The process of extracting and injecting a gas or liquid with a needle is known to people as an injection. The front of the syringe cylinder with a small hole and matching piston mandrel is used to inject small amounts of liquid or method into otherwise inaccessible areas when the mandrel draws the liquid or gas out of the small hole in the front of the cylinder and the mandrel squeezes the liquid or gas. What are the syringes used for? Here are some answers.

A syringe is a common medical device.

The appearance of the syringe is an epoch-making revolution in the field of medical appliances. A syringe is a common medical device. As early as the 15th century, the Italian Cartinel put forward the principle of the syringe. Gas or liquid is extracted or injected with a needle. Syringes can also be used to inject medical equipment, and containers, such as some scientific instruments in chromatography, through a rubber diaphragm. Injecting gas into a blood vessel can cause an air embolism. The way to remove air from a syringe to avoid embolism is to turn the syringe upside down, tap it gently, and then squeeze out a little fluid before injecting it into the bloodstream.

Used for injecting liquid medicine or extracting liquid.

Both solid and liquid medicines can be taken with a syringe. Sodium can be extracted with a syringe. Just push the syringe piston out, push out a little bit of sodium, and cut it off with a knife. The advantages of this are as follows: first, the syringe is plastic, so it is not afraid of hurting students. Second, the color of sodium (silvery-white) can be observed for a long time. Third, it is easier to control the size of the sodium blocks taken. Fourth, is the cancellation of the kerosene steps, to eliminate the factors of kerosene interference.

When collecting liquid medicines, syringes can be used instead of rubber droppers. When taking an acidic solution, the metal needles should be removed to prevent a reaction. Used for injecting liquid medicine or extracting liquid.

Used in chemical experiments

Syringes can also be used in chemical experiments to change the pressure in the device, measure gas volume, and so on. In some applications where accuracy is not a primary concern for pathogens, such as quantitative chemical analysis, the glass syringe is still used because of its small error and the smooth movement of the pushrod.

Use syringes in your daily life.

In some applications where precision is not the primary concern of the pathogen, such as quantitative chemical analysis, the glass syringe is still used because of its small error and smooth movement of the pushrod. In everyday life, you can also use a syringe to inject some juice into the meat during cooking to improve its taste and texture, or into pastries during baking. A syringe can also fill a cartridge with ink.
