This article will teach you how to choose the best cap for your chromatography vials while taking into account things like chemical compatibility, sample integrity, sealing qualities, and considerations for temperature and pressure. You will be able to make judgments that will improve your sample quality and reliability in chromatographic analysis by adhering to this thorough instruction.

Vial caps play a crucial role in guarding the sample from spills, contamination, and evaporation. Ideally, caps should form an airtight seal and be inert. Caps may come with a silicone or polytetrafluoroethylene (PTFE) septum, which creates a tight seal. Needles can pierce the septum because the elasticity of the material allows it to reclose.

The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument downtime. Don’t let the complexities of septa selection slow you down.

The 2ml 9-425 autosampler vial with 11.6mm x 32mm size, and 9-425 9mm screw top, We performs rigorous testing of dimensions such as polishing, OD and length – to ensure that each vial is exactly matched to the autosampler jaws and injection system (DIN/ISO Standard), all dimensions are strictly subject to trouble-free operation, the vials can ensure running smoothly in the autosampler.

2ml autosampler vials with 9-425 threaded screw cap, 9mm blue PP bottle cap and pre-opened natural PTFE with seamless white silicone compartment to match sample bottle. The sample bottle is made of transparent Class A borosilica glass with a writeable label for sample identification. These sample bottle caps are 9 mm in size, 11.6 mm in diameter, 32 mm in height and 2 ml in size 100 packs.

Septa, caps and liners play a key role in the storage and preparation of samples. They securely seal samples from the external environment while simultaneously allowing injection by sampling needles. Aijiren cap septa offers new septum materials and unique processes to improve septum sealing integrity and reduce the risk of sample contamination.

Aijiren Tech 2mL 9mm Screw Thread Vials are constructed from from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching..9mm Vial is screw thread vials with a 9-425 GPI thread and the closure is dimensionally equivalent to 11mm crimp cap vials. This means that they can be used in any autosampler that uses 11mm crimp cap vials.
