Syringe is a device composed of a plunger-cylinder arrangement in which, the working side of plunger is attached to a nozzle through which the fluid is sucked in or forced out under effect of pressure gradient which is positive in case of fluid pumping and negative in case of fluid suction, which is generated by means of plunger which leads out of the cylinder. The syringe is used for sucking or injecting a fluid under pressure hence the device has laboratory and medical applications, in laboratory it’s used to inject metered quantity of chemical into an object for study like fruit, vegetable, microbe colony etc. or to extract samples from liquid substance. In medical field the device is used for variety of applications like cleaning wounds, injecting medicine into blood stream and extracting body fluid samples..
