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.
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 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.
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.
Aluminum crimp-top cap, 5.5mm center hole, 11mm diameter, with pre-slit white PTFE/red silicone septa, 100/pk. Aijiren 11mm Crimp Top Caps with Septa can squeeze the septa between the rim of the crimp vials and the folded aluminum cap. The crimp cap has a good sealing effect and can effectively prevent the sample from evaporating. In addition, this type of bottle cap can keep the position of the septum unchanged when the autosampler is used for puncture sampling of the sample. High quality and performance, the septa and cap for crimp top sample vials are welcomed by more and more clients around the world.
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.
The Crimp Top Chromatography Vial is the most commonly used gas sampling vial on the market at present. Features of crimping top-quality sample bottles: Strict quality assurance provides dimensional consistency between batches, optional ceramic writing points with filling marks can be selected, and they are certified and fully compatible with autosamplers.
