Burette, Laboratory Equipment
Definition:
Burette is a uniform glass tube with smooth graduation and cover at the bottom. This is used in volumetric analysis to measure fluid volume, especially from one of the reagents in a titration. Burette is used when necessary to remove a small volume of liquid being measured, such as for titration. Burette can be used to calibrate the volume of other glass items, such as a measuring cylinder. Most burettes are made of borosilicate glass with a PTFE (Teflon) outlet. Burette is very accurate - 50 cm3 burette has a tolerance of 0.1 cm3 (class B) or 0.06 cm3 (class A). The name of the tool used to hold the burette is a dropper clip.
Burette type:
1. Buret acid
2. Basic Burette
The difference between the two burettes is that the ACID burette can only take acid, and the BASE burette can only take bases.
Procedure:
Burette measures from above because they are used to measure the fluid released at the bottom. The difference between the initial and final volumes is the amount distributed Also used for buretting are buretting syringes. These are calibrated for Volumetric A class tolerances that are equal to or better than traditional burette tolerances. The multilevel buretting tube is equipped with a thumb operated piston and a PTFE seal that glides inside the tube in a positive displacement operation. This arrangement is provided to achieve increased reliability, eliminating the problem of trapping bubbles when filling, leaks, and blockages in the stopcock mechanism. This design also addresses handling safety, economy and versatility when handling volumes between 0.5 and 25 mL. Buretting syringes are arranged in traditional burette holders or used freely. The positive displacement action allows it to handle any laboratory liquid - thick and volatile, hydrocarbons, essential oils and mixtures, with high
idexx indonesia accuracy. Another feature of the syringe buretting is the provision of red lines on the sliding seals that can be read as a substitute for the meniscus, thus eliminating parallax errors, and a strong shape that makes it more resistant to damage and easier to clean.
Use:
1. Used to remove a small volume of fluid measured.
2. Used to measure fluids.
3. This is commonly used in titration.
4. Used mainly in laboratory procedures for accurate discharge and measurement of fluids.
