What is the function of the file in the laboratory?
A triangular file is often used to stir chemicals, as well as to scratch glass tubing before breaking it.
What is glass tubing and how it is used?
Glass tubing is exactly what it sounds like -- a tube made of glass. Glass tubing comes in all shapes in sizes, with tube diameters or just a millimeter or less up to very large tubes. It can be used for a number of things. I can be used to carry both liquid and gasses. With a triangular file, it is possible to break glass tubing into smaller pieces. Using a hot flame from a Bunsen burner, it is possible to bend glass tubing into other shapes.See the Web Links to the left for more information about how to use glass tubing.

Why is it necessary to use only one direction in cutting a glass tubing?
Cutting in one direction in glass tubing will reduce the places the glass will crack and break. Cutting in multiple directions greatly increases the chance of the glass tubing completely shattering when you break it off.
How do you cut glass tubing?
with a quarter stick
How is glass tubing cut in the chemistry lab?
Glass tubing in the chemistry lab can be cut using a glass cutter or a file. The tubing is scored with the cutter or file, and then snapped along the line where it was scored to get a clean break. It's important to wear safety glasses and gloves when cutting glass tubing to prevent injuries.
What lab apparatuses hold glass tubing?
This is a stand.
What happens when you hold a glass tubing over a Bunsen burner flame?
When a glass tubing is held over a Bunsen burner flame, it heats up and may eventually become soft, losing its shape or melting. This can be dangerous as molten glass can drip and cause burns. It is important to handle glass tubing with caution and use proper equipment for heating.
How dangerous is florscent tubing?
It isn't dangerous until the glass breaks. Broken glass is dangerous. The contents inside the tubing may contain mercury or other chemicals that should not be ingested.
What are the safety precautions and techniques when inserting a glass tubing in a rubber stopper?
never attempt to insert glass tubing that has a jagged end, all glass tubing should be fire polished before its inserted into a rubber stopper. Use water or glycerin as a lubricant at the end of the glass tubing before inserting it into the rubber stopper. ask teacher for proper lubricant. Protect hands and fingers by wearing leather gloves or placing a folded cloth between your hands and the tubing. hold it as close as possible to the part it is inserted to the rubber stopper. always point the tubing away from the palm of your hand that holds the stopper. use a twisting motion and push the tubing into the stopper. At the end of the experiment put on leather gloves or place the folded cloth between your hands and the tubing and remover the stoppers from the tubing to keep them from sticking to the glass. if it wont budge, use lubricant.
What is the purpose of wetting the glass tubing before inserting into a stopper?
Wetting the glass tubing before inserting it into a stopper helps create a better seal by reducing the risk of air pockets. The water acts as a lubricant, making it easier to insert the glass tube into the stopper without damaging either component.
What are the three different ways colored lights can be produce in neon tubing?
1. - Clear glass tubing with neon produces red or reddish-orange; Clear glass tubing with argon produces faint purple. 2. - Some colors are produced by inert gases in tubing with fluorescent powders painted or baked on the inside. 3. - Colored glass may be used in combination with neon or argon, Mercury, and helium to produce other colors
