18mm screw top headspace vial with 10mm center hole metal screw cap

2ml Crimp HPLC Vial requires a relatively inexpensive painted aluminum crimp cap. When properly assembled, it will become the best seal for long-term storage. 2ml Crimp HPLC Vial with Cap needs to be used with crimper and cap opener. The crimp cap cannot be reused, it can only be used once.

Suitable for: 24-400 Screw Neck Vials, 20-60ml EPA VOA TOC Vials
Caps Material: PP
Cap Diameter: 24mm
Caps with Closed-top or with 15mm center hole
Septa Material: Nature PTFE / Nature Silicone
Septa Size: 22*3mm Low Bleeding

There are many differences between butly rubber and natural rubber. The main advantage is that butyl rubber has better chemical stability and aging resistance than natural rubber. It has the elasticity of natural rubber and contains no protein components, but not butyl. Chemical Stability and Aging Resistance

HPLC vials are specially designed containers used to hold samples for injection into an HPLC instrument for analysis. These vials are made of high-quality materials such as borosilicate glass or plastic that are chemically inert and have minimal interaction with the sample.

Aijiren Sample Storage Vial is usually used for environmental analysis. Clear Glass Vial can better see the state of the sample. Amber Glass Vial can withstand ultraviolet light and protect the chemical components in the sample that are sensitive to ultraviolet light.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Chromatography vial is a glass vial used by automatic samplers and headspace samplers such as liquid chromatography, gas chromatography, mass spectrometry, etc. for chromatographic automatic sampling. Its basic requirements are accurate volume, ability to withstand a certain pressure, good sealing performance, and no adsorption to samples.

PTFE/silicone septa are most commonly used in HPLC applications, and pre-cut septa are easier to pierce with a needle. The cap color is generally black, but other special colors can also be produced accordingly. Easy to apply and easy to remove. Pre-installed caps and septa are very convenient. Aijiren 13mm Screw Closures are commonly used in 4ml Screw Top HPLC Vial. Aijiren can recommend the most suitable Closures for your HPLC Vial.

Use Aijiren 11 mm Glass Crimp Top Vials with aluminum crimp seal closures. These high-quality 11 mm glass vials are 2 mL, 12 x 32 mm and fit most brands of autosamplers. Made of superior quality 33 expansion borosilicate clear (Type 1, Class A), they meet all requirements of US, EU, JPN Pharmacopia. Choose from Aijiren brands.

Aijiren has produced 24mm Screw Neck Closures for more than 20 years. From Cap processing to Septa production, all are produced by fully automated machinery. Aijiren promises to use dust-free workshops to produce Screw Closures to ensure the cleanliness and high quality of the products.

Micro inserts, when used in conjunction with autosampler vials, allow for maximum sample recovery and easier sample removal because the conical shape decreases the surface area inside the vial.

The storage vials are compatible with various laboratory storage methods, including refrigeration and freeze-drying. They can withstand a wide range of temperatures, allowing for long-term storage of samples under different conditions. The PTFE cap provides chemical resistance and ensures a tight seal, even during extreme temperature fluctuatio

The 4ml screw neck glass vial produced by Aijiren is often used in Autosampler. The 4ml 13mm opening is convenient for automatic injection needle injection. The Cap has a center hole. PTFE and Silicone are compounded on both sides to ensure that one side of PTFE faces the reagent inside Vias, ensuring that the stability of the reagent is not destroyed.

Snap seal vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp and/or snap seals and no special tools are required to remove the cap. These vials are recommended for short term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

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.

The 8-425 Aijiren 2ml autosampler vial is 12* 32mm wider than normal vial openings, so autosampler syringes can drill holes in the autosampler vial smoothly without error. 8-425 2ml autosampler vial neck PerkinElmer autosampler and other rotations or suitable for robotic arm samplers.

Aijiren’s 13mm Screw Vial is paired with quality PP Screw Caps, especially 13mm screw caps. The special angular design makes it very different from other pp caps. This is Aijiren’s new design product recently. If you are interested, you can Contact Aijiren.

Aijiren Headspace Vials feature rounded shoulders and bottoms, allowing for even heating and safer operation at higher pressures. The newly designed top provides a tighter seal with your septa. Vials are manufactured from Type I borosilicate glass and accept 20 mm aluminum seals.
