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 ...
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 ...
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 ...
A graduated pipette is a pipette with its volume, in increments, marked along the tube. It is used to accurately measure and transfer a volume of liquid from one container to another. [1] It is made from plastic or glass tubes and has a tapered tip. Along the body of the tube are graduation markings indicating volume from the tip to that point.
Depending on the number of pistons in a pipette, there is a differentiation between single-channel pipettes and multi-channel pipettes. For manual high-throughput applications like filling up a 96-well microtiter plate most researchers prefer a multi-channel pipette. Instead of handling well by well, a row of 8 wells can be handled in parallel ...
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.
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.
Vial. A vial (also known as a phial or flacon) is a small glass or plastic vessel or bottle, often used to store medication in the form of liquids, powders, or capsules. They can also be used as scientific sample vessels; for instance, in autosampler devices in analytical chromatography. Vial-like glass containers date back to classical ...
