Volumetric Flask

Introduction

Classes of a Volumetric Flask

There are two classes in which a volumetric flask is manufactured – Class A and Class B.

The Class A volumetric flasks have the highest level of accuracy with tighter tolerance limits. They have a unique serial number for traceability. The graduation mark on the flask is accurately placed on the flask. The highest accuracy Class A volumetric flasks have a blue color print for clear glass and white for amber variants. The Class A flasks are individually calibrated with their certification.

The Class B volumetric flasks are used for general purpose and calibrated to a lower level of accuracy. The flasks under Class B have white print on them. Class B flasks lack calibration. These volumetric flasks are generally used in schools.

Lab Filtration Assembly

Introduction

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 the laboratories. This process involves a filter medium, like a 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.

Vacuum Filtration Apparatus

The Vacuum Filtration Apparatus is used to easily filter out the solid, liquid, and gases from the solution with the help of a vacuum pump. The apparatus is made up of fine quality Borosilicate Glass and has a Clamp to hold the funnel.

The apparatus consists of a glass that supports the filter disc and a funnel that sits on top of the base. The entire assembly fits on a filter flask with the help of a rubber stopper. The filter flask serves as a safety barrier to minimize the chance that liquid will be drawn into the vacuum source.
