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.
How do you deal with the liquid mercury scattered in laboratory?
Set up a vacuum flask with flexible intake tubing long enough to reach the mercury spill. Use glass tubing on the inside of the flask to reach nearly to the bottom on the intake side. On the other side (the side connected to the vacuum source) make sure the glass tubing reaches just inside the flask, near the top, so that the mercury entering the flask will not simply be sucked into the vacuum source lines. Use a two-holed rubber stopper to accomplish all this. This will give you a mercury vacuum cleaner, so to speak. Use a regulator and be careful to use just enogh vacuum to lift the mercury into the flask.

What is the use of a triangular file?
The most common use of a triangular file in a chemistry laboratory is to score (scratch) and weaken small diameter glass tubing prior to breaking it. This makes the glass a) easier to break and b) more likely to break cleanly where the score is instead of randomly, leaving jagged edges. Pressure is applied on the OPPOSITE side of the score; remember to protect your hands with heavy gloves and/or a thick cloth.Large diameter tubing requires different methods; the "score and snap" technique tends not to work so well.
What are the purposes of test tubes?
A test tube is a glass or plastic tube that is rounded on one end and open on the other. Test tubes are traditionally used in experiments done in labratories and would normally contain a chemical or solution.
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.

I want to use neon glass tubing in some DIY projects...including the making of pipes used for smoking. What is the coating inside neon glass tubing?
1. Fluorescent tubes are filled with argon; neon is only an old legend. 2. The coating is not the same for all the tubes. For details see the link below or ask the plant which produce the tubes.
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.
What are some applications of Teflon tubing?
There are lots of applications for Teflon tubing and it comes in different sizes for different jobs. You can use Teflon tubing for molding tubes and electrical cords.
What is the function of hard glass test tube?
It's actually very simple. Glass tubing is a long, clear tube used as a passage for liquid or gas in experiments. Rubber stoppers are used as plugs in flasks or test tubes. Rubber tubing is often connected to a condenser, which is a laboratory tool used in the process of distillation. The rubber tubing helps cool water to flow in and out of the condenser and helps the heated water vapour in the condenser return to its liquid state.
How is glass tubing cut in the chemistry lab?
We can use a diamond (or other very hard material) knife glass cutter.

Before inserting the glass tubing into a stopper why is it nesessary to use a lubricant?
The purpose is to allow an easy insertion.
What is the function of a triangular file in a laboratory?
Most commonly it's used to score small diameter glass tubing before breaking it so that it will break cleanly instead of shattering. Don't attempt to saw through the tubing with the file. If it won't break cleanly with a light score, you'll need to use a different technique such as scribing followed by thermal shock.
Who would use tubing exercises?
Tubing exercises involve using rubber tubes to provide resistance against your movements; this resistance causes your muscles to work harder than they would need to in order to do the same motion without the tubes. Therefore, tubing exercises are mostly going to be used by people who are trying to build up their strength or muscle mass in a given muscle group (as opposed to people trying to build up their endurance, for example).
What are 2 differences between tubing and sledding?
Water tubing your on water in the summer, snow tubing your on snow during the winter. Water tubing is behind a boat and snow tubing is down a hill. Water tubing has special tubes that are expensive and snow tubing can use any tube. Water tubing you have to wear a type II life jacket by law and snow tubing you don't have to wear anything. Water tubing needs an observer, driver, and the person being towed and snow tubing only need the person on the tube. Also in my personal opinion Water Tubing is awesome! and snow tubing is alright.
