2ml snap autosampler vial is widely used in HPLC applications and can be used almost as universal sample vials for autosamplers, including sample vials with automatic operation. 

polypropylene snap/crimp micro vials combine the robustness of TPX PMP with the benefits of PP micro inserts.PP vial material was used for Ion analysis to avoid contamination by glass HPLC vials during analysis. polypropylene snap/crimp 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. Breakage is not an issue with plastic vials, and they are non-reactive with most sample chemistries. PP vials are ideal for samples where glass is not appropriate; as with samples that adhere to glass.

The size of Snap Vial is 2 mL, 12 x 32 mm, 11mm amber wide-mouth bayonet glass sample bottle using first-grade hydrolyzed glass as raw material. Standard sample bottles for GC and HPLC can be used for autosampler and sample storage.

Preassembled polypropylene snap-top closures with a 6mm center hole, including  PTFE/silicone septa. To use with 11mm snap-top vials. Snap caps provide a secure seal, minimizing evaporation even with volatile samples. Snap ring closures N11 should only be used in HPLC, as the punctual compacting pressure of the septum against the vial rim by the four pins in the cap does not achieve the same level of tightness as the evenly applied pressure through a screw thread or by crimping.

11mm Crimp Top Autosampler Vial for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials, manufactured of Clear or Amber borosilicate glass. The standard 12x32mm profile is compatible with 11mm aluminum seal closures. The precision-shaped bottleneck can improve the processing capacity of the autosampler. In order to ensure good function, it can be slit in advance to facilitate needle penetration, designed for single injection or short sampling cycle, and especially suitable for liquid chromatography. 

The Aijiren sample vial has excellent sealing performance, which can effectively avoid sample evaporation. The vial and the corresponding 11 mm aluminum cap can be easily and quickly combined with the jaw capping tool. The vial can withstand heat and pressure, and can also be used for chemical reactions. Especially for vials with white open caps and thick PTFE / silicone septa, they can be used as anhydrous and oxygen-free reaction vials.

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. 

Aijiren clear glass vial inserts, polypropylene vial inserts, and high recovery vials ensure you extract the maximum possible amount of your precious sample.

The hand crimping tool is easy and comfortable to use. The flare pressure limitation is adjustable by means of an adjusting screw in the handle. Due to their chemically resistant surface coating, the pliers are specially designed for use in the laboratory.

Micro Insert is used to ensure the most accurate and reliable analysis of your lab samples. Micro-inserts are manufactured of clear glass. 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.
Micro inserts can be used with screw tops, crimp tops, or snap-top vials. All conical styles of inserts are offered with the traditional pulled point as well as the improved mandrel point. Pulled point inserts are more economical, but mandrel point inserts provide a more pointed and uniform tip that enables better sample recovery. Micro-inserts can be used on all 1.5ml vials. Effectively relieves the pressure of the syringe. PolySpring inserts are self-aligning.

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.
