Because they are not expensive, can assure a convenable sealing, are flexible, resist a long time, many reagents doesn't attack rubber, can support temperature in a wide range, the contaminatiom from the rubber is minimal, etc.
Of course rubber stoppers are not recommended for all experiments.
What else can I help you with?
What are the laboratory apparatus of rubber plug?
The main reason for a rubber stopper is to stop gas or liquid from coming out of the container. Rubber stoppers can also prevent contamination of samples by keeping the laboratory glassware safe.
What is the function of a rubber bung?
A rubber bung (also called rubber stopper) is used in the laboratories for test tubes, flasks (made of glass usually). Bungs also used by winery industry for the wine bottles. A bung must fill well as a stopper. The bungs are of many sizes. Rubber bung can have one or more hole(s) for plugging in tube depending on the specification of the procedures. In chemical laboratory, to prevent the liquid chemical leaks or escape the container, we need the rubber bung that fit tightly to the container's open, therefore, the dimension of the rubber bung is concerned. These are some of the sizes that are commonly seen in chemical laboratory
What is the hole in the rubber stopper for?
The hole in a rubber stopper is used to allow for the insertion of glass tubing or a thermometer into a container without disrupting the seal created by the stopper. This allows for measurements or additions to be made to the container while maintaining a closed system.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.
Why are the tubes sealed with rubber stopper rather than left open?
To avoid loss of substances.
What is the use of rubber stopper in laboratory apparatus?

What is a rubber stopper used for and how does it contribute to the functionality of laboratory equipment?
A rubber stopper is used in laboratories to seal containers and apparatus to prevent leaks or contamination. It contributes to the functionality of laboratory equipment by creating a secure and airtight seal, allowing for accurate measurements and controlled experiments.
What are the benefits of using a butyl rubber stopper in laboratory experiments?
Butyl rubber stoppers are beneficial in laboratory experiments because they are chemically resistant, provide a tight seal to prevent contamination, and are durable for repeated use.
Where can you buy a rubber stopper?
You can buy an rubber stopper at widget-co.com. They are not that expansive ethier
What is the volume of rubber stopper?
The volume of a rubber stopper can vary depending on its size and shape. To find the volume of a rubber stopper, you can use the formula for the volume of a cylinder or sphere, depending on the shape of the stopper. Measure the dimensions of the stopper and plug them into the appropriate formula to calculate the volume.
Would a rubber stopper float in water?
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float in water?
Rubber stoppers in the lab what is it used for?
Rubbers stoppers are used in laboratory for: - to close bottles - to close tubes - to make a link between tubes or other laboratory objects - to make link with perforated stopper
Is the density of rubber stopper is denser than the density of water?
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.

When a rubber stopper has a mass of 8.46g was immersed in a graduated cylinder containing 25 ml of water the water rose to 30.9 ml Calculate the densityof the rubber stopper?
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.
