A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

The vial has an outer diameter of 8mm, which is a common size for HPLC autosampler systems. This standard size ensures compatibility with a wide range of autosamplers and other accessories. These vials are typically made from high-quality, Borosilicate Glass or 1st hydrolytic-class glass to prevent interactions between the sample and the container. 2ml Autosampler Vials 8-425 neck finish represents HPLC vials &gc vials, the vials a diameter of 8 mm across the outside of the threads and a thread style of 425, Vials has clear and amber, Screw Cap in Lab most of the 2ml vials are 12*32mm. Aijiren screw thread top sample vial design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial.

Aijiren polypropylene snap micro vials can be used in most standard gas and liquid chromatography autosamplers. These lightweight, economical vials are made from durable polypropylene which has good chemical resistance. The conical interior ensures maximum retrieval of contents without the hassle of using removable inserts. A body size of 12*32mm makes it compatible with most autosamplers such as Agilent, Varian, etc. Snap/crimp top compatible with caps that are used with 11mm snap ring vial and crimp neck vial ND11. PP Micro Vial with one of our seals can be obtained as a 2in1 KIT Special Push-On Cap with a thinner penetration point made of Polyethylene for Snap Ring Vials and Crimp Neck Vials ND11.

The 11mm snap-top caps are made of high-quality polypropylene. The caps have a roll-edge or snap-on shape. The snap-top caps provide a secure seal that minimizes evaporation even for volatile samples. PTFE/silicone septa are the product of choice for most HPLC and GC applications where resealability and high purity are critical. Ideal for applications where ease of needle insertion is important. Silicone septa have strong re-sealing properties and can still maintain good sealing performance after multiple injections; PTFE is currently a material with good chemical conditions and can withstand strong acids and alkalis. After the two materials are combined, the bottle can be used for various laboratory purposes such as sealed sampling and chemical storage.

Aijiren offers innovative high-recovery vials for comprehensive collection, automated handling, and storage, with the subsequent maximum retrieval of high-value samples. High recovery vials offer precision vials made from low expansion borosilicate glass and are designed with a unique interior bottom, solid glass bottom of a Microliter-Vial with an inner cone, allowing for maximum retrieval of contents by a syringe. High Recovery Vials Reduce Residual Product Waste by 99%. high recovery vials are optimal for manual and automated compound or biological sample applications.

The cap is made of aluminum. Aluminum is commonly used due to its excellent sealing properties and resistance to corrosion. The septa is a critical component of the cap and is made of silicone or PTFE (polytetrafluoroethylene).  It is positioned inside the cap and serves as a barrier between the sample and the external environment. The cap has a crimp top design, which means it can be securely attached to the vial by using a crimping tool. This process involves crimping the cap around the vial’s neck, creating a tight and tamper-evident seal. These caps with septa provide an effective barrier against contamination, evaporation, and changes in sample composition, ensuring that the sample remains stable and reliable for analysis.

In your experiment, No matter what questions was happened, you can tell our techincal engineer. They will give you solutions. Welcome to inquiry.

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. Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process.
The adhesive-free bonding process is used to combine the polytetrafluoroethylene membrane and the silicon rubber or silicone bond together to maintain the excellent characteristics of the two materials. The polytetrafluoroethylene layer of the composite septum is in contact with the reagent. It is chemically inert and resistant to acid, alkali, temperature, and adhesion. It does not work with concentrated acid, concentrated alkali, or strong oxidants even at high temperatures. At the same time, the elasticity of silicone rubber or silicone layer can ensure sealing performance.

The 2ml HPLC Screw Vials are made from clear/ amber, Type I borosilicate and 33 expansion glass.2ml Amber HPLC Screw Vials with unique thread design ensures consistent seal and can be reused, not volatile, easy to use, Reduce the chances of bent or broken needles during sampling.

11mm crimp top autosampler vials are suitable for Agilent, AB Sciex, Brukers, Techcomp, PerkinElmer, ThermoScientifics, Shimadzu, Waters, CTC autosampler and other rotating or robotic arm samplers and autosamplers.

All 2ml HPLC Vials may appear to be created equal, but quality and performance make the difference when analyzing vital samples. Aijiren as a leading manufacturer in China, supplies high-quality chromatography consumables such as 2ml HPLC Vials with Cap and syringe filters.

Polypropylene vials are an economical alternative to glass for some applications. The vial is primarily constructed from high-quality, durable polypropylene or polymethyl pentene (PMP). This plastic is typically chosen for its chemical resistance, inertness, and transparency. Polypropylene is the most popular plastic material. Polypropylene vials have heat resistance of up to 135 degrees Celsius and are commonly used in chromatographic experiments. PMP has higher heat resistance – up to 175 degrees Celsius – and is transparent, increasing the sample’s visibility inside the sample bottle. The vial typically has a standard 9mm outer diameter, making it compatible with a wide range of autosampler systems commonly used in laboratories.
