At Specialty Silicone Products (SSP), we understand that every application has unique sealing and material requirements. Our broad manufacturing capabilities combine silicone material expertise, precision converting, molding, and custom fabrication to deliver solutions tailored to specific performance requirements.
If you need custom septa, cap and silicone solutions for demanding applications, our SeptaSource products provide the quality and reliability that you need. Keep reading to learn more and contact us to discuss your application.
Custom Septa Materials, Colors, and Designs
SSP offers custom septa manufactured with a variety of PTFE and silicone color combinations to meet application-specific requirements and identification preferences. Our capabilities include 9mm screw cap molding, friction fit designs, and bonded cap/septa solutions that provide flexibility for a wide range of vial and closure configurations.
Silicone Materials for Demanding Chromatography Applications
SSP’s material expertise allows us to help customers select standard or custom septa based on analytical sensitivity, needle penetration, resealing requirements, and compatibility with their instrumentation.
Septum material selection is critical to achieving reliable chromatographic results. SSP offers specialized silicone septa that are designed to address demanding analytical requirements. Choices include including high-purity Ultra Low Bleed (ULB) septa and EasyPierce™ septa that support multiple piercings with a needle or syringe.
Our Ultra Low Bleed silicones are designed to minimize silicone-related background contributions during analysis. This makes them particularly valuable in gas chromatography (GC) and gas chromatography-mass spectrometery (GC-MS) applications where low background and trace level detection are important. By minimizing potential bleed and background contributions, these materials can help support cleaner chromatographic baselines and more reliable analytical results.
For applications requiring frequent needle penetration, our EasyPierce™ septa are engineered to provide reduced needle penetration force while maintaining effective sealing performance. This can support smoother autosampler operation, reduce mechanical stress on sampling needles, and promote consistent sample introduction. SSP makes autosampler septa and caps that are compatible with a wide variety of today’s laboratory equipment.
Septa Rolls, Sheets and Slitting Capabilities
For customers using automated septa insertion and cap assembly equipment, SSP can manufacture custom septa material in rolls with specific widths to support automated fitting and high-volume production. We also offer standard and custom septa material in sheets and have slitting capabilities for septa materials and cap mats. This enables us to convert materials into specific widths and formats to meet customer requirements for equipment and manufacturing processes.
Our capabilities extend to silicone injection molding for 96 well and 384 well cap mats, providing flexible solutions for high throughput laboratory workflows. Among their advantages, 96 well plates and sealing cap mats are ideal for automated sample cleanup techniques such as solid-phase extraction (SPE) prior to liquid chromatography-mass spectrometery (LC-MS) analysis.
PDMS Membrane Manufacturing
Beyond traditional septa and closures, SSP has the capability to manufacture PDMS silicone membranes for non in vitro applications. PDMS, or polydimethylsiloxane, offers a combination of flexibility, chemical resistance, temperature performance, optical characteristics, and gas permeability that makes it useful in a variety of applications. SSP can produce membrane materials in a variety of configurations and thicknesses to meet specific application requirements.
These thin silicone membranes can be considered for applications such as filtration, gas permeation, separation, sensing, protective barriers, and other industrial or laboratory technologies where PDMS is an appropriate material. Our membrane manufacturing capabilities can be combined with SSP’s broader silicone processing, converting, and custom fabrication expertise to develop application-specific solutions.
Finished Septa for Virtually Any Chromatography Application
SSP manufactures finished septa in a wide variety of thickness and diameters to support diverse vial sizes, closure systems, and laboratory requirements. From standard configurations to highly customized designs, our silicone-based materials and manufacturing capabilities can address virtually any chromatography application where silicone septa are suitable.
Whether the requirement involves a specialized diameter, PTFE/silicone color combination, durometer, or specialized analytical performance, SSP can work with customers to develop a high-quality solution. SSP also makes PFAS-free consumables for chromatography.
Quality, Certification and Documentation for Custom Septa
SSP understands that material performance is only part of the solution. Many customers also require detailed quality documentation in the form of certs or certificates to support their internal quality systems and regulatory requirements. Depending on the product and customer requirements, SSP can provide Certificates of Analysis (COA) and Certificates of Conformance (COC) that document applicable product specifications and conformance requirements.
SSP can also support customer requirements for compliance with Restriction of Hazardous Substances (RoHS), a European Union regulation. RoHS compliance helps customers verify that applicable products meet restrictions on specified hazardous substances. Documentation and certification requirements can be reviewed as part of the quotation and product specification process.
Ultimately, SSP’s quality systems and documentation capabilities provide customers with greater confidence that the materials and products they receive meet their defined requirements and can be appropriately documented within their own quality systems.
One Manufacturer, Multiple Silicone Capabilities
From custom PTFE/silicone septa and molded screw caps to bonded closures, injection molded components, Ultra Low Bleed and EasyPierce™ materials, slit rolls, sheets, cap mats, finished septa, and PDMS membranes, SSP offers a broad range of silicone manufacturing capabilities all under one roof.
Our combination of material expertise, engineering, tooling, manufacturing, and converting capabilities allows us to move from a customer requirement to a practical, production ready silicone solution.
