Glass Test Tube Without Graduation is a fundamental piece of equipment in any laboratory, widely used for conducting experiments, observing reactions, and holding small quantities of samples. Unlike graduated test tubes, these are plain, cylindrical tubes without measurement markings, which makes them especially suited for qualitative experiments or procedures where exact volume measurements are not necessary.

Available in Nanyang Chemical:

  • 100ml
  • 150ml
  • 180ml
  • 200ml

Usage of Test Tube :

  • Holding small amounts of liquid or solid samples
  • Conducting qualitative chemical reactions
  • Observing biological or chemical processes

How to Use Test Tube :

  • Place the sample (liquid or solid) inside the glass test tube.
  • If heating is required, ensure the tube is placed securely in a test tube holder or clamp to avoid accidents.
  • Direct the open end away from yourself and others while heating.
  • Handle with care to avoid breakage, and always clean the test tube thoroughly after use to prevent contamination.
  • Store the test tube in a rack or designated storage area.

Application of Test Tube :

  • Used in educational settings for demonstrating simple chemical reactions
  • Ideal for qualitative experiments in research laboratories
  • Used in biological laboratories for sample observation or culture work
  • Suitable for industrial testing and process development

Constructed from high-quality borosilicate glass or standard laboratory glass, these test tubes are resistant to heat, thermal shock, and chemical reactions, ensuring their durability and versatility in various experimental setups. These test tubes are commonly used in chemistry, biology, and physics laboratories. In chemistry, they serve as vessels for mixing reagents, observing chemical reactions, or heating substances. Their rounded bottoms allow for uniform heat distribution, which is critical during heating experiments. In biological studies, they are used to culture microorganisms, observe biological processes, or store biological samples for short durations.

Their smooth, transparent surface facilitates easy observation of the sample contents, making them highly effective for demonstrations and teaching purposes in educational settings. The lack of graduation markings simplifies the design, reducing distractions when observing qualitative changes such as color shifts, gas evolution, or precipitate formation. Using these test tubes requires proper handling to avoid accidents or breakage. Always use a test tube holder or clamp when heating, and direct the open end away from yourself and others. After use, they should be cleaned thoroughly to prevent contamination and stored in a rack for protection.

In summary, Glass Test Tube Without Graduation is an indispensable tool for general laboratory applications, offering simplicity, durability, and versatility for a wide range of scientific experiments and educational demonstrations.
