Our 9 mm wide mouth vials and caps are our recommended screw bottles. These vials are compatible with autosamplers and have an opening 40% larger than 8-425 threaded vials, simplifying pipetting and other routine functions. Aijiren Tech provides 9mm clear glass bottles and amber glass bottles, as well as polymer options and qualified glass bottles.

Screw glass vials, also known as screw thread vials or screw top vials, are small containers made of glass that have a screw cap closure mechanism. These vials are commonly used in laboratories and other scientific settings for the storage and transportation of liquid or powdered samples.

Aijiren finds the right size filter in order to ensure that customers can filter the particles correctly. It is recommended that you choose the diameter of the filter carefully. Aijiren produces usually sizes of 13 mm and 25 mm. Each of them has a different ability to hold particles. According to the sample size, the appropriate filter diameter can be selected. For example, a diameter of 13 mm can be used for samples of 1-10 ml. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Aijiren has been producing 2ml glass autosampler vial since 2009. The glass vials we produce are widely used all over the world. For more than ten years, our customers are in more than 70 countries and regions. Our 2mlvial is also well received by customers. Aijiren’s customer service and product quality are among the best in laboratory consumables.

We provide septa and caps to fit our autosampler crimping the top vial to provide PTFE protection and silicone resealability. The cap includes a double-sided PTFE septum with silicone in the middle.

These caps form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Great for everything from liquids, to soaps, to macro-invertebrates.

The standard 11.6x32mm profile is compatible with 11mm aluminum seal closures
For closure selections please see Aluminum Seals.
Silanized glass vials are an excellent solution when protein absorption must be avoided. The silanization process deactivates charged SiOH sites on the glass surface, limiting the hydrophobic effect.

Caps are made of high quality polypropylene, Caps have the profile of a crimp or snap closure for compatibility with robotic autosamplers, Pre-assembled septa reduces the chance of contamination during sample preparation, while saving sample preparation time in the lab.

EPA sample bottles are used to store EPA reagents, enzymes and other diagnostic reagents, and biochemical reagents or samples. The screw is sealed to prevent leakage and can be used at low temperatures. Amber Storagr vials can be used for light-sensitive samples.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, top headspace vials meet high standards to meet your regulatory requirements.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.

Standard opening 12×32 viale
8-425 screwed vial is the original standard opening vial
Viars are manufactured in clear, type I class A or amber, type I class B borosicate glass
Viars have standard calibrated write patches to facilitate sample filling and identification
The use of 8-425 closures and 8mm septum is required.

Syringe filter is a small, disposable device that is commonly used in laboratory settings to filter or clarify fluids. It is designed to be attached to the end of a syringe and acts as a barrier that removes particles and contaminants from the fluid as it is forced through the filter.
Syringe filters typically consist of a plastic housing with a membrane filter inside. The housing has a female luer lock or luer slip connection that allows it to be securely attached to the syringe. The membrane filter, which is the key component, is made of a porous material that allows the fluid to pass through while retaining particles and contaminants above a certain size.

The hydrophobic PTFE syringe filter membrane is made of hydrophobic polytetrafluoroethylene. It filters organic solvents, aqueous solutions and gases that are chemically corrosive, and can withstand most strong acid and alkaline solutions. Product application: Used for the clarification and filtration of strong acids and alkalis, the filtration of high-temperature liquids and special chemical reagents, and the clarification and filtration of air or various gases.

All Aijiren vials are ideal for autosamplers and have excellent chemical compatibility and ultra-cleanliness. Crimp top sample vials are currently the most commonly used gas sampling vials on the market. Sample vial with a 2ml capacity that is particularly suitable for use in laboratories. At the same time, some vial bottoms are designed to be round bottoms, so the bottom is flat and compatible with automatic sampling equipment.

The 0.3ml micro-insert produced by Aijiren has a specification of 31*6mm and a flat bottom. It can be applied to Aijiren’s 2ml hplc vials. It is usually used for experiments when samples are scarce, or when samples are more precious.

Standard GC, HPLC sample vial, small caliber, 8-425 standard threaded mouth, can be used for autosampler and sample storage. It can be used with 8-425 screw cap septum.
8-425 Autosampler Vial, often used in conjunction with Shimadzu, Spectrophysics, Varian, and other autosamplers. The vial is made of colorless Class 1 Type A or Amber Class 1 Type B borosilicate glass , And attached with a writable label for sample identification.

Chromatography sample 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.

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.

Aijiren’s 20ml crimp top headspace vials have two types of round bottom and flat bottom. Please check the instrument you are using before buying. Is the round bottom or flat bottom headspace vial suitable? Aijiren designed the 20ml crimp top headspace vials in order to be more Accurately use with your instrument. 20ml crimp top headspace vial has a very good seal and can be used for volatile samples, but it needs to be used with 20mm Hand Crimper to seal the vials, and when opening the lid, it needs to be sealed with 20mm Hand Decrimper. You can refer to Aijiren’s product page to purchase the matching Hand Crimper/Decrimper.The caliber of the 20ml crimp top headspace is 20mm. Before buying, you need to check the specifications carefully to prevent it from being used after purchase.

The crimp vial produced by Aijiren has a standard 11.6x32mm shape and is compatible with 11mm aluminum sealing caps. The Aluminum Cap is 11mm in diameter and has a 5.5mm center hole, which is convenient for sampling with automatic injection needles. In addition, the Septa matched with crimp vial can also be pre-slit to facilitate the automatic injection needle to pierce the septa.
