety of lengths and, therefore, weights.
Centrifuge tubes are cylindrical containers used to hold samples during centrifugation, a process of separating substances of different densities using centrifugal force. They are typically made of plastic or glass, and come in various sizes to accommodate different volumes of samples.
Glass is commonly used to make various products such as windows, bottles, jars, drinking glasses, mirrors, and light bulbs. Glass is also used in the construction of buildings, car windshields, and in the production of laboratory equipment.
Try using 1/4" plate glass and cut on bar with a width of about 1 1/2" - 2" and the length will be your starting point. Tune the first bar you make to the nearest note and build on from there. The width doesn't really matter when it's being tuned, the length is the important part. You can just leave the width of all the bars the same. The base of the bars can be made of wood or acrylic (for an all clear look). Usually there is a type of felt on the wood that the bars will rest on. Then some may put rubber of foam strips on each side of the bar to let it resonate more. Hope this helped.
You have a range of apparatus like beakers, boiling tubes and stirring rods.
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass

Boiling tubes are used to heat substances to extreme temperatures. Boiling tubes are almost twice the size of regular test tubes. They are designed to allow substances to violently boil without boiling over or exploding out.
The specimen is usually the glass particle in the serum separator tubes.

Bigger, fatter test tubes are usually called boiling tubes.
Blood clotting in test tubes due to glass occurs when the glass surface activates clotting factors present in the blood. The glass can cause physical trauma to the blood cells, triggering the clotting process. This can lead to ex vivo clot formation in blood samples collected in glass test tubes.
You can buy boiling tubes at most scientific supply stores, online retailers that specialize in laboratory equipment, or through educational suppliers. Some common websites include Amazon, Sigma Aldrich, and Fisher Scientific.
