13mm Screw Neck PP Caps suit for 4ml Glass Vial

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 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 function and is widely used in multiple injection or longer injection cycle designs as well as gas and liquid chromatographs.  

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.

The 13-425 vial provided by Aijiren are all made of borosilicate hydrochloric acid glass, which is extremely inert and difficult to react with chemical reagents, which can effectively ensure the accuracy of the experimental results.

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.

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.

4ml 13-425 HPLC vial with cap is used for chromatography system. In the experimental system, the automatic sample system has the high-tech innovation ability, can improve the productivity of the chemical laboratory, and achieve excellent results in efficiency, safety and replicability. Therefore, 4ml 13-425 HPLC vial is also of great concern.

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.

Aijiren 13-425 glass vials with screw cap are customized products based on your experimental requirements for vial types, writing areas, logos and other individual parameters. Aijiren 13-425 glass vials with screw cap is fully compatible with SHIMADZU autosamplers. Compared to crimp top vials, 13-425 glass vial with screw cap can easily tighten the lid without the help of a tool. Polypropylene threaded cap with PTFE septa, can form a good seal on the vial, improve work efficiency.

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.

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.

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.

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.

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.

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.
