Test Tube With Rim 12X100 (PYREX)

This is a test tube with a rim, sized 12 x 100 mm and made from PYREX® (borosilicate glass), is a common laboratory tool designed for a variety of purposes, particularly those involving small volumes of liquids or solutions. Here’s a breakdown of its features and functionalities:

Description:

• Material: PYREX® is a brand name for borosilicate glass, known for its exceptional resistance to heat, chemicals, and scratches. This makes it suitable for various laboratory applications, especially those involving moderate heating.
• Dimensions: It has a diameter of 12 mm and a length of 100 mm. This smaller size is ideal for tasks requiring smaller volumes of liquid or where handling needs to be more precise.
• Rim: The presence of a rim differentiates it from a regular test tube. This rim creates a lip for pouring or holding the test tube, offering improved control and minimizing the risk of spills, especially when working with small volumes or hot liquids.

Usages:

The rim and borosilicate glass construction make this test tube suitable for a variety of laboratory tasks, particularly those involving small volumes:

• Heating Liquids: Due to its smaller size, it’s not ideal for large-scale heating. However, the borosilicate glass allows for safe heating of small volumes of liquids to moderate temperatures. This can be useful for small-scale reactions or experiments requiring gentle heating.
• Mixing Small Volumes: The test tube can be used for mixing small quantities of chemicals or preparing concentrated solutions. The rim allows for easier stirring and manipulation of the contents without spills.
• Holding Small Samples: It can hold and store small volumes of solutions during experiments. This is useful for tasks where a minimal amount of liquid is needed.
• Decanting Small Volumes: The rim facilitates the pouring of precise amounts of liquids from the test tube into other containers.

Applications:

Due to its focus on handling smaller volumes, this type of test tube finds applications in various scientific fields, such as:

• Microbiology: It can be used for preparing small cultures, performing micro-scale experiments, and holding samples for analysis.
• Chemistry: It can be used for conducting micro-scale reactions, preparing stock solutions of concentrated chemicals, and performing small-scale titrations.
• Biochemistry: This test tube can be useful for isolating and analyzing small quantities of biological materials like proteins or enzymes.
• Environmental Science: It can be used for collecting and analyzing small water samples, conducting micro-scale soil tests, and preparing solutions for environmental analysis.

Safety Note:

• Always wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat when working with chemicals and glassware in a laboratory setting.
