A buret is a specialized piece of laboratory glassware used to measure the volume of a liquid, typically in milliliters (mL). It consists of a long, thin tube with a stopcock (valve) at one end and a graduation mark (usually in mL) at the other end. The stopcock is used to control the flow of liquid out of the buret.
Burets are used in a variety of laboratory settings, including titrations (a common type of analytic chemistry experiment in which the volume of a liquid reactant is measured and recorded). In a titration, the buret is filled with the liquid reactant (called the titrant) and a known volume is dispensed into a container holding the other reactant (called the analyte). The volume of the titrant needed to complete the reaction is then determined from the volume measurements.
Burets are also used to deliver precise volumes of liquid reagents in other types of experiments, such as those involving chemical reactions or cell culture.
Burets are usually made of glass, although they can also be made of plastic. Plastic burets have the advantage of being less breakable than glass burets, but they are not as accurate. Glass burets are more expensive, but they are the preferred choice for many laboratory applications.
There are two types of burets: analogue and digital. Analogue burets are the more traditional type and are read by looking at the liquid level in the tube and estimating the volume. Digital burets are newer and have a digital display that shows the volume of liquid in the buret.
How to read a buret?
A buret is a tube that is used to titrate a solution. It is calibrated so that you can measure the volume of liquid that is dispensed. To use a buret, you need to know how to read it.
The first thing you need to do is to find the zero mark on the buret. This is the point where the liquid starts to be dispensed. You need to make sure that the buret is level with the zero mark. If it is not, you will not be able to accurately measure the volume of liquid that is dispensed.
Next, you need to take the solution that you are going to titrate and add it to the container that you are going to use for the titration. Make sure that you do not add too much solution to the container. You only need to add enough so that the container is filled to the point where the buret meets the container.
Once you have added the solution to the container, you need to dispense the liquid from the buret. To do this, you need to open the valve on the buret. The liquid will start to flow out of the buret. You need to be careful not to dispense too much liquid. You only need to dispense enough so that the container is filled to the point where the buret meets the container.
Once you have dispensed the liquid, you need to close the valve on the buret. Then, you need to check the volume of liquid that is in the buret. This is the volume of liquid that you have dispensed.
Now, you need to calculate the concentration of the solution that you have dispensed. To do this, you need to know the volume of the solution that you have dispensed and the volume of the solution that you have added to the container.
The concentration of the solution is the volume of the solution that you have dispensed divided by the volume of the solution that you have added to the container.
You can use the concentration of the solution to find the volume of the solution that you need to add to the container. This is the volume that you need to add to the container so that the concentration of the solution is the same as the concentration of the solution that you are trying to titrate.
Types of Burets
There are two types of burets: manual burets and automatic burets.
- Manual burets are the traditional burets that are used in many labs. They require manual control of the stopcock to dispense the liquid.
- Automatic burets, on the other hand, are equipped with a motorized piston that dispenses the liquid. They are more expensive than manual burets but offer higher precision and less variability in measurements.
Automatic burette what is it?
An automatic burette consists of a flask thick with frosted glass gasket, where a burette is placed specially design. This type of burette consists of a concentric glass tube lower.
The upper part of the burette contains a short side tube with two openings, one open and the other connected to a rubber pump, through which air is pumped into the burette flask. A capillary tube transports the solution from the flask to the scaled burette tube, filling it from top to bottom.
A small tube exterior with a stopcock made of needle-ground glass or PTFE allows the emptying of the burette. The level of solution inside the burette is held at a fixed point (which corresponds to the number 0 on the scale) thanks to that the end of the capillary tube is slightly above line 0.
Some burettes they have a second stopcock, which allows to drain the solution directly inside the flask, without having to remove it by hand from it and empty it through the main tap.
Automatic burettes are made of plastic or glass, transparent or amber.
There are four main types of burets: glass, plastic, metal, and disposable.
Glass burets are the most common type of buret. They are made from borosilicate glass, which is resistant to thermal shock and chemicals. Glass burets are durable and have a long service life. However, they are also the most expensive type of buret.
Plastic burets are made from polypropylene or polyethylene. They are less durable than glass burets, but are less expensive. Plastic burets are also resistant to most chemicals.
Metal burets are made from stainless steel or aluminum. Metal burets are the most durable type of buret, but they are also the most expensive.
Disposable burets are made from paper or plastic. They are the least expensive type of buret, but they can only be used once.
Construction of a Buret
Burets are typically made of glass, although plastic versions are available as well. The glass burets are usually made of borosilicate glass, which is resistant to thermal shock and chemical corrosion. They are graduated with markings that indicate the volume of liquid dispensed.
Advantages and Disadvantages of Each Type of Buret
Each type of buret has its own advantages and disadvantages.
Glass burets are the most durable, but also the most expensive.
Plastic burets are less durable, but less expensive.
Metal burets are very durable, but also very expensive.
Disposable burets are less expensive, but can only be used once.
Handling and Maintenance of Burets
Burets are delicate instruments that require proper handling and maintenance to ensure their accuracy and longevity. Here are some tips on how to handle and maintain a buret properly:
- Always handle a buret with care, as it is fragile and can easily break.
- Rinse the buret with distilled water before use to remove any impurities that may affect the accuracy of measurements.
- Never touch the graduation marks on the buret with your fingers, as this can leave oils that affect the accuracy of the measurements.
- Keep the buret clean by rinsing it with distilled water after each use.
- Store the buret in a safe place where it will not be knocked over or damaged.
Buret clamps are devices that are used to hold a burette in place. A burette is a glass tube that is used to measure and dispense liquids. Buret clamps are used to attach the burette to a stand or other support.
To use a buret clamp, first, attach the burette to the stand or other support. Next, position the buret clamp on the burette so that the jaws of the clamp are below the stopcock. Then, tighten the screw on the buret clamp to secure the burette in place.
Buret clamps are made of different materials, including plastic and metal. Some buret clamps have a screw that is tightened by hand, while others have a knob that is turned to tighten the screw. Buret clamps are available in a variety of sizes to fit different burettes.
When selecting a buret clamp, it is important to choose a clamp that is the proper size for the burette and that is made of a material that is compatible with the liquid that will be measured. Buret clamps should be cleaned before and after each use.
Buret clamps are an essential piece of laboratory equipment. By attaching a burette to a stand or other support, buret clamps allow for accurate measurement and dispensing of liquids. Buret clamps are available in a variety of sizes and materials to suit different needs.

A burette support is a device that helps to hold and support a burette in a laboratory. There are many different designs of burette supports, but they all have the same purpose: to allow the burette to be positioned in a way that is both stable and convenient for the user.
The most common type of burette support is the tripod, which is composed of three legs that can be adjusted to different heights. Tripods are very versatile and can be used with a wide variety of burette sizes. They are also relatively inexpensive, making them a popular choice for many laboratories.
Another type of burette support is the clamp, which is designed to attach directly to a table or benchtop. Clamps are less versatile than tripods, but they are often more stable, making them a good choice for use with large burettes.
No matter what type of burette support you choose, it is important to make sure that it is compatible with the type and size of burette you plan to use. Incompatible burette supports can lead to accidents and leaks, so it is always best to check with your lab supervisor or another experienced user before selecting a support.
