Aijiren’s Magnetic Precision Screw Metal Cap is 18mm in size, which is very suitable for sealing gas chromatography. This kind of cap is often used in headspace vials, and the center hole with it is very convenient for sampling by autosampler.
The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Glass Screw Top Autosampler Vials, the product material is of paramount importance.
The crimp vials produced by Aijiren are made of transparent or amber type 1 borosilicate glass or polypropylene. Requires crimper and lid opener. Very suitable for long-term storage. Deactivation and MS authentication can also be used.
The butyl septa on the PTFE surface can be used in the headspace sample bottle to evaluate the injection activity and the penetration efficiency of methyl bromide on the activated carbon. The septum can be used to seal the vial during liquid sample collection for unmodified benzene analysis using HPLC method
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.
The 9mm hplc vials produced by Aijiren can be used in many places and scenarios. The GC System is just one of them. More often, the 9mm hplc vials produced by Aijiren are used in different Autosamplers. Its compatibility is a major part of its popularity. the reason. Aijiren’s 9mm hplc vials is one of the most popular products.
In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.
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.
Although Aijiren has attractive prices, the focus is still on quality. The membrane materials are provided by the most famous people in the industry, and in the ISO9000 certified production process, the latest manufacturing technology is used, and the production is carried out under the highest standard under certified clean room conditions to ensure high quality and stable products. . All syringe filters are HPLC certified.
9mm screw thread caps, septa, and vials are designed especially for use with Aijiren’s and other rotating or robotic are samplers
2ml 12*32mm clear borosilicate glass vial,with a write-in patch; high quality polypropylene caps, ptfe / silicone septa can be pre-slit to easy needle penetration
2ml Snap Top HPLC Vial is made of Type 1 borosilicate glass. Comparing with 9mm screw vial, this 2ml Snap Top HPLC Vial mouth is wider opening. So 2ml Snap Top HPLC Vial is easier to fill and provides a larger target area for the autosampler needle. That means, the 2ml Snap Top HPLC Vial can protect the needle.
Aijiren is a manufacturer specializing in 6ml 20mm Crimp-Top Headspace Vial. Aijiren’s customers are located in more than 70 countries around the world. Aijiren has created the title of China’s well-known 6ml 20mm Crimp-Top Headspace Vial supplier with service and product quality.
Another way to determine the micron size of columns, 0.45 um for >3 um, and 0.22 um for <3um. 0.45 um membranes are typically used for general filtration and particle removal while 0.2/0.22um membranes, or sterilizing-grade membranes, are most commonly used for solution sterilization (bacteria removal).
Reagent bottle also called media bottle, widely used in laboratory
Material: Borosilicate Glass
Cap type: GL32 Screw Cap
The glass media bottle is made of borosilicate glass or soda lime glass and equipped with a plug or cover to prevent the contents from overflowing or being polluted by the external environment. Reagent bottles are ideal for storing powders and liquids. Amber or red media bottles can protect photosensitive contents from ultraviolet, visible and infrared radiation.
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
“Aijiren Vials manufactured of Clear, Type 1 Class A or Amber, Type 1 Class B, borosilicate glass
Aijiren Vials have a standard graduated write-on patch for easy filling and identification
Snap caps used with the Aijiren Vial system are a convenient alternative to aluminum seals
Snap caps or aluminum seals ensure a secure seal for samples”
2ml 9mm Screw Top Autosampler Vials are cleaned and packaged in a certified Class 10,000 clean room according to a designed process, developed to eliminate chromatographic errors associated with vials. For Chromatography vials, 2ml 9mm Screw Top Autosampler Vials is the most commonly vial in laboratories. 2ml 9mm Screw Top Autosampler Vials are more leak-tight and easy for the experimenter to operate.
A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples. Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even sterilization.
Headspace Crimpe Vials are available in volumes from 6 mL to 20 mL. We offer Headspace Crimpe Vials with a flat top or a beveled top, and are available with either a flat bottom or a rounded bottom Headspace Crimpe Vials for your application.

with pre-slit septa white silicone blue PTFE
The optional capacity is 10ml 20ml and the specifications are 22.5 x 46mm, 22.5 x 75.5mm, providing both colorless and brown headspace vial. The 20ml GC Analysis Headspace Vial Series strictly controls the HPLC vial mouth to improve sealing performance. Precision molding bottlenecks increase the processing power of autosamplers.
The Sterile syringe filter produced by Aijiren is a single-use membrane-based filtration facility that is mostly used to remove particulate impurities from liquid and gas samples before analysis by HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing methods. . Correctly filtering samples in chromatographic experiments can improve the quality and consistency of analysis results and reduce instrument downtime. The sterile syringe filter adopts high-temperature aseptic processing and vacuum packaging of liquid to ensure the cleanliness of the syringe filter. It is recommended to be used once.
Headspace vial is made of transparent or scarlet glass and is available on round or flat bases, crimp seals with bevel or square edge finishes, or thread finishes. Headspace viars, septaums, and caps can be purchased individually or collectively in different quantities as a convenient kit to meet the needs of the lab.
If your sample is sensitive to light, use amber vials. If you need to view a color change then a clear Screw Top HPLC Chromatography Vials are the best choice. The Screw Top Headspace Vials are manufactured from Type I borosilicate glass.
