A straight stopcock burette is used in laboratory settings to accurately measure and dispense liquids. The burette has a stopcock at the bottom that can be opened or closed to control the flow of liquid being dispensed. This design allows for precise volume measurements and controlled dispensing of liquids during experiments.

What is a burette?
A burette is a glass tube with fine gradations and a stopcock at the bottom, used in laboratory procedures for accurate fluid dispensing and titration.
How to handle burrete AND PIPETTE correctly?
To handle a burette correctly, ensure the stopcock is closed when filling the burette and open when dispensing liquid. For a pipette, use a pipette filler to draw liquid into the pipette and dispense by pressing the filler gently. Handle both instruments with care to prevent breakage or spills.
The glassware used to titrate solutions is called?
The glassware used to titrate solutions is called a burette. It is a long, graduated tube with a stopcock at the bottom that allows for precise measurement and control of the volume of liquid added during the titration process.
How do tighten burette clamp on?
To tighten a burette clamp, adjust the screw on the clamp to apply pressure on the burette. Turn the screw clockwise to securely hold the burette in place. Make sure the burette is held firmly but not over-tightened to avoid damaging the glassware.
How do you clean pipette?
First remove all the solid particles from the burette using a scrubber. Then wash the burette with tap water followed by distilled water thoroughly (even the nozzle). Then wash the burette with the solution to be used in the burette.
How do you clean a burette with stopcock stuck in it?
To clean a burette with a stuck stopcock, try soaking the burette in warm water to loosen any residue or buildup. If the stopcock is still stuck, you can try applying a lubricant such as silicone grease around the stopcock and gently tapping it to help loosen it. If these methods do not work, consider seeking help from a professional or replacing the stopcock.
What is a burette?
A burette is a glass tube with fine gradations and a stopcock at the bottom, used in laboratory procedures for accurate fluid dispensing and titration.
How does an acid burette differ from base burette when it comes to its parts?
An acid burette typically has a stopcock that is made of glass and resistant to acidic solutions, such as made from PTFE, to prevent corrosion. It may also have a white background on the scale to help with visibility. In contrast, a base burette may have a stopcock made from materials resistant to basic solutions, like a ceramic or glass stopcock coated with PTFE. Additionally, the scale on a base burette may have a blue background to make it easier to see against basic solutions.
Function of a burette?
A burette, or buret, is a uniform-bore glass tube with fine gradations and a stopcock at the bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement. The buret is commonly used in titrations to measure precisely how much liquid is used.
Why burette used to measure acid?
A burette is used to measure acids or other liquids with high precision because it allows for precise volume measurements to be made. The graduations on the burette make it easy to accurately measure and dispense liquids in small increments, which is important when working with chemicals that need to be measured precisely, such as acids. Additionally, the stopcock valve at the bottom of the burette allows for controlled dispensing and titration.
What is the function of the stopcock in Bunsen burner?
The stopcock on a Bunsen burner is used to control the airflow into the burner. By adjusting the stopcock, you can regulate the amount of oxygen that reaches the flame, which allows you to control the flame size and temperature.
What is an acid burette?
An acid burette is a laboratory glassware instrument used for dispensing precise volumes of acid during titration experiments. It typically has a stopcock at the bottom to control the flow of the acid and a scale to measure the volume of liquid dispensed.
What is a burette and how it is use?
A burette, or buret, is a uniform-bore glass tube with fine gradations and a stopcock at the bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement.The buret is commonly used in titrations to measure precisely how much liquid is used.(see related links)
How to handle burrete AND PIPETTE correctly?
To handle a burette correctly, ensure the stopcock is closed when filling the burette and open when dispensing liquid. For a pipette, use a pipette filler to draw liquid into the pipette and dispense by pressing the filler gently. Handle both instruments with care to prevent breakage or spills.
What are the function of base burette in laboratory?
Base burettes are used for base titrants. Basically this is used in titrations where the analyte is an acid.
What is alkali burette?
An alkali burette is a piece of laboratory equipment used to accurately measure and dispense alkaline solutions, such as sodium hydroxide or potassium hydroxide, during titration experiments. It is typically calibrated to precise volumes and has a stopcock for controlled delivery of the solution.
What do you need to read a small quantity of liquid?
