Rubber septa Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack. Types of rubber septa PTFE/red rubber – AC6, 6RT1

High Recovery Vials & Vial Inserts Aijiren's broad range of high recovery vials (also referred to as high recovery HPLC vials) are the vial of choice when working with limited sample volumes but not wanting to manually combine a standard 2 mL vial with a separate vial insert.

Septal abscesses are a delayed complication of nasal trauma. It is common to have progressive worsening bilateral nasal obstruction with increasing pain, headache and malaise. There may be fevers and purulent nasal discharge. Examination findings are similar to septal haematomas.

With Hamilton’s new line of GC septa there is evidence that indicates the Point Style AS will consistently extend septa life by as much as 10-fold. Manual HPLC Injections: Most manual injection valves are designed to be used with a 22 gauge Point Style 3 needle.

Dec 21, 2021 · The preslit vial cap should be used when a very low sample volume is being injected. Having the preslit septa helps ensure reproducibly in sample draw from the vial. The preslit septa are compatible with different autosampler injector needle materials like PEEK and metal-tipped.

Jul 23, 2020 · In HPLC analysis, Septa is usually placed in the Cap of the HPLC Vial to seal the HPLC Vial to ensure that there is no gap between the Cap and the Vial.Aijiren's Septa uses a double-sided material, and the combination of PTFE and Silicone makes Septa not easy to deform.

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)

• Self-sealing septa contain silicone that can interfere with LC/MS applications. • Single-layered septa are acceptable if they do not contain plastics or adhesives that can contaminate the sample manager (PTFE is recommended). 3. Use Aijiren Technology‐brand wellplates. Other brands can leach plasticizers (for example, diisooctyl

Use only HPLC-grade solvents and water filtered through 0.2 . µm filters. † Residues or contaminations may block filters or capillaries. † Label bottles correctly with bottle content, and filling date / expiry date. † Use solvent inlet filters to protect the system from incoming particles. †

Advanced Green inlet septa eliminate sticking and reduce coring. Bleed temperature optimized (BTO) inlet septa are preconditioned and ready to use with low-bleed, mass spec capillary columns. Our long-life septa are specially formed for extended use, meaning less downtime.

These HPLC and GC vials are available as snap, screw or crimp in style, 15uL to 20 mL in sample size, and various of low bleed and high-quality material composition. For GC, GC/MS applications where sample matrices contain volatile or semi-volatile analytes of interest, the most common choice are crimp style vials to limit sample contents from leaking from the vial/closure combination.

injection methods. PTFE septa are rarely used for GC applications. Polyethylene (PE) Septa and Integral Molded Closures Chemically resistant polyethylene septa are usually molded into single-piece caps. The surface for needle penetration is 0.01" thick, allowing for use with most HPLC autosamplers. Polyethylene septa are not resealable and are
