Syringes and needles, which are not allowed to be sold in pharmacies, are only available at health stations or hospitals.
Syringes can also be used for medical devices, containers, and scientific instruments such as those used in some chromatography to inject through a rubber septum. Injecting gas into a blood vessel will result in an air embolism. The way to remove air from a syringe to avoid an embolism is to invert the syringe, tap it gently, and squeeze out a little liquid before injecting it into the bloodstream.
In settings where precision is not the primary concern for germs, such as in quantitative chemical analysis, glass syringes are still used because of their small margin of error and smooth pushrod movement.
Syringes can also be used to inject some juices into meat when cooking to improve flavor and texture, or into pastries when baking. Syringes can also be used to fill cartridges with ink.
