A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the ...
Safety syringe. A safety syringe is a syringe with a built-in safety mechanism to reduce the risk of needlestick injuries to healthcare workers and others. 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.
Pipetting syringes are hand-held devices that combine the functions of volumetric (bulb) pipettes, graduated pipettes, and burettes. They are calibrated to ISO volumetric A grade standards. A glass or plastic pipette tube is used with a thumb-operated piston and PTFE seal which slides within the pipette in a positive displacement operation ...
Used for intravenous injections and cannulation. Microscope. used for visualising minute structures, including microbes. Bunsen burner or spirit lamps or candles. source of fire / heat. Ultracentrifuge. used to separate particles dispersed in a liquid according to their molecular mass. Electrophoresis apparatus.
Syrette. A syrette is a single-use device for injecting liquid through a needle. It is similar to a syringe except that it has a sealed squeeze tube instead of a rigid tube and piston. It was developed by the pharmaceutical manufacturer E.R. Squibb & Sons (eventually merged into the current day Bristol-Myers Squibb) just prior to World War II ...
A gas syringe showing its components separated and assembled. A gas syringe is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. [1] A gas syringe can also be used to measure and dispense liquids, especially where these liquids ...
Domain. Safety signage design. Website. www.iso.org /standard /51021.html. ISO 3864 specifies international standards for safety signs and markings in workplaces and public facilities. These labels are graphical, to overcome language barriers. [1] The standard is split into four parts.
Low dead space can be achieved in detachable syringes and needles through designing either the syringe or needle components to have low dead space. Currently, the design of the low dead space needle incorporates a plastic neck that fits within the neck of a standard syringe hub. A low dead space syringe is accomplished by using a standard ...
