🔍 What is Vacuum Filtration?
Vacuum filtration is a laboratory technique that uses a vacuum source to draw liquid through a filter more rapidly than traditional gravity filtration. This method is especially useful when filtering fine particles or large volumes of solution.
Key Components:
- Filter flask or vacuum flask
- Buchner funnel or membrane holder
- Filter paper or membrane
- Vacuum pump or aspirator
- Connecting tubing
By applying suction, the liquid is pulled through the filter, leaving the solid residue on top and the clear filtrate below.
⚙️ How Vacuum Filtration Works
- The filter medium (paper or membrane) is placed inside the filtration funnel.
- The mixture of liquid and solid is poured into the funnel.
- A vacuum pump is connected to the flask to create suction.
- The vacuum accelerates the filtration process, separating the solid from the liquid quickly.
This method ensures faster, cleaner, and more precise filtration than gravity alone.
🧬 Applications of Vacuum Filtration in the Lab
Vacuum filtration is widely used in:
| Field | Use Example |
| Biotechnology | Harvesting microbial cultures |
| Chemical Analysis | Purifying reaction mixtures |
| Pharmaceutical Development | Removing impurities from drug samples |
| Environmental Testing | Filtering water and soil extracts |
This technique supports high purity results and efficient sample handling.
