Aijiren 9mm hplc vials are the preferred choice for modern autosamplers. With a focus on improved sample security and integrity, we now offer innovative 9mm closures and 9mm screw top vials. Standard opening screw-thread vials are manufactured from borosilicate glass and have a maximum fill volume of 2 ml for consistent productivity on every separation.

8-425 2ml Autosampler Vials from Aijiren is 12*32mm,It is 40% wider than the ordinary vial opening, thus ensuring that the syringe of the autosampler can pierce the bottle smoothly without errors. 8-425 2ml autosampler vials neck Suitable for Shimadzu autosampler and other rotating or robotic arm samplers.

Aijiren produces 2ml autosampler vial, headspace vial, sample storage vial, etc., in two colors, clear and amber. Amber has a light-shielding function, which can isolate ultraviolet rays and protect samples. Aijiren is made of high-quality borosilicate hydrochloric acid glass, the cap is made of polypropylene, and the septa is made of silicone and ptfe to ensure the sealing and quality of the vial.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Our Headspace Vial features a user-friendly design with a labeling area for easy sample identification and traceability. This enables efficient record-keeping and organization in your laboratory, ensuring accurate tracking and retrieval of crucial analytical information.

specification:
It can also be used in cosmetic liquids, essential oils, etc.
All bottle caps have screw-in black polypropylene caps.
Easy to carry, easy to place in the family.
With screw cover, it is well sealed to avoid leakage.
Used to store small amounts of chemical solutions and fumes

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.

A 20ml EPA Amber screw vial is a type of laboratory container commonly used for the storage and transport of samples in environmental analysis。
The 20ml EPA Amber screw vial is commonly used in environmental analysis for the storage and transportation of water, soil, or air samples.
It is suitable for various analytical techniques, including gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS).

The 20mm Caps with Septa are specifically designed for secure sealing and precise analysis of headspace samples in laboratory settings. These caps have a 20mm diameter, ensuring a tight and reliable fit on crimp headspace vials. The septa, made of high-quality materials, provide excellent sample integrity by preventing contamination and evaporation during storage and analysis.

Aijiren’s septa for 24mm screw closures uses natural-color Silicone and PTFE. These Septas have a diameter of 22mm and a thickness of 3mm, which are consistent with the size of the Cap and can be placed between the Vial and the Cap to isolate the air and the sample. The size is 3mm. The thickness is also very suitable for needle piercing. The material of Septa is soft and tough, not easily deformed and will not break.

20mm Crimp-top Aluminum Rubber Septa typically refers to a type of closure system used in laboratory settings. It consists of an aluminum cap combined with a rubber septa.
The aluminum cap is designed to seal the opening of a container, such as a vial or bottle, and is typically made of aluminum or aluminum alloy.
It provides a secure closure to prevent leakage, contamination, or evaporation of the contents.
The aluminum cap ensures a secure fit, while the rubber septa provide a barrier against leaks, contamination, and sample evaporation.

Aijiren sample vials have excellent sealing performance, which can effectively avoid sample evaporation. The sample bottle and corresponding 11 mm aluminum cap can be easily combined with the crimp cap tool. The vial can withstand heat and pressure, and can also be used for chemical reactions. Especially for sample bottles with white open caps and thick PTFE/silicone septa, they can be used as anhydrous and oxygen-free reaction bottles.

Aijiren’s Snap Top 2ml HPLC Vials for autosampler are constructed from type 33 and type 51 COE borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching.
By choosing Aijiren caps and septa, you provide your sample with a the best containment solution available.

With its 9mm screw thread design and capacity of 1.5mL, this vial makes for easy handling and integration into autosamplers. Ideal for applications requiring limited quantities. The vial comes equipped with various finishes and closure options, such as screw caps and snap caps, so researchers can select their ideal choice according to their unique research needs.

The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.

Aijiren not only produces autosampler vial, but also accessories for autosampler vial. Cap with Septa, especially the production of Cap, needs to be exactly the same as Autosampler Vial. It must also produce different types of Cap with different necks. Aijiren is a high-quality company. Chromatography consumable manufacturers, there is no error between the PP Cap produced, and it can perfectly match Autosampler Vials

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. Crimp closures N11 are also universally suitable with regard to autosampler compatibility.

Polypropylene Screw Micro Vials can be used in most standard gas and liquid chromatography autosamplers. These lightweight, economical vials are made of durable polypropylene with good chemical resistance. The conical interior ensures maximum recovery of contents without the hassle of removable inserts.

COD testing is a good better indicator of organic pollutants in industrial wastewater containing cyanides and heavy metals. COD testing affords rapid response to changing conditions before critical problems develop.

Micro inserts can be used with screw tops, crimp tops, or snap top vials. Seal these vials with 9 mm/10mm screw caps or 11 mm crimp/snap caps and the corresponding septa depending upon which vial type you use.
