Glass Vacuum Filtration
Single-branch glass, 3-branch glass, or 6-branch glass vacuum filtration provides an efficient extraction device. Hawach Scientific Co., Ltd glass vacuum filtrations can process multiple samples at the same time, without polluting each other, improving work efficiency. Glass vacuum filtrations use a special hard high-quality glass material that resists extremely poor temperature changes of up to 280 degrees Celsius.
Glass vacuum filtration is a widely employed technique in laboratories for separating solid particles from liquid solutions. It utilizes a vacuum source to facilitate the filtration process, allowing for efficient removal of particulate matter. This method is particularly valuable in applications where precise separation of solids from liquids is crucial. The key components of a glass vacuum filtration setup include a filter flask, a Buchner funnel fitted with filter paper, a rubber stopper with a hole, and a vacuum source such as a vacuum pump or aspirator.
| No. | Branch | Funnel Size | Funnel | Support Screen | Screen Pore Size | Connection | Flask | Price |
| SLOGF03001 | 1-branch | 300ml | Glass | PTFE | 20μm | Ground Joint | 1000ml | |
| SLTGF03001 | 3-branch | Glass | PTFE | 20μm | Ground Joint | |||
| SLSGF03001 | 6-branch | Glass | PTFE | 20μm | Ground Joint |
The procedure begins with the preparation of the filter flask, which involves ensuring it is clean and dry, and inserting a rubber stopper with a hole into the neck. A Buchner funnel, equipped with filter paper, is then connected to the flask. The vacuum source is attached to the flask, creating a vacuum that aids in the filtration process. The mixture to be filtered is poured into the Buchner funnel, and as the vacuum is applied, the liquid is pulled through the filter paper, leaving behind the solid particles. The filtrate, which is the liquid that has passed through the filter paper, is collected in the flask.
Glass vacuum filtration is a versatile technique with applications in various fields, including chemistry, biology, and environmental science. It is used for tasks such as isolating crystals from a solution, separating precipitates from a reaction mixture, and testing the presence of particulates in liquids. Its efficiency, simplicity, and reliability make it an indispensable tool in laboratory work.
