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.
Polypropylene Screw Thread Caps for Chromatography Vials are supplied with a variety of septa already inserted. Caps with PTFE/Silicone/PTFE Septa are good for multiple injections. These septa have PTFE resistance until punctured, then the septa will have silicone compatibility with PTFE/Silicone Septa resist coring and provide great resealability.

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.
Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/silicone septa suitable for all types of chromatographic applications.

Oct 21, 2022 · Oct. 21st, 2022. The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.
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

Standard chromatography vial sizes include 8 x 40mm, 12 x 32mm, and 15 x 45mm. Robotic Arm Machines (R.A.M.) use a non-standard 9mm vial with a magnetic cap. For autosamplers, choose a vial designed for that specific brand. Inserts can be used to decrease the capacity of the vial while maintaining the exterior dimensions.
A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
