Deactivated Clear Glass 12 x 32 mm Screw Neck Vial with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk. When working with highly polar analytes that may associate with the polar glass surface, chromatographers choose deactivated vials as the effective vial of choice. These glass vials are treated with gas-phase, reactive organosilane
Ensure optimal performance of your GC instrument with bleed and temperature optimized Aijiren Tech™ BTO and TR-Green Septa. Made of low-bleed silicone, these septa have excellent mechanical properties, are ideal for demanding GC-MS applications, and may be used reliably up to 400 °C.

Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.
Molded Septa are manufactured from high quality, low bleed material that uses the same exclusive LB-2 rubber formulation chromatographers are accustomed to using. Design. Solid Disc. Type. Septa. For Use With (Equipment) Low Bleed GC-MS Columns. Temperature (Metric) Max. 350°C.
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.
Caps & Closures. Liners & Septa. Used in combination with screw cap or aluminum seals. Septa selection that allows easy access to the contents with a syringe. Available in a variety of sizes and materials. Replacement liners are available that provide good chemical resistance.
LCMS Certified Clear Glass 12 x 32 mm Screw Neck Max Recovery Vial, with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk. One of the most important choices you will make during laboratory separations is choosing lab equipment that is consistent with your materials, application, and lab equipment, including your choice in vials.

PTFE/silicone septa are always best. What force is required to penetrate the septum? Generally, silicone septa are more easily pierced than red rubber or butyl septa. For thicker, hard-to-pierce septa, a small gauge (23 gauge) needle may be required, or a stronger S-needle can be used. Preslit septa are the best option for
PTFE-faced silicone rubber septa are autoclavable, resist coring, and are recommended for use in all autosamplers using screw thread vials. Septa and liners can be laminated with PTFE on one or both sides to provide high chemical resistance and a nearly inert barrier between sample and septa material.
United Scientific Supplies. Silicone stoppers are particularly useful due to their inert and nonreactive nature. It will not impair the growth of tissue cultures and resistant to most chemical acids and solvents. Stoppers can be steam sterilized at 15 lbs. pressure. Broad working temperature range of –62 to 232°C.
the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/silicone septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a
