caps with septa

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. One-piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one-time use and reduce sample preparation time as there is no cap and seal to assemble.

Aijiren has produced 24mm Screw Neck Closures for more than 20 years. From Cap processing to Septa production, all are produced by fully automated machinery. Aijiren promises to use dust-free workshops to produce Screw Closures to ensure the cleanliness and high quality of the products.

The 20ml GC analysis headspace vials series strictly controls the HPLC vials mouth to improve the sealing performance. The precision molding bottleneck improves the processing capacity of the autosampler.

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. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.

Hole Caps are available in phenolic or polypropylene. Phenolic hole caps are provided without a septa. Polypropylene hole caps are available preassembled with separate septa or without septa. We also feature polypropylene hole closures with bonded septa to provide assurance that the septa will not slip away from the cap while injecting.

We provide the protection of PTFE and the resealing ability of silicone with our septa and seals to fit our autosampler crimp top vials. This seal includes a two sided PTFE septa with silicone in the center. 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 reduces the chance of contamination during sample preparation, while saving sample preparation time in the lab.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.
