Gas chromatography is a chromatographic technique which is used for separation and analysis of volatile substances. It is mainly used for the compounds which can be vaporized without decomposition. In this technique, the sample is injected into a heated chamber. The sample is converted into vapour and carried by an inert gas through a column. … Read more
Mohr pipette (graduated pipette) is a type of graduated laboratory pipette used to measure and transfer variable volumes of liquid accurately. It is a glass (or sometimes plastic) straight tube with graduation marks along the length. It is different from volumetric pipette because it can deliver different volumes as per the required marking. It is … Read more
Pipette dropper is a simple laboratory device used to measure and transfer small volume of liquid in the form of drops. It is also called as Pasteur pipette or eye dropper. It is used when controlled amount of liquid is required, without using a graduated pipette. It is made up of a narrow glass or … Read more
Repeater pipette is a special type of pipette used to dispense the same volume of liquid many times after a single aspiration. It is also called stepper pipette or multi dispenser pipette. It is used when repetitive dispensing is required in routine laboratory works. It works on positive displacement mechanism in which a piston inside … Read more
Mouth pipette is a laboratory method of pipetting in which the suction is created by mouth to draw liquid into a glass pipette tube like drinking with a straw. It was used for taking and transferring small amount of liquids from one container to another container. The volume taken is controlled by the user by … Read more
Multichannel pipette is a laboratory pipette used to measure and transfer multiple liquid volumes at the same time. It has more than one channel arranged in a straight row and each channel holds its own disposable tip. It is used when same volume is needed to be delivered into many tubes or wells in one … Read more
Pipette filler is a handheld laboratory device used to aspirate (draw up) and dispense a required volume of liquid using a glass or plastic pipette. It is also called pipette controller or pipette gun. It is used to handle liquids safely and accurately during routine lab work. It works by creating a controlled suction (vacuum) … Read more
Volumetric pipette is a slender laboratory glass or plastic pipette used to measure and transfer one fixed volume of liquid with high accuracy. It is also called bulb pipette or belly pipette. It is mainly used when an exact volume is required in analytical works. It has a long narrow tube with an expanded bulb … Read more
Serological pipette is a long graduated pipette used in laboratory to measure and transfer liquid in ml range. It is commonly used for 1 ml to 50 ml volume transfer. It is mostly disposable plastic (polystyrene) and sometimes glass. It has clear graduation markings on the body to monitor the liquid level during measuring. It … Read more
Pipette (Glass Pipettes) is a laboratory instrument made up of a narrow glass tube that is used to measure and transfer a specific volume of liquid from one container to another. It works by creating a suction or partial vacuum above the liquid (using pipette bulb or mouth suction) so the liquid is drawn inside … Read more
