Manufacturing Process of Glass Burette
 

 

Tips for Using Glass Burette

 

Rinsing: Rinse the burette with the liquid you wish to use. Do this by adding a small amount of liquid into the buret, turning the pipette horizontally and rotating it so that the liquid contacts the entire inside surface of the burette. Let the liquid drain through the stopcock into a waste container.


Support: Place the burette in appropriate support. This can be done by using a burette clamp attached to a ring stand.


Filling: Fill the burette with the titrating solution to be used just above the zero mark (+/- 10mm). Fill the tip of the burette with the solution. If necessary, the funnel can be placed on the upper end of the nozzle to help fill.


Remove air bubbles: The burette should not have air bubbles in the tube after the liquid is filled. If there are bubbles, use rubber or other items that will not break the glass to tap the wall to allow the bubbles to float out of the surface. There may also be air in the channel of the stopcock switch. In this case, the plug should be twisted several times quickly, and the bubble can be discharged.


Initial Reading: Verify that the burette is sealing well. To make a reading of the liquid level in the burette, the reading must be made tangentially to the lower part of the meniscus. Keep your eyes to this level, to avoid parallax errors


Dripping: Open the stopcock and slowly allow the liquid to drain into the receiving vessel until it approaches the end point.


End Point: You may add the titration solution quickly until a few milliliters less than the endpoint. After that, one should be careful when adding the solution, to determine the endpoint accurately. When the appropriate amount of liquid has been delivered close the stopcock and touch the buret to the side of the vessel to remove any partial drops.


Final Reading: Read the volume of the remaining liquid.


Calculation: The volume of liquid delivered can now be calculated by subtracting the Final Reading from the Initial Reading.


Drain: Drain the buret of any excess liquid and rinse it with water to clean it.
