Stainless Steel Buchner Filtering Funnel

• Vacuum Buchner Filtering Funnel

Shanghai HJLab Vacuum Buchner Filtering Funnel is technique whereby suction is applied to a mixture of liquid and solid. It is always ideal whenever there is a need to separate and keep the precipitate safe from a solution by applying the suction technique.

• Advantages Of Using Buchner Funnel Vacuum Filtration

• • Advantages of Using Buchner Funnel 

1. 1. It makes use of readily available Spunbond which comes in varying and effective pore sizes
   2. It uses a suction technique making it faster than gravity filtration.
   3. It is more efficient at removing residual liquid to give out a purer solid than gravity filtration.

• • Disadvantages of using Buchner Funnel

1. 1. The filter paper pores can permit finer solid particles to penetrate during suction.
   2. Not recommended for microscale purposes as it may result in a significant loss of the targeted filtrate
   3. Can only be conducted with a funnel that has flat surfaces like the Hirsch or Buchner funnel.
      
   4. Not suitable for the solvent with low boiling points. Such solvent would just evaporate, while the dissolved solids upon precipitating, would clog up the filter pores and get stuck on the inside of the funnels.
   5. Lastly, this method is not recommended for hot solutions since the solvents in such a case are close to its boiling point.
