Funnel Tube

Funnel tubes are a type of laboratory equipment commonly used in scientific experiments and procedures. They are classified under the supply class "Laboratory Equipment And Supplies" and belong to the supply group "Instruments And Laboratory Equipment."

Funnel tubes are typically made of glass or plastic and have a conical shape with a narrow stem at the bottom. They are designed to facilitate the transfer of liquids or fine-grained substances from one container to another. The wide opening at the top of the funnel allows for easy pouring or filtration, while the narrow stem helps control the flow of the substance being transferred.

Funnel tubes are commonly used in various laboratory applications, such as:

1. Filtration: Funnel tubes are often used in conjunction with filter paper to separate solids from liquids. The liquid mixture is poured into the funnel, and the liquid passes through the filter paper, leaving behind the solid particles.

2. Transferring liquids: Funnel tubes are used to transfer liquids from one container to another without spillage or contamination. The narrow stem of the funnel allows for precise pouring and minimizes the risk of splashing.

3. Adding reagents: Funnel tubes are used to add reagents or chemicals to a reaction mixture in a controlled manner. The narrow stem of the funnel allows for slow and controlled addition, preventing excessive reactions or spills.

4. Separating layers: Funnel tubes can be used to separate immiscible liquids or layers of different densities. By pouring the mixture into the funnel, the liquids will separate based on their densities, with the denser liquid settling at the bottom.

Overall, funnel tubes are versatile laboratory tools that aid in the efficient and controlled transfer of substances. They are essential for various scientific experiments, research, and analysis conducted in laboratories.
