- Plastic storage tubes with caps: Safer than glass tubes, these plastic tubes come with caps for secure closure, reducing breakage risk and facilitating safe handling, storage, and transport. - Test tubes with caps: Reagent tubes with caps provide secure use and storage, helping prevent leaks and contamination during handling and experiments. - Clear tubes with plastic stoppers: Transparent tubes allow easy observation, and each tube is equipped with a plastic stopper to ensure a reliable seal and containment during testing. - Small sample tubes: A practical teaching set that helps illustrate textbook concepts in a concrete, hands-on way, supporting clearer explanations and improved student learning. Applications - Classroom demonstrations and experiments: Use the clear, sealable tubes to show sealing principles, sample handling, and observation tasks in a safe, controlled environment. - Safe storage and transport of small samples: The capped tubes provide secure containment for reagents or samples during storage or movement between locations. - Laboratory training and practice: Ideal for student practice in sealing, labeling, observing, and handling small-volume samples with minimal risk of spills or breakage.
