Septa
Septa are essential components in laboratory applications, offering a reliable seal for sample containment and injection systems. These septa are primarily used to ensure the integrity of samples in chromatography and other analytical techniques. PTFE septa, known for their chemical resistance and durability, are among our most popular products.
Lab septa have several advanced features, including high puncture tolerance and excellent resealability, making them ideal for repeated use. The general-purpose septa are designed to provide a secure, contamination-free environment, crucial for accurate and reproducible results.
Our septa are available in a range of sizes and materials to accommodate laboratory needs. Options range from standard to specialized inlet septa, which are suitable for high-temperature applications or aggressive solvents. Many septa also come with accessories such as caps and vials, ensuring complete compatibility and ease of use.
With a wide range of choices, these septa offer versatility and reliability, catering to the diverse requirements of modern laboratories. Whether for routine analysis or specialized research, septa provide the quality and performance needed to achieve precise outcomes.
Also available at Thomas Sci – lab caps, vials, and stoppers.
