8 Key Features of Glass Vials with PTFE Coated Butyl Rubber Septa

Jan. 26th, 2024
Glass vials with PTFE-coated butyl rubber bulkheads are an essential component in laboratory environments, especially in industries such as pharmaceutical, biotechnology, and environmental sciences. These vials offer a combination of durability, chemical resistance, and reliability that is essential for the storage and transport of delicate samples. Understanding the key features of these vials will help researchers, scientists, and laboratory technicians make informed decisions about their use.

1. Excellent chemical resistance:

Glass vials with PTFE-coated butyl rubber bulkheads are designed to withstand exposure to a variety of chemicals commonly used in laboratory processes. These vials are resistant to corrosive acids, alkaline solutions, organic solvents, and other reactive substances. This superior chemical resistance ensures that samples stored in the vials maintain their integrity and prevent contamination regardless of the external environment.

2. PTFE Coating:

The PTFE coating on the butyl rubber septum acts as a protective barrier, preventing interaction between the sample and septum material. PTFE is known to be inert and non-reactive, making it an ideal choice for laboratory applications where sample purity is paramount. By effectively isolating the sample from the septum material, PTFE coatings help maintain the integrity and quality of stored samples over time.

3. Butyl Rubber Septum:

Butyl rubber septums provide a reliable seal for vials, effectively preventing leakage and minimizing the risk of sample evaporation or contamination. The flexibility and elasticity of butyl rubber allows the septum to form a tight seal around the neck of the vial, even after repeated puncturing during sample removal. This keeps the sample tightly sealed inside the vial, protecting its integrity during storage, transport, and analysis.

4. Low Extractability Level: 

Manufacturers of glass vials with PTFE-coated butyl rubber bulkheads take special care to minimize the level of extractable compounds that may leach into the sample. Through careful selection of materials and manufacturing processes, these vials are designed to have low extractable levels, thereby reducing the risk of sample contamination. This feature is especially important in analytical applications that require high sample purity and minimal interference from foreign compounds in trace analysis.

5. Thermal Stability:

Glass vials with PTFE-coated butyl rubber bulkheads exhibit excellent thermal stability and can withstand a wide range of temperatures without compromising integrity. Whether exposed to extreme heat during the sterilization process or low temperatures during storage, these vials maintain their structural integrity and sealing properties. This thermal stability ensures that samples remain safe and uncontaminated under a variety of environmental conditions and maintains their suitability for downstream analysis.

6. Compatibility:

These vials are compatible with a variety of analytical techniques and instruments commonly used in the laboratory environment. Whether used in gas chromatography, liquid chromatography, mass spectrometry, or other analytical methods, these vials integrate seamlessly into existing workflows. Compatibility with a variety of instruments allows researchers and laboratory technicians to utilize them on a variety of analytical platforms, facilitating efficient sample handling and analysis.

7. Accurate Manufacturing Standards: 

The manufacturer adheres to strict quality control measures throughout the production process to ensure the consistency and reliability of glass vials with PTFE-coated butyl rubber bulkheads. Each vial undergoes rigorous testing to ensure leak-proof seals, dimensional accuracy, and absence of defects. By adhering to precise manufacturing standards, manufacturers ensure the performance and reliability of these vials to meet the stringent requirements of modern laboratory applications.

8. Versatility:

Glass vials with PTFE-coated butyl rubber septums are available in a wide range of sizes, volumes, and configurations to meet the diverse needs and sample volumes of laboratories. Whether storing small amounts of valuable samples or large volumes for routine analysis, researchers can select the appropriate vial size and configuration to meet their specific requirements. This versatility allows these vials to accommodate a myriad of laboratory applications, providing flexibility and convenience to the laboratory professional.
In summary, glass vials with PTFE-coated butyl rubber bulkheads have many important features that make them an indispensable tool in the laboratory environment. From excellent chemical resistance and reliable sealing to low extraction levels and thermal stability, these vials provide the reliability and performance needed to store, transport, and analyze sensitive samples. By understanding and utilizing these critical features, laboratory professionals can effectively utilize these vials across a wide range of scientific endeavors, ensuring the integrity and accuracy of their research and analytical processes.
