8mm 1.5ml Screw Neck HPLC Autosampler Vial

Due to the large amount of glass used in the vial neck, the snap seal vial is hard to break when the cap is removed. The neck finish of the snap seal is compatible with crimps and/or snap seals and does not require any special tools to remove the cap. These viars are recommended for short-term sample storage and non-volatile samples because seals are not as secure as crimp or thread seals.

Aijiren vials are very suitable for autosamplers and have good chemical compatibility and ultra-cleanliness. The crimping top sample bottle is currently the most commonly used gas sampling bottle on the market because of its very good sealing. The sample bottle with a volume of 2ml is especially suitable for laboratory use. It also has a flat bottom function and is compatible with automatic sampling equipment.

The 2ml Snap Vial provided by Aijiren is suitable for use on Waters Autosampler. The bayonet design of Snap makes the operation of capping Vial very convenient. Aijiren’s Snap Top Vial Cap is made of high-quality PP plastic, and can be customized in a variety of colors to meet customer needs.

20ml crimp top headspace vial is a type of vial commonly used in gas chromatography (GC) systems for analysis of volatile and semi-volatile compounds. It is specifically designed for headspace sampling, which involves extracting the volatile compounds from a solid or liquid sample into the gas phase for analysis.It’s important to note that the specific details and requirements of using a crimp top headspace vial can vary depending on the GC system and the analysis being performed.

1. Septa and slit septa are available. 2. The usually available cap color is silver, and other special colors can also be produced accordingly. 3. Easy to apply and easy to remove. 4. Aluminum sealing ring with pre-inserted septum is compatible with standard opening crimp top vials.

Aijiren’s syringe filters with nylon membranes are compatible with a wide range of solvents, making them ideal for fast filtration of most aqueous and organic solutions. Therefore, when a mixture of sample aqueous solution and organic solvent passes through nylon membrane, fine droplets of extractor solvent accumulate and are separated from the sample aqueous solution. Using this simple method, the total extraction time is only 3-4 minutes; It is environmentally friendly, has no centrifugal effect, provides a higher sample purification rate by filtering receptor phases, and filtering reagents ensures reduced impurities and protects the color column.

Aijiren 18mm magnetic screw cap (silver) and silicone/PTFE septa. Cap: The magnetic 18 mm screw cap can be effectively tested on the gas chromatograph autosampler, and the standard aperture of the center hole ensures the effective injection of the autosampler. Septa uses inert PTFE and Silicone bonding, or PTFE and Butyl bonding, these can be provided to customers to choose.

8-425 thread caps and viars are often used in combination with Shimadzu, Specra-Physics, Varian, and other autosamplers
The vial is made of transparent type 1 class A or amber, type 1 class B borosicate glass and contains writing patches for sample identification.

9mm Amber glass vials are perfect for storing samples that are sensitive to light exposure. 9mm Clear glass vials are great for testing the solubility or dispersability of materials, allowing you an unhindered view of the solution. Our vials come in 2 ml, along with 100 caps lined with septa.

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.

Screw-top Vials and caps are easy to use and require no special tools. The unique thread design provides a consistently secure seal, preventing evaporation. Screw Thread Vials are available in 8-425 (8mm) neck finishes.

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

The China 18mm 10ml Screw Headspace Vial Supply is compatible with various headspace sampling techniques and instruments commonly used in the laboratory, such as gas chromatography (GC). The 10ml capacity of these vials is ideal for accommodating moderate sample volumes, facilitating efficient analysis while minimizing the need for frequent sample preparation. The screw top design allows for easy sealing and unsealing, enhancing convenience and workflow efficiency.

Aijiren’s sample storage vials are produced by fully automated machinery. This production method is efficient and consistent in specifications, and it is not easy to make errors. The packaging is a PP box, 100pcs is a box for packaging, the customer should purchase according to the box when purchasing, the minimum order quantity of Aijiren is 10 boxes.

The 18mm Screw Headspace with caps with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace with caps with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm headspace vial with cap is preferred for the following instruments: Shimadzu.
How to choose whether to buy the Headspace Vial with round bottom or flat bottom? The round bottom is stronger, so it is more resistant to the high pressure in the sample Vial during heating. In addition, the vial is easier to slide into the heating block when transported by the magnet. When the vial must run in the instrument with a slight downward trend, a flat bottom may be required.Select the correct Headspace Vial at the bottom and use modern instruments to prepare the entire experiment with highly repeatable samples for accurate analysis.

Crimping headspace bottles are mostly used for liquids and powders that need to be sealed. The colors are mostly transparent colorless glass, amber glass, and silver open-hole aluminum cap.

Suitable for 11mm 2ml Crimp Neck Vials & 20mm Headspace GC Vials
Caps Material: Aluminum
Use Together with PTFE/Silicone Septa or Rubber Stopper
Color: Metal Silver
Vial Septa & Rubber Stopper and Crimpers are also Provided

Chromatography septas can be pre-slit or not and must be considered by evaluating a few factors. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided.

Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications.  Screw Glass vial for autosampler instrument is made of borosilicate glass. Different vial mouth designs meet different actual needs. 

Whether used in pharmaceutical research, biotechnology, or other laboratory settings, the 15-425 Screw Sample Storage Vial offers a reliable solution for sample storage and organization.
