We offer a variety of GC headspace vials, caps and septa to fulfil your application needs. Our patented vial and cap design incorporates pressure-relief features which guarantee safe operation with the high pressure typically developed during thermostatting. Ordinary vials and caps without these safety features may burst.

For all of your analytical and biological applications, our vials, caps, and septa are made from the highest quality materials. Our portfolio consists of GC vials, caps, and septa. We also offer a choice of caps: Foil-lined urea -- best for airtight seal. Poly-cone line -- best for aggressive reagents. Poly screw cap -- basic plastic cap, no

Septa for GL Caps, Silicone and Silicone/PTFE, Ace Glass Incorporated. These septa are designed to fit the DURAN® open-top cap product family. Available in both silicone and PTFE-faced silicone for good chemical resistance. Caps can withstand 130 °C (266 °F) vapor or 200 °C (392 °F) dry heat.

Type 1 borosilicate glass Clear glass vials with 20mm crimp seal finish are designed to fit most headspace autosamplers Flat bottom vials maximize heating efficiency when used with bottom Round bottom vials are more easily handled by robotic arms that lift the vial from the tray

PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.

The innovative features found on the AVCS cap also give more autosampler compatibility with less autosampler interruptions, as a result of misaligned cap tilting, dislodged septa or septa push through. AVCS caps not only have the most effective seal but they also contain significantly less leachables than bonded caps.

Bonded caps from Specialty Silicone Products (SSP) are made of polypropylene (PP) plastic and bonded to platinum-cured silicone septa that’s easy-to-pierce. To ensure analytical purity, SSP uses a proprietary bonding technology that maintains the septum’s analytical properties.

Headspace vial caps are available in a variety of materials including aluminum, bimetal, and steel; headspace vial cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature varieties. Our headspace vial caps come in either 11 mm, 18 mm, 20 mm or 22 mm sizes.

Natural PTFE/blue silicone – ST3, ST201 Best septa choice when temperatures are over 125°C. Natural PTFE/red silicone – ST3HT High temperature formulated seal with low bleed. Best septa choice when temperatures are up to 300°C. Blue silicone/red PTFE – ST144 Thin 1.4 mm seal with PTFE face.

make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE
