Customer Questions & Answers
-
Question:
What materials are used in the MACHEREY-NAGEL 702115 Screw Cap?
Answer: The MACHEREY-NAGEL 702115 Screw Cap is made from high-quality polypropylene, ensuring durability and resistance to various chemicals. The cap features bonded silicone white and PTFE blue components, providing a secure seal that prevents leakage and contamination. The combination of these materials makes the cap suitable for a range of laboratory and industrial applications, such as in chemical or biological sample storage. -
Question:
What are the dimensions of the MACHEREY-NAGEL 702115 Screw Cap?
Answer: This screw cap has an N18 size, with a thickness of 1.3 mm. The dimensions make it compatible with standard laboratory vials and bottles that require secure closure. Its size ensures that the cap fits tightly, providing optimal sealing for preventing evaporative loss and contamination, making it suitable for both laboratory and field applications. -
Question:
What is the hardness of the MACHEREY-NAGEL 702115 Screw Cap and why does it matter?
Answer: The hardness of this screw cap is measured at 55 Shore A, which is indicative of a semi-rigid material. This hardness level is important as it strikes a balance between flexibility and strength, allowing the cap to form a secure seal while also being pliable enough to withstand minor stresses without cracking. This functionality is crucial in applications involving thermal cycles or varying pressure levels. -
Question:
Is this screw cap suitable for storage of aggressive chemicals?
Answer: Yes, the MACHEREY-NAGEL 702115 Screw Cap is designed to withstand a variety of chemicals, making it suitable for the storage of aggressive substances. The polypropylene and PTFE materials are resistant to most acids and bases, allowing for safe sealing of samples in laboratories that work with hazardous materials. This feature is particularly beneficial in chemical analysis, research, and long-term sample storage. -
Question:
Can the MACHEREY-NAGEL 702115 Screw Cap be used in high-temperature environments?
Answer: While polypropylene has a stable heat tolerance, the suitability of the screw cap for high-temperature environments is dependent on specific conditions. For most laboratory applications, it is safe, but extreme temperatures may cause deformation. It is advisable to evaluate the specific temperature ranges of your protocol to ensure the cap meets your application needs, particularly when conducting experiments or processes that generate heat. -
Question:
How can I ensure a proper seal with the MACHEREY-NAGEL 702115 Screw Cap?
Answer: To ensure a proper seal, it is essential to correctly align the cap with the vial or bottle and apply gentle but firm pressure while screwing it on. The bonded silicone and PTFE lining will assist in creating a tight seal, preventing any leakage or contamination. Always ensure that the rim of the vial is clean before sealing, as any residue can interfere with the seal's effectiveness. -
Question:
Are the screw caps reusable, and how should they be cleaned?
Answer: The MACHEREY-NAGEL 702115 Screw Cap can be reused; however, it is essential to clean them thoroughly after use, especially if they have been in contact with volatile or corrosive substances. They can typically be rinsed with appropriate solvents and sterilized as needed. Proper cleaning allows for safe reuse in laboratory environments, enhancing sustainability practices. -
Question:
What is the purpose of the closed top design in the MACHEREY-NAGEL 702115 Screw Cap?
Answer: The closed top design of the MACHEREY-NAGEL 702115 Screw Cap plays a critical role in protecting the contents of the vial from external contaminants and environmental factors. This design not only preserves the integrity of samples but also prevents volatile substances from escaping. It is particularly advantageous for storing sensitive chemicals or biological samples that require an airtight seal for accurate analysis. -
Question:
Where can I buy the MACHEREY-NAGEL 702115 Screw Cap in Aland Islands?
Answer: You can purchase the MACHEREY-NAGEL 702115 Screw Cap through Ubuy. They offer a wide selection of laboratory supplies, including this specific model, ensuring ease of access and reliable service.
