A 3-way syringe/nozzle has separate internal channels supplying air, water or a mist created by combining the pressurized air with the waterflow. The syringe tip can be separated from the main body and replaced when necessary. In the UK and Ireland, manually operated hand syringes are used to inject lidocaine into patients' gums.

The needle on a safety syringe can be detachable or permanently attached. On some models, a sheath is placed over the needle, whereas in others the needle retracts into the barrel. Safety needles [1] serve the same functions as safety syringes, but the protective mechanism is a part of the needle rather than the syringe. Legislation requiring ...
A syringe pump for laboratory use. World Precision Instruments (WPI) SP120PZ. A syringe driver, also known as a syringe pump, is a small infusion pump, used to gradually administer small amounts of fluid (with or without medication) to a patient or for use in chemical and biomedical research. Some syringe drivers can both infuse and withdraw ...
A syringe with a male luer lock fitting, and a needle with female luer lock fitting (purple) which screws into it. The Luer taper is a standardized system of small-scale fluid fittings used for making leak-free connections between a male-taper fitting and its mating female part on medical and laboratory instruments, including hypodermic syringe tips and needles or stopcocks and needles.
A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time. The hypodermic needle also serves an important role in research environments where sterile conditions are required.
A syringe filter (sometimes called a wheel filter if it has a wheel-like shape) is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe filter.
The insulin syringe was the first syringe that is considered low dead space. It was initially created with low dead space for accurate measuring and mixing of fast and slow acting insulin, which had the added benefit of wasting as little of the expensive drug as possible.
Like a ground glass stopcock, the two parts of a gas syringe should preferably not be interchanged with another gas syringe of the same volume, unless told otherwise by the distributor. [3] Gas syringes come in various sizes from 500 ml to 0.25 ml and tend to be accurate to between 0.01 and 1 ml, depending on the size of the syringe.
