Customer Questions & Answers

  • Question: What materials are used in the StonyLab Test Tube?

    Answer: The StonyLab Test Tube is made from high-quality borosilicate glass, which is known for its excellent thermal and chemical resistance. This makes it ideal for scientific applications. Additionally, the PTFE screw cap ensures an airtight seal, preventing contamination and enabling safe storage of samples. These materials work together to provide durability and reliability, important for both laboratory settings and educational purposes.
  • Question: What are the main uses of the StonyLab graduated colorimetric tube?

    Answer: The StonyLab graduated colorimetric tube is primarily used for experiments requiring precise measurement of liquids, such as in chemistry or biology. The graduated markings allow for accurate volume readings, while the colorimetric feature is useful in analyses that involve color-changing reactions. This versatility makes it an excellent tool for scientists, educators, and students alike, whether for conducting lab experiments or demonstrating physical properties in a classroom setting.
  • Question: Is the StonyLab test tube suitable for high-temperature applications?

    Answer: Yes, the borosilicate glass used for the StonyLab test tube can withstand high temperatures without breaking or deforming. Its thermal stability makes it suitable for various applications such as heating samples in a lab setting. This characteristic is particularly beneficial for experiments involving heating and cooling cycles or when using a Bunsen burner, ensuring safety and reliability in the laboratory.
  • Question: How should I clean the StonyLab test tube after use?

    Answer: To clean the StonyLab test tube, it's best to use a gentle detergent along with warm water. Avoid using abrasive materials that can scratch the glass. After washing, rinsing it thoroughly with distilled water is recommended to remove any residual detergent. For heavy stains or residues, soaking in a diluted cleaning solution can be effective. Keeping the test tube clean ensures accurate results in future experiments and prolongs its lifespan.
  • Question: Can I use the StonyLab test tube for storing chemical samples?

    Answer: Yes, the StonyLab test tube, with its PTFE screw cap, is suitable for safely storing chemical samples. The airtight seal provided by the cap helps to prevent contamination and evaporation of volatile substances. This feature is particularly important in laboratory environments where sample integrity is critical, making it a reliable choice for long-term sample storage in various research or educational settings.
  • Question: What is the capacity of the StonyLab graduated colorimetric tube?

    Answer: The capacity of the StonyLab graduated colorimetric tube typically varies depending on the specific model. Many models come in sizes ranging from 10 ml to 100 ml. Having multiple size options allows you to choose the best fit for your experiments or applications, ensuring that you can work with the precise volumes needed whether you are performing titrations, colorimetric analyses, or other scientific procedures.
  • Question: Is the StonyLab test tube compatible with temperature fluctuations?

    Answer: Yes, the StonyLab test tube is designed to handle temperature fluctuations effectively due to its borosilicate glass construction. This type of glass is less likely to shatter when exposed to sudden changes in temperature. This feature is particularly advantageous in experiments that require rapid heating or cooling, providing peace of mind that breakage will not compromise the experiment or the safety of the user.
  • Question: What is the difference between graduated and non-graduated test tubes?

    Answer: Graduated test tubes, like the StonyLab model, have markings along the side that indicate volume measurements, making them ideal for experiments requiring precise liquid measurements. Non-graduated test tubes lack these markings and are primarily used for holding substances without the need for measurement. Choosing a graduated test tube is essential when accurate readings are important, such as when conducting titrations or mixing solutions.
  • Question: Can the PTFE screw cap be used with other types of tubes?

    Answer: While the PTFE screw cap is specifically designed for the StonyLab test tube, it is generally compatible with other test tubes of similar diameter and threading. However, using it with tubes of different sizes or brands might compromise the airtight seal necessary to prevent contamination. It’s recommended to always match the cap to its corresponding tube to ensure optimal performance during experiments.
  • Question: Where can I buy the StonyLab Test Tube with PTFE Screw Cap in Australia?
