Kjeldahl Flask, 8000ml
The Kjeldahl flask, also known as the digestion flask, is a round-bottomed flask with a long neck that is used in the Kjeldahl method for determining the nitrogen content of organic compounds. The flask has a narrow neck to prevent loss of volatile ammonia during the distillation process, and a wide body to allow for the addition of large volumes of reagents. The flask is usually made of glass or borosilicate glass, although some versions are made of stainless steel.
The Kjeldahl method is a widely used procedure for determining the nitrogen content of organic compounds. The method involves digestion of the sample in a strong acid solution, followed by distillation of the resulting ammonia-rich solution. The distillate is then titrated with a standard base solution to determine the nitrogen content.
The Kjeldahl flask is an essential piece of equipment for performing this procedure. It is important to choose the right size and type of flask for your needs, as well as to use it correctly in order to obtain accurate results.
When choosing a Kjeldahl flask, it is important to consider the size of the sample you will be testing. Smaller flasks are available for testing smaller samples, while larger flasks are necessary for testing larger samples. It is also important to consider the type of material the flask is made from. Glass or borosilicate glass are both suitable materials, but stainless steel may be necessary for certain applications.
Once you have selected the appropriate Kjeldahl flask for your needs, it is important to use it correctly in order to obtain accurate results. The first step is to add the acid reagent to the flask. The amount of acid required will depend on the size of the sample and the type of acid being used. The next step is to add the sample to the flask and swirl it around to ensure that all of the material is wetted by the acid.
After swirling, it is important to immediately place a stopper on top of the flask in order to prevent loss of volatile ammonia during the distillation process. The flask should then be placed in an upright position on a hot plate or Bunsen burner and heated until all of the solid material has dissolved. Heating should then be continued until boiling begins.
Once boiling has begun, it is important to carefully monitor the temperature and maintain it at between 95-100 degrees Celsius. Boiling should be continued for at least 30 minutes in order to complete the digestion process. After boiling has ceased, it is important to allow the solution to cool slightly before proceeding to the next step.
The next step is to connect the stillhead to the top of the flask and begin distilling off the ammonia-rich solution. Distillation should be continued until approximately half of the original volume remains in the flask. Once this point is reached, it is important to remove the stillhead and replace it with a fresh one in order to avoid contamination of the final product.
After distillation is complete, it is important to allow the solution to cool completely before titrating with a standard base solution. Titration should be performed using an indicator such as phenolphthalein or bromothymol blue. The endpoint of the titration will occur when the solution changes color from pink to colorless. The amount of base required to reach this endpoint will give you the nitrogen content of your sample.
