FAQs
Q: What is a micro burette?
A: Category: LAB TOOLS. Sub-Category: GLASSWARE. A micro burette in engineering testing laboratories is a smaller, more precise version of a standard burette, used for dispensing very small volumes of liquid in titration or other precise liquid measurement experiments.
Q: Does burette measure fixed volume?
A: Volumetric pipettes are specially calibrated to deliver a fixed volume of solution. You fill the pipette with a pipette filler to the fill mark, then release the solution into a conical flask. Burettes are graduated (they have measurement lines) and deliver a variable volume of solution.
Q: What is a burette used to measure the volume of?
A: burette, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
Q: What are the different types of glass burettes?
A: There are two main types of burette; the volumetric burette and the piston burette. A volumetric burette delivers measured volumes of liquid. Piston burettes are similar to syringes, but with a precision bore and a plunger. Piston burettes may be manually operated or may be motorized.
Q: Why is a burette better than a pipette?
A: Unlike a burette, the pipette is not intended to measure the volume of liquid used, but rather to ensure the volume delivered. In chemistry, a burette is a cut-glassware used in the Laboratory to deliver volumes of liquid, especially during Titrations.
