Customer Questions & Answers

  • Question: What is the material of the Stonylab Test Tube?

    Answer: The Stonylab Test Tube is made from borosilicate glass, known for its durability and thermal resistance. This material is ideal for laboratory use, as it can withstand extreme heat without cracking. Additionally, borosilicate glass offers excellent chemical resistance, making it suitable for a variety of solutions in scientific experiments. This means you can conduct various tests without worrying about contamination or chemical reactions affecting your results.
  • Question: How does the PTFE screw cap benefit the test tube?

    Answer: The PTFE screw cap provides an airtight seal, which is essential for preventing evaporation and contamination of your samples. PTFE, or polytetrafluoroethylene, has exceptional chemical resistance, ensuring that it won't react with the solutions inside the test tube. This feature is particularly useful when handling volatile or sensitive substances that require prolonged stability. Whether you're performing biological assays or chemical experiments, this secure closure helps maintain sample integrity.
  • Question: What is a graduated colorimetric tube and how is it used?

    Answer: A graduated colorimetric tube is designed with measurement markings that allow for precise liquid volume readings. This is particularly beneficial in experiments requiring accurate measurements for chemical reactions or dilutions. By using a colorimetric tube, you can easily observe color changes that correlate with the concentration of solutions. This is common in fields like chemistry and biology, providing valuable visual tracking of experimental progress.
  • Question: Can this test tube be used for biological samples?

    Answer: Yes, the Stonylab Test Tube is suitable for biological samples due to its sterile properties and high resistance to biological agents. The borosilicate glass is non-reactive, meaning it will not interfere with your samples, making it ideal for cell culture and microbiological analyses. Whether you are conducting enzyme assays or growing microbial cultures, this test tube offers reliable performance for sensitive experiments.
  • Question: What are the typical applications for the Stonylab Test Tube?

    Answer: This test tube is versatile and can be used across various applications, including laboratory experiments, medical tests, and in education settings for scientific experiments. Common uses include mixing solutions, conducting titrations, or storing small quantities of reagents. The graduated markings help in accurately determining volumes, making it an essential tool for researchers, educators, and students engaging in hands-on learning.
  • Question: Is the Stonylab Test Tube compatible with automated systems?

    Answer: Yes, the Stonylab Test Tube is compatible with many automated systems designed for liquid handling and analysis. Its standard size and PTFE screw cap design enable seamless integration into automated workflows, facilitating tasks such as sample preparation or high-throughput screening. This makes it particularly useful in laboratories that rely on robotics for efficiency and precision in experimental processes.
  • Question: How do you properly clean and care for borosilicate glass test tubes?

    Answer: Cleaning borosilicate glass test tubes involves using non-abrasive cleaning solutions or detergents and warm water. It's important to avoid harsh chemicals that can cause damage. After cleaning, rinse thoroughly to ensure no residues remain. To maintain their longevity, store them upright in a dedicated container or rack, away from direct sunlight and extreme temperature changes. Proper care ensures the test tubes remain in optimal condition for accurate experiments.
  • Question: Are the graduated markings on the test tube permanent?

    Answer: Yes, the graduated markings on the Stonylab Test Tube are permanently etched into the glass. This ensures that the measurements remain clear and visible, even after repeated use and cleaning. Unlike printed markings, which may wear off over time, these permanent engravings provide lasting accuracy. This feature is especially important for consistent experiments where precise volume measurements are critical.
  • Question: What sizes of the Stonylab Test Tube are available?

    Answer: The Stonylab Test Tube comes in a variety of sizes to accommodate different laboratory needs. Common sizes range from small tubes for micro-sampling to larger ones suitable for general experiments. Choosing the right size depends on the application, whether for storing reagents, conducting assays, or running multiple tests concurrently. Having multiple sizes on hand can enhance flexibility while maximizing efficiency in your lab work.
