When it comes to chromatography, the materials you choose for your septa can have a profound impact on the quality and reliability of your results. Among the options available, PTFE/silicone septa consistently outperform alternatives like red rubber and butyl in purity, cost-effectiveness, and resealability.
At Specialty Silicone Products (SSP), we pride ourselves on providing high-quality silicone septa that meet the demanding requirements of chromatography professionals. Keep reading to learn more and contact us to discuss your application.
Purity Matters
Purity is critical in both HPLC and GC applications. PTFE/silicone septa are engineered to minimize extractables, which can interfere with analytical results. Compared to red rubber and butyl, our septa offer significantly lower background and blank values. This ensures that your data is as clean and accurate as possible, even in highly sensitive tests.
To further enhance purity, a thin layer of PTFE is laminated to the side of the septum facing the sample. This barrier limits the exposure of the silicone elastomer to solvents, reducing the risk of contamination while maintaining the chemical integrity of your samples.
Versatility and Performance
PTFE/silicone septa are incredibly versatile, thanks to their customizable formulations. SSP offers options tailored for specific applications, including variations in hardness (durometer) to accommodate different needle types. This adaptability ensures consistent performance across a wide range of chromatographic applications.
With excellent chemical compatibility, low penetration force, and highly effective sealing and resealing properties, these septa are ideal for demanding environments. Whether you’re working with high-throughput or specialized chromatography, these septa provide the reliability and durability you need.
Resealability and Cost-Effectiveness
In applications requiring multiple punctures, resealability is a key consideration. Silicone’s natural elasticity makes it the perfect material for maintaining a tight seal even after repeated needle insertions. Unlike red rubber and butyl, which degrade more quickly, silicone septa provide long-lasting performance, reducing the need for frequent replacements.
When factoring in the extended usability and minimized risk of contamination, PTFE/silicone septa offer excellent value for their cost. This combination of affordability and performance makes them a superior choice for labs seeking both quality and efficiency.
