Characteristics of PVDF Syringe Filters:
Hydrophilic
Low protein binding
Good chemical compatibility and low extractable
Superior mechanical resistance
Higher resistance to temperature

The nylon membrane of the syringe filter should be compatible with the chemical characteristics of the sample. The nylon membrane should be compatible with various water-based and organic solvents. The membrane should also have high resistance to HPLC solvents and chemicals. The 0.45mm aperture ensures that you have enough capacity and throughput to process samples efficiently and quickly.

Aijiren brand syringe filters are HPLC certified to ensure reliable and consistent results. Water, methanol, and acetonitrile are used for testing, and HPLC is used for detection at 210 and 254 nm wavelengths. None absorbs ultraviolet light, which can provide a purer analytical background.

You can choose a PTFE needle-punched filter to improve the filtration efficiency in any area. They provide high-performance filtration through an application-centric design and can be used in various industries that process organic samples.

Many different types of materials are used in syringe filters. A variety of materials, diameters, pore sizes, and in sterile and non-sterile options are on our list. These syringe filters offer outstanding microfiltration for applications in HPLC, water treatment, environmental, biotechnology, beverages, food, pharmaceuticals, and other fields related.

Aijiren headspace vials have clear or amber glass, round or flat bases, crimp seals with beveled or square edges, or screw seals. Headspace vials, septa and caps can be purchased separately or together as a convenience kit to meet the needs of your laboratory.

The vial cap corresponding to the 4ml screw vial combines innovation with time-saving convenience. The chemically inert bottle cap produced by this patented method truly combines the septum and the cap at the molecular level, which can avoid excessive evaporation and keep the sample bottle properly sealed. The thickness of the 13mm septum is 1.5mm, and the PTFE is about 0.1mm.

The optional capacity of the headspace bottle is 10ml 20ml, the specifications are: 22.5 * 46mm, 22.5 * 75.5mm, and colorless and brown headspace vials are provided. The 20ml GC analysis headspace sample bottle series strictly control the HPLC sample bottle mouth to improve the sealing performance. The precise molding bottleneck improves the processing capacity of the autosampler.

The snap-on sample vial is made of type 1 borosilicate glass (type A, 33 expanded borosilicate glass), transparent or amber, or made of polypropylene. The snap-on vial can accept either aluminum snap-on seals or polyethylene snap-on caps. Very suitable for short-term storage. You can also deactivate MS authentication.

Aijiren’s 2ml crimp top-level sample vials have strict quality assurance, consistent size from batch to batch, optional ceramic writing points with filling marks, and are certified to be fully compatible with autosamplers.

Snap Cap vials Wide-mouth vials are easy to fill and provide a larger target area for the autosampler needle. Suitable for most autosamplers, it can hold 12x32mm sample bottle format, high-quality 33 expanded borosilicate transparent glass type 1 (type A) or 51A amber glass uniform, flat bottom ensures that Vial can stand stably on the desktop.

The 20ml screw threaded headspace vial is used for the threaded vial (10ml + 20ml) and magnetic screw cap of CTC and TriPlus autosampler. It is easy to use and does not require any other tools. Samples can be transferred on site, without the need to transfer samples in the laboratory. The precise thread ensures the air tightness between the vial and the cap. Magnetic nut can be widely used in various SPME and headspace analysis. The round bottom vial is stronger, has higher pressure resistance when heating the sample vial, and is easier to slide into the heating hole.

Aijiren’s advantages of crimping top-quality sample vials, PTFE/silicone/PTFE septa has excellent core resistance, compatible with a variety of autosamplers, years of experience and good quality control, including vial height, diameter, bottom, and thickness And neck/thread, cleanliness.

Snap ring closures N11 should only be used in HPLC, as the punctual compacting pressure of the septum against the vial rim by the four pins in the cap does not achieve the same level of tightness as the evenly applied pressure through a screw thread or by crimping.

Snap Top vials are made of high-quality, GC-tested materials and are suitable for most chromatographic applications. In some applications, Aijiren 11mm bayonet vials provide an economical alternative for users of chromatography consumables.
