Syringes can also be used for medical equipment, containers, such as some of the scientific instruments in the chromatography through the rubber diaphragm injection. The injection of gas into the blood vessels will cause air embolism. Remove the air from the syringe to avoid embolization by inverting the syringe, tapping lightly, and then squeezing a little liquid before injecting it into the bloodstream.

In the case of some precision, rather than the primary consideration of the pathogen, such as quantitative chemical analysis, due to the smaller error of the glass syringe, the push rod moves smoothly so that it is still in use.

You can also inject some juice into the meat with a syringe to improve the taste and texture when you are cooking meat, or into the pastry when baked. The syringe can also add ink to the cartridge

The syringe syringe can be made of plastic or glass, and usually has a scale indication on the top showing the volume of liquid in the syringe. Glass syringes can be sterilized by autoclaves, but because of the low cost of plastic syringes, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases. The spread of disease in drug addicts, especially HIV and hepatitis, is associated with the re-use of needles and syringes.
