Mar 17, 2009 · New PRE-CUT Septa for HPLC Applications. Mar 17 2009. In HPLC often slitted or cross-slitted Silicone/PTFE Septa are used, in order to offer a penetration aid for the fairly thick and dull needles used in the HPLC instruments. While the instrument needle requires the slitted septa, the user may run into the risk of concentration changes due 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 non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a
PTFE / Silicone septa (T/S) are the most useful for HPLC applications as they have wide chemical compatibility and low extractables (I recommend them for general purpose use) . These area
PTFE/Silicone/PTFE septa provide superior performance with Aijiren 1050, 1090, , or any autosampler employing a large diameter, blunt tip needle. Part No Description UOM
1 Septa Selection Guide PTFE Recommended for single injection applications Excellent solvent resistance and chemical compatibility Does not reseal upon puncturing Not recommended for long-term sample storage PTFE/Silicone Recommended for multiple injections and sample storage Demonstrates excellent resealing characteristics
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
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
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.
PTFE & Silicone Fabrics - PTFE Manufacturers. There are 10 different PTFE fabric categories, and fabric thickness range from 3 mil to 27 mil. Silicone / Glass Fabrics. offer more flexibility, resist creasing, and have a rubbery non-stick surface. Silicone fabrics can be coated on one or both sides. Fabric . thicknesses range from 7 mil to 35 mil.
