There are several types of pipets used in laboratories, including volumetric pipets for precise volume measurements, graduated pipets for general measurements, and micropipets for very small volumes. Each type is designed for specific tasks to ensure accurate and reliable results in experiments and research.
The different types of pipets available for laboratory use include volumetric pipets, graduated pipets, and micropipets. Volumetric pipets are used for precise volume measurements, graduated pipets are used for general volume measurements, and micropipets are used for very small volume measurements.
Disposable pipets are used for transferring liquid samples in a laboratory setting. They are convenient for single-use applications to prevent cross-contamination between samples and are commonly used for tasks like measuring and dispensing liquids accurately.
The labels TC and TD mean "to contain" and "to dispense" respectively. What this means is that glassware can either be calibrated for the purpose of containing a solution or for the purpose of transferring and dispensing a solution. Most flasks will be labeled TC while most pipets and burets will be labeled TD.
Plastic transfer pipets are used for transferring small volumes of liquid in laboratory settings. They are disposable and often used for tasks like transferring reagents, samples, or solutions. Their design allows for precise and controlled dispensing of liquids.
In pipets and burets, TC stands for "to contain," indicating the volume of liquid contained when filled to the calibration mark. TD stands for "to deliver," indicating the volume of liquid delivered when emptied to the calibration mark.

Two common types of Beral pipets are graduated pipets, which have volume markings along the length of the pipet, and non-graduated pipets, which do not have any volume markings and are typically used when precise volumes are not required.

The medium used to calibrate To Contain (TC) pipettes is typically distilled water at a specific temperature, such as 20°C. This calibration process ensures accurate and precise volume measurements by accounting for factors like evaporation and meniscus formation.

A blood test to detect the presence of antibodies against a microorganism. A serologic test can determine whether a person has been exposed to a particular microorganism. Versatility- A single pipet-aid can be adjusted to fit the opening of pipets of varying dimensions. This reduces operational costs of the experiment and enables quicker volumetric measurement and transfer of liquids. pipets usually have a volume range from 1 ml to 50 ml and different calibrations can be made to suit the required purpose.
In pipets and burets, TC stands for "to contain," indicating the volume of liquid contained when filled to the calibration mark. TD stands for "to deliver," indicating the volume of liquid delivered when emptied to the calibration mark.
There are several apparatus in a standard chemistry lab. They include beakers, conical flasks, Florence flasks, test tubes, watch glasses, crucibles, graduated cylinders, volumetric flasks, droppers, pipettes, burettes, stands and their components, tongs, forceps, spatulas, scoopulas, thermometers, Bunsen burners, filter papers, spirit lambs, balance, heat resistant mats, glass plates, deflagrating spoons, evaporating dishes, funnels, litmus papers, Pasteur pipets, pipe stem (clay )triangles, reaction plates, wire gauges, stirring rods, strikers/sparkers, test tube brushes, test tube holders, test tube racks, watch glasses and weight boats.
Droppers help to fill volumetric flasks to the mark. They are used in qualitative tests, whereby the accuracy of the amount of solution is not needed. Basically, use them when you need to draw solution from a stock solution (avoiding contamination of the stock) and when you need to fill solutions to a mark (dropwise).
There are many types of pipettes (or pipet), but most are essentially a fancier version of a medicine dropper or eye dropper. They are used in a laboratory to transport and/or measure a specific volume of liquid.Volumetric pipettes allow the user to measure a volume of solution extremely accurately and then add it so something else. They are commonly used to make laboratory solutions from a base stock as well as prepare solutions for titration. They typically only allow you measure one single volume in a particular size pipette (just like with volumetric flasks). Therefore, they come in many different sizes.There are other types of pipettes also, such as a Pasteur pipette, which is not used to measure the volume of the liquid. It is essentially a large dropper, which can be used to remove liquid from one container and add it to another.There are also graduated pipettes, also called a Mohr pipette, which also allow you to measure the volume of the liquid in the pipette, although not as accurately as a volumetric pipette. These use a series of marked lines (as on a graduate cylinder) to indicate the different volumes. These also come in a variety of sizes. These are used much like a burette, in that the volume is found by calculating the difference of the liquid level before and after.All glass pipettes require the use of some kind of additional suction device, typically a pipette bulb (not the Eppendorf pipette or other similar ones, which have a built-in suction mechanism), which is a rubber bulb which sucks the liquid into the pipette and also allows you to drain the pipette in a controlled fashion. A Beral pipette is a one-piece pipette, usually made from flexible soft plastic (polyethylene) that has a built-in bulb on the end.See the Related Questions and Web Links to the left for pictures and more information on pipets and other laboratory equipment.*A piece of laboratory glassware, shaped like a thin tube with a bulge in the middle, that allows better accuracy when measuring certain volumes (hence the range of sizes) e.g. when making solutions or samples for titrations.Function of a pipette: to deliver small and exact volumes of liquids; extremely useful in chemical laboratories.
