Test Tube With Rim 24X150 (SIMAX) – Boiling Tube

This is a test tube with a rim, sized 24 x 150 mm and made from Simax glass, is also known as a boiling tube. Here’s why:

• Material: Simax glass is a type of borosilicate glass, known for its similar properties to PYREX®. It boasts excellent resistance to heat, chemicals, and scratches, making it suitable for laboratory applications.
• Dimensions: The 24 mm diameter and 150 mm length provide a good balance between capacity and handling ease for liquids.
• Rim: The presence of a rim is the key feature that distinguishes it from a regular test tube. This rim creates a lip for pouring or holding the boiling tube, offering improved control and minimizing the risk of spills, especially when working with hot liquids.

Why it’s called a Boiling Tube:

Boiling tubes are specifically designed for heating liquids to boiling or near boiling temperatures. Here’s what makes them better suited for this task than regular test tubes:

• Durability: Borosilicate glass, like Simax, can withstand higher temperatures than regular glass used in some test tubes, reducing the risk of breakage when heated.
• Rim: The rim provides a secure grip and prevents spills when pouring hot liquids from the boiling tube.
• Larger size: Boiling tubes are often wider than regular test tubes, allowing for a larger volume of liquid to be heated safely. This can be important for experiments requiring a larger sample size.
