7510-Test Tube, Flat Bottom

• Made of borosilicate glass, designed with a flat bottom
• High thermal shock resistance
• Designed without a rim
• Used for pathological tests and disintegration apparatus

Here are some common uses of test tubes with flat bottoms:

1. Chemical Reactions:
   • Test tubes with flat bottoms are often used for small-scale chemical reactions. Researchers can mix reagents in the tube and observe the reaction, measure reaction rates, or assess the formation of precipitates.
2. Sample Storage:
   • These test tubes are used for storing liquid samples. The flat bottom allows them to stand securely on a lab bench or in a rack. They are often sealed with a stopper or cap to prevent evaporation or contamination.
3. Heating:
   • Test tubes with flat bottoms can be used for heating small quantities of liquids over a Bunsen burner or other heating sources. The flat bottom ensures stability during the heating process.
4. Centrifugation:
   • Test tubes are compatible with centrifugation equipment, allowing for the separation of components based on density. The flat bottom ensures stability during centrifugation.
5. Mixing and Stirring:
   • These test tubes are suitable for mixing and stirring liquids. They can be used with magnetic stirrers or other mixing devices in various laboratory applications.
6. Observation and Analysis:
   • Test tubes with flat bottoms are often used for qualitative and quantitative analyses. Researchers can visually inspect reactions, measure absorbance or fluorescence, or perform other analytical procedures.
7. Sample Preparation:
   • In analytical chemistry, flat-bottomed test tubes are used for preparing samples for further analysis, such as dilutions or the addition of reagents.
8. Culture and Microbiology:
   • Test tubes are used for culturing microorganisms, preparing agar slants, or conducting small-scale microbiological experiments. The flat bottom provides stability when working with these biological samples.
9. Serological Testing:
   • Test tubes with flat bottoms are commonly used in serological testing, including blood typing and other immunological assays. The tubes provide a stable platform for these diagnostic procedures.
10. Educational Demonstrations:
    • In educational settings, flat-bottomed test tubes are used for various chemistry and biology demonstrations to illustrate principles and techniques.
11. Solvent Extraction:
    • Test tubes are used in solvent extraction processes, where substances are extracted from a sample using solvents. The flat bottom ensures stability during the extraction process.
12. Freezing Samples:
    • Test tubes with flat bottoms can be used for freezing small volumes of liquid samples. The flat bottom allows them to stand securely in a freezer.
