What is a Thistle Tube?
A thistle tube is made from glass. It has a wide, funnel-shaped top, which is where you pour the liquid. Below the funnel, there is a long, thin tube. This tube allows the liquid to flow down slowly and precisely.
How Does a Thistle Tube Work?
When you pour liquid into the funnel part, it travels down the long, narrow tube. The liquid comes out of the thin end in small drops. This design helps scientists add just the right amount of liquid. It is very useful when you need to be exact with your measurements. For example, you might use it to add acid to another chemical in a controlled way.
Where Are Thistle Tubes Used?
Thistle tubes are common in chemistry and biology laboratories. They are often used in experiments where liquids need to be added slowly. This helps to control reactions or mix solutions carefully. They are a simple but important tool for many scientific tasks.
