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.
All materials are produced at 100,000 grade clean room. Passed ISO9001:2015 quality management system certification, RoHS compliance can also be provided.
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.
Crimp caps squeeze the membrane between the edge of the glass bottle and the crimped aluminum cap. This creates a good seal and prevents evaporation. Crimp cap vials require a hand crimper tool to perform the sealing process.
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.
A 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. The vial features an 11mm snap ring closure, which provides a secure and leak-proof seal. These 2ml snap autosampler 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. Vials have a 40% larger opening than standard aluminum seal vials for easier sample filling and to reduce the chance of bent or broken needles during sampling. Compared with crimp top vials, snap vials can be capped and uncapped easily without tools, making it more convenient to use.
The 11mm crimp top autosampler vial 2ml is the most commonly used gas sampling vial on the market at present. The 11mm crimp top vials are the best option for customers concerned with evaporation of their volatile samples, as the crimp seal significantly reduces the opportunity for evaporation. 2 mL crimp top vials are manufactured from type 1 borosilicate glass. The high-quality material has very low metal content to help avoid sample deterioration or leaching. Precisely shaped bottlenecks increase autosampler throughput. Made of PTFE/silicone fusion, this septum has excellent inertness and can be used for multiple injections.
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 reduce the chance of contamination during sample preparation while saving sample preparation time in the lab. Snap caps provide a secure seal, minimizing evaporation even with volatile samples, The audible click ensures that a secure seal has been formed and the cap is properly applied.
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. The vial features an 11mm snap ring closure, which provides a secure and leak-proof seal. Snap ring closures are easy to use and ensure that the vial remains tightly sealed during sample storage and analysis. 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.
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 2 mL crimp top vials are our recommended vials for gas chromatography applications. The crimp top vials are the best option for customers concerned with evaporation of their volatile samples, as the crimp seal significantly reduces the opportunity for evaporation. Crimp vials are also used for samples in which chain-of-custody or tamper-proof closures are required. 2 mL crimp top vials are manufactured from type 1 borosilicate glass. The high-quality material has very low metal content to help avoid sample deterioration or leaching. Precisely shaped bottlenecks increase autosampler throughput. Made of PTFE/silicone fusion, this septum has excellent inertness and can be used for multiple injections.
Standard Autosampler Vial for HPLC & GC Chromatography, vials can be used for high-performance liquid chromatography and gas chromatography for reliable analysis results Material: Glass Color: Clear Height (Metric): 32mm Outside Diameter (Metric): 12mm Patched: No Residual Volume: <170uL Quantity: 100Pieces/Pack
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.
Aijiren 2ml snap neck has 40% lager target area which makes it much safer for the autosampler needle. Snap vials can be closed with either snap caps or crimp caps. Snap cap vials cannot be pressurized, but can be easy as push-on, pull-off by hand. A audible click ensures a secure seal has been formed and that the cap is correctly aligned. Precision-formed neck improves autosampler handling.
1mm snap autosampler vial often used in conjunction with Shimadzu, Spectrophysics, Varian and other automatic samplers, the bottle is made of colorless type 1 A or amber type 1 B borosilicate glass It is completed with a writable label for sample identification.
