PTFE/Butyl (Pharma Fix Septa) Aluminum Cap N9306224 PTFE/Red Rubber (red) Aluminum Cap, Star Spring and Septa N9304147 N9302978 PTFE/Silicone (white) Aluminum Cap, Star Spring and Septa N9304146 B4000022 PTFE/Silicone (white) Low Bleed Aluminum, Skived Pressure Relief N9302975 PTFE/Silicone (white) Low Bleed Aluminum, Skived (non-Pressure
The commonly used PTFE/silicone HS septa are typically specified for use up to 200 °C, because at high temperature (>200 °C), septum contaminates begin to dramatically leach out of the silicone layer. A series of siloxane peaks are detectable when using PTFE/silicone HS septa at high temperature. The intensity of the siloxane peaks increases
the process flow. Thus, MicroLiter autosampler vials, caps, septa and inserts are available in a variety of formats, individually, component kits or assembled kits. • Vials with Limited Volume Inserts installed decreases the prep time per sample. • Component kits offer the convenience of one product number for the vial cap and septa.
Both types of silicone and butyl rubber septa have a PTFE barrier layer which faces the sample, which reduces the contact between the sample and the silicone and butyl rubber. Before the PTFE layer is punctured, the chemical compatibility properties of the PTFE will
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.
Screw caps [for use with 2 mL vial (standard opening), thread 8-425] are available for use with sealing septa and solid caps with aluminum liners. Caps are offered in solid phenolic caps that can withstand a maximum temperature of 135 C. Compare this item. 20 mm Crimp Top Aluminum Silver Cap with PTFE/Silicone Septa.
Automated Dilution, IC, pH Accessory, Sample Conductivity Goal Demonstrate accurate and reliable sample dilutions using the Aijiren Tech™ Dionex™ AS-AP Autosampler and outline the use of in-line conductivity measurement with the Aijiren Tech Dionex AS-AP Sample Conductivity and pH Accessory prior to analysis by ion chromatography.
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 that
• Can change to sample from different heights in the vial - A setpoint of -2 mm will sample 1.6 mm from the vial bottom - Range is -2 mm to 30 mm • Example uses: - Samples with sediment (although properly filtering the sample is ideal) - Sampling from higher in the sample vial in liquid-liquid extractions - Small volume sampling

Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]
For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.
Each filter vial is comprised of two parts: the external vial and internal plunger with an integrated filter and cap with a pre-slit PTFE/Silicone septa. Simply, dispense your sample into the external vial and compress the internal plunger to filter. This produces a particulate-free sample ready for analysis. Verex Filter Vials are a standard
The PTFE has resistance until punctured, then the septa will have silicone compatibility. Red PTFE/Silicone/Red PTFE Septa - Qorpak Qorpak Customer Service (800) 922-7558
