Glass Test Tubes for Laboratory (6 Inch)

Description

Glass Test Tubes also known as a culture tube or sample tube of lab glassware. Test tube consisting of a finger-like length of glass tubing, open at the top and closed at the bottom side. This test tube is usable in all types of laboratories linking chemistry, biology or bio-sciences, clinical medicine, textile lab, etc. It also uses flower vases, glassware for certain weak shots, or containers of spices, raising queen ants during the first months of development.

Glass test tubes are cylindrical containers typically made from borosilicate glass, designed to hold small amounts of liquids or solids for experimentation and observation in laboratories. They often come with a rounded bottom and an open top, allowing for easy access.

Key Features of Glass Test Tubes:

1. Material: Borosilicate glass is favored for its thermal resistance and durability.
2. Size: Test tubes come in various sizes, usually ranging from 10 mL to 100 mL.
3. Uses: Commonly used in chemistry and biology for mixing, heating, or storing samples, as well as for conducting reactions.
4. Sterilization: They can be sterilized in an autoclave, making them suitable for microbiological work.

Safety Tips:

• Handle with care to avoid breakage.
• Use appropriate protective gear (gloves, goggles) when working with chemicals.
• Ensure that test tubes are clean before use to prevent contamination.

Glass test tubes have a wide range of applications in various fields, particularly in laboratories. Here are some common uses:

1. Chemical Reactions

• Used to mix and heat chemical reagents.
• Suitable for small-scale reactions where precise control is needed.

2. Biological Studies

• Ideal for culturing microorganisms or cells.
• Used in assays and experiments involving biological samples.

3. Sample Storage

• Store liquids or solids for later analysis or experimentation.
• Often used to preserve biological samples.

4. Spectrophotometry

• Used as sample holders in spectrophotometers to measure the absorbance of solutions.

5. pH Testing

• Hold solutions for pH testing using pH meters or strips.

6. Crystallization

• Serve as containers for crystallizing substances, allowing for observation of crystal formation.

7. Filtration

• Can be used with filtration setups, often with a stopper or a membrane.

8. Demonstrations and Teaching

• Commonly used in educational settings for demonstrating chemical reactions and principles.

9. Calibration and Standards

• Hold calibration solutions for instruments or as standards in various experiments.

10. Home Science Projects

• Popular for DIY experiments and educational purposes at home.
