The Aijiren 15x45mm vials have a 13-425 GPI thread and can hold up to 4ml of sample. Use the 13 x 425 caps with septa for use as sample vials and with diffusion caps for wash vials. With closed top screw seals, these vials can also be used as storage vials.

Polypropylene/PTFE silicone screw vial caps with septa are commonly used in high-performance liquid chromatography (HPLC) and other analytical techniques.These caps provide a secure seal for vials, preventing sample evaporation and contamination.When selecting polypropylene/PTFE silicone screw vial caps with septa, consider factors such as thread compatibility with your vials, the specific requirements of your HPLC system, and the chemical compatibility with your samples and solvents. Reputable manufacturers and suppliers offer a range of options to suit different vial sizes and analytical needs.

The automatic vial is made of high quality raw materials. It has high temperature resistance and corrosion resistance. The septum of the autosample vials is made of high quality materials to ensure proper functioning and is widely used in multiple injection or longer injection cycle designs as well as gas and liquid chromatographs.

The 13-425 4ml Screw Vial offers several key features and benefits. Its high quality glass construction ensures chemical resistance and maintains sample integrity during storage and analysis. The screw cap design provides a tight seal, preventing leakage and minimizing the risk of contamination. The vial’s transparency allows for easy visualization of samples, improving accuracy and efficiency. It is widely used in various applications including chromatography, pharmaceutical analysis, environmental testing and more.

The 4ml 13mm Screw Thread Vials often feature clear graduated markings on the side, allowing for accurate measurement and dispensing of samples. These graduations provide researchers with a visual reference for precise volume control, minimizing errors in sample preparation and analysis.

4 mL screw top vials, also called waste vial or wash vial, usually used to wash the needle of autosamplers. Our 4ml Vials are manufactured from Type I Borosilicate Glass, which meets all USP, JP, and EP Pharmacopeia requirements.
The specifications are international common standards, which are fully compatible with the autosamplers of Aijiren, Worcester, Shimadzu and Thermo Fisher. The product is clean, dust-free packaging, no additional cleaning is required, and it can be used directly on the machine

The 4ml 13-425 Screw Thread Autosampler Vial prioritizes safety and security in sample handling. The borosilicate glass material is non-reactive, ensuring the integrity of the sample and preventing any unwanted interactions.

Red PTFE / white silicon separator + black cap without holes, 15x45mm vial for 4ml screw top vial has 13-425 GPI thread, can hold up to 4ml samples. Use a 13 x 425 cap with a septum when using it as a sample vial, or a diffusion cap for a cleaning vial. Sealed screw seals allow these vials to also be used as storage vials.

The 13-425 HPLC Vial produced by Aijiren can be applied to the Autosampler with a 13mm diameter automatic grabbing arm. The 13-425 Screw thread is also easier to grab and not fall off. It is a high-quality choice for HPLC experimental analysis.
