Borosilicate glass culture tubes with round bottoms and screw caps are essential laboratory tools widely used in various scientific applications. Made from borosilicate glass, these culture tubes are known for their superior chemical resistance, thermal stability, and durability. The screw cap design provides a secure seal, ensuring that the contents of the tube are safely contained during experiments, transport, and storage.

Key Features & Benefits:

  1. Superior Durability:
    • Borosilicate glass is known for its excellent thermal stability, withstanding high temperatures and rapid temperature changes, making it ideal for both heating and cooling applications. The glass does not expand or contract easily with temperature fluctuations, ensuring consistent performance and minimal risk of breakage.
    • Resistant to chemical corrosion, borosilicate glass can safely hold a wide variety of chemicals, making it versatile for different experiments.
  2. Round Bottom Design:
    • The round-bottom design ensures that the tube is stable when placed in a test tube rack or holder, offering efficient mixing and even heating when used in laboratory setups.
    • The round bottom also allows for optimal liquid flow during stirring or shaking, ensuring thorough mixing of contents, which is essential for many laboratory applications.
  3. Screw Cap for Secure Seal:
    • The included screw cap ensures a secure seal, preventing contamination or spillage of samples. This is particularly important when handling volatile or hazardous substances or when transporting the tubes.
    • The cap also allows for easy storage, as the sealed tube can be safely stored without the risk of evaporation or contamination. The design is compatible with various autoclaving and sterilization procedures, making it ideal for laboratory safety.
  4. Chemical Compatibility:
    • Borosilicate glass is chemically resistant to most acids, bases, and a variety of organic solvents, making these culture tubes suitable for a wide range of applications in both the biological and chemical sciences.
  5. Ease of Use:
    • The tubes are designed for easy handling and ergonomics, with smooth edges and standardized sizes that fit well in common lab equipment such as test tube racks, centrifuges, and shakers.
  6. Sterilization:
    • Borosilicate glass tubes can be autoclaved at high temperatures, making them suitable for use in sterile environments, particularly in microbiology, cell culture, and biotechnology applications.

Applications:

  1. Cell Culture and Microbiology:
    • In microbiology and cell culture laboratories, borosilicate glass culture tubes are commonly used for growing bacterial, fungal, or mammalian cultures. The screw cap ensures the culture medium remains sterile, preventing contamination and preserving the integrity of the culture.
    • Used for bacterial inoculation, antibiotic susceptibility testing, or viral culture, these tubes are invaluable in microbial studies and medical research.
  2. Chemical Reactions and Storage:
    • The tubes are ideal for conducting chemical reactions in the lab, such as titrations or small-scale syntheses, where controlled heating or cooling is required. Their ability to withstand extreme temperatures makes them suitable for reactions that may involve boiling liquids or freezing.
    • The screw cap allows for safe storage of reactive chemicals and solvents, ensuring they are safely contained until needed.
  3. Sample Storage and Transport:
    • Borosilicate glass culture tubes are commonly used to store biological samples, such as blood, serum, or urine in clinical labs. The screw cap helps prevent contamination during transport and long-term storage, especially in refrigerators or freezers.
    • These tubes can also be used for storing chemicals or compounds in research environments, where contamination must be prevented and materials need to be stored under precise conditions.
  4. Educational Laboratories:
    • Borosilicate glass culture tubes are frequently used in educational settings for demonstrations and experiments, allowing students to visually observe chemical or biological processes. The screw cap feature enables experiments involving volatile or hazardous materials, where a secure seal is necessary for safety.
  5. Industrial and Pharmaceutical Applications:
    • In industries such as pharmaceuticals and cosmetics, these culture tubes are used for quality control testing, especially when dealing with sensitive formulations that need to be mixed, stored, and transported under controlled conditions.
