The 13-425 vial is widely used in the design of multiple injections or longer sampling periods, as well as weather chromatographs and liquid chromatographs. The thread is precisely machined to ensure sealing at all times. It fits perfectly with the matching 13mm black and white opening, solid cover and various septa.

4ml 13-425 hplc vial with screw cap is belong to HPLC autosampler vials. The classification of HPLC autosampler vials is generally done based on the diameter of the vial body, vial height, and thread finish. Clear glass and amber glass present similar inertness. 4ml 13-425 hplc vial with screw cap is compatible to SHIMADZU instrument. Autosampler needle pierces through the cap during injection and withdraws the required amounts of analyte from the sample vial.

4ml 13-425 screw thread Vial Made of Clear, Type 1 Class A or Amber, Type 1 Class B borosilicate glass,Requires the use of 13-425 closures and 13mm septa. For storage purposes also available with closed top screw seals, Available as closed or open top screw seals with13-425 thread.

Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

4mL vials are widely used in compound storage as well as for chromatography sample vials. Vials are manufactured of Clear, or Amber borosilicate glass and include a write-in patch for sample identification.

Aijiren is a supplier of 13-425 Screw Neck Vial. Our factory specializes in the production of 13-425 Screw Neck Vial for chromatography. We use good raw materials to make 13-425 Screw Neck Vial and sell them at a cheap price while ensuring quality. Aijiren’s high quality and low price have satisfied many customers.

Aijiren’s 4ml 13-425 Vial for HPLC is a popular product. Aijiren uses high-quality borosilicate glass to make Via, good PP plastic to make the lid, Silicone’s Septa, these excellent accessories combine to become Aijiren 4ml 13-425 screw vial.

Glass autosampler vial, 4ml, 15mm x 45mm, used with 13-425 screw caps.
Ideal for general laboratory use and sample storage.
Chemically inert caps suitable for most chromatography and storage applications.
Top grade PTFE/silicone septa used for cleanliness.

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.

1. The glass adopts high-quality borosilicate glass tube, with low free ion content, low expansion coefficient and very high chemical resistance.
2. The unique thread design can ensure the consistency of the seal.
3. Strict quality assurance provides dimensional consistency between batches.
4. It is suitable for autosampler of Aijiren, Shimadzu, Waters, CTC/Leap and other companies.

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.

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.

13-425 Screw Thread Vials are manufactured from Type 1 borosilicate glass, available in clear or amber, or from Polypropylene. Excellent for long-term storage.
15x45mm 4mL vials are widely used in compound storage as well as for chromatography sample vials.

The 4ml screw neck glass vial produced by Aijiren is often used in Autosampler. The 4ml 13mm opening is convenient for automatic injection needle injection. The Cap has a center hole. PTFE and Silicone are compounded on both sides to ensure that one side of PTFE faces the reagent inside Vias, ensuring that the stability of the reagent is not destroyed.

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.

The Aijiren 15x45mm vial has a 13-425 GPI thread that can hold up to 4ml of 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.

Aijiren Sample Storage Vial is usually used for environmental analysis. Clear Glass Vial can better see the state of the sample. Amber Glass Vial can withstand ultraviolet light and protect the chemical components in the sample that are sensitive to ultraviolet light.
