Filtration is a process that helps to separate the three states of matter namely Solids, Liquids, and Gases. Filtration can be done biologically or chemically in laboratories. This process involves a filter medium, like filter paper which helps to easily trap the solid particles and separate them from liquids.
Filtration Methods
General Filtration - This is the most basic form of filtration in which the liquid is poured through a filter medium. This method works on gravity, hence the liquid flows down the funnel and the solid is left on the filter.
Hot Filtration - In this method of filtration, the solution, filter, and funnel are heated up till the crystals are formed during filtration. It is used to prevent the crystallization of other components in a mixture.
Cold Filtration - This method of filtration is used to quickly cool down a solution and form small crystals. It is usually done when the solid is dissolved in the liquid.
Vacuum Filtration - In this method of filtration, a funnel and a hose are used which help to suck the fluid through the filter by creating a vacuum. This speeds up the separation and the solid gets dried.
Glass Filtration Assembly
Funnel - Chemically Resistant Glass Boro 3.3 Funnel is used.
Clamp - Aluminium Spring Clamp is used.
Disc Filters - 3 Types of filters are used: Glass Filter, PTFE-faced Filter, and Stainless Steel Screen Filter.
Flask - Vacuum Filtering Flask with Glass Connector is used.
The filtration apparatus should be stored in sterilizer ovens to avoid a fast cooling rate.
