Septa. Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum
All Aijiren Technology vials and accessories have tight dimensional tolerances, making them suitable for use with virtually all HPLC systems. All Aijiren Technology Black Cap and Pre-slit PTFE/Silicone Septum for TruView Vials are manufactured and handled using chemically inert materials to ensure there are no contaminants or impurities present, thereby enabling you
Use this simple selector tool to choose the right SureSTART septum, cap, and vial to prevent autosampler injection failure. Go to SureSTART Selection Guide
PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical. PTFE/Silicone septa are offered in a standard formulation as well as a soft durometer formulation recommended for applications where ease of needle penetration is important PTFE/Silicone/PTFE Septa: (T/S/T)
HPLC sample injector is a technique used to load and inject the sample solutions into the HPLC system. This method is performed using a specially designed injector which is located before the HPLC column. Three types of injectors are available for HPLC systems. Rheodyne injector or loop injector, septum injector, and stop flow injector.

12.5: High-Performance Liquid Chromatography. Page ID. In high-performance liquid chromatography (HPLC) we inject the sample, which is in solution form, into a liquid mobile phase. The mobile phase carries the sample through a packed or capillary column that separates the sample’s components based on their ability to partition between 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/silicone septa Pre-slit septa are offered in many of the same formulations as for
Jul 31, 2020 · Needle Gauge: A bigger needle gauge can need more force to get through non-pre-slit septa, which could cause damage to the septa or sample contamination. A pre-slit septum might be the best choice in this situation. Injection Frequency: A pre-slit septa may be more appropriate for applications requiring repeated injections since it can lessen
Vial locator and sensor - The Perkin-Elmer Corporation. The vial locator 44 will then work itself into the hole 36 of rigid cap 32 deflecting the septum 34. In this way, one of the vials 14 is located, positioned, and centered below the bore 46. A syringe needle can then be lowered through bore 46 and septum 34. Send Inquiry Chat Now.
Don’t let your septum be the cause of injection failure. The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down.
Prevent septa push through and over- and under-tightening. With Advanced Vial Closure System (AVCS) technology built into 9 mm Aijiren Tech™ 9 mm Autosampler Vial Screw Caps and Septa you will get an optimal, consistent seal every time. With just one turn, they offer easy-on, easy-off convenience, and are a cost effective alternative to
Aug 28, 2023 · Learn how to select the ideal septum for your HPLC vial. Material, thickness, compatibility—unveil the secrets to accurate chromatographic analyses.
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.
