Features. Aijiren 12 mm vial racks are ideal for holding 2 mL glass vials ( 2 ml screw vials, 2 mL crimp vials or 2 mL snap vials) for table top sample prep. Vial storage boxes are able to hold 50 x 2 mL vials instead which offer a cover when compared to an open vial rack. Return to top.

Aijiren's 2 mL screw top vials are constructed from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. Our 2 mL glass vials are available in both amber and clear versions. The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone

mixtures. Polypropylene septa offer better solvent compatibility compared to polyethylene, but piercing force is slightly higher. Viton (V1) septa Viton septa are used in situations where a resealable septum is required for a sample matrix that aggressively attacks all other materials. Viton offers chemical resistance similar to PTFE along with

Septa materials & properties. Septa are made from different materials. See below for definitions and uses of different types of septa materials. Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness.

PTFE, PFA and Teflon Bags Modified PTFE is a Fluoropolymer film that is an excellent choice for heat sealing applications that require extreme chemical and high temperature resistance. MPTFE is also a cost effective alternative when compared to FEP and PFA.

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]

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 intended for single injection use with aqueous based sample mixtures. Polypropylene (PP) Septa and Integral Molded Closures

Made of Type I Borosilicate glass, providing exceptional resistance to heat shock and chemical leaching. The glass is non-porous and has no catalytic affect.

-40 °C -60 °C natural rubber/TEF natural rubber/TEF; butyl/PTFE red rubber/ PTFE silicone/ PTFE Thin, fragile needle? Soft and thin septa required e.g. silicone/ PTFE Blunt, thick needle? Slit/pre- cut liner as penetration aid (HPLC) silicone/ PTFE, slit Critical analysis? Very clean liner required

Aijiren's headspace vial caps are engineered to prevent sample contamination while providing consistent, secure seals. Headspace vial caps are available in a variety of materials including aluminum, bimetal, and steel; headspace vial cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature varieties.

Septa and liners can be laminated with PTFE on one or both sides to provide high chemical resistance and a nearly inert barrier between sample and septa material. If you’re working with sample and media storage containers made of glass and plastic, the most common closure liner materials/styles for screw caps that we recommend includes poly
