13mm Polypropylene Screw Caps | Septa-Free Closure

2 ml borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis.Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.When working with water samples in HPLC, borosilicate glass vials are a suitable choice due to their resistance to water and other polar solvents.

4ml Autosampler Vial is produced by our Aijiren Instrument Co., Ltd. using high-quality imported raw materials from abroad, with high temperature resistance and corrosion resistance; the lid is made of high-quality polypropylene, with precise manufacturing tolerances, and controllable manufacturing Environment, to win the trust of customers with high-quality quality and service; the septum of the?autosampler vial?adopts the highest quality materials to ensure proper function, and is widely used in multiple injections and/or longer sampling cycle design and meteorological chromatography Instrument and liquid chromatograph.

The 13mm septum uses only high-quality materials to ensure proper function. It can be slit in advance to facilitate needle penetration. It is especially suitable for liquid chromatograph applications. It is guaranteed that the septum will not fall into the sample during the sampling process. In the bottle. This septum is made of PTFE/silicone fusion, they have excellent inertness and can be used for multiple injections.

Aijiren is a supplier of 13-425 Screw Neck Vial. Our factory specializes in the production of 13-425 Screw Neck Vial for chromatography.

4 ml HPLC borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis. Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.

Among the HPLC Vials provided by Aijiren, there is an HPLC Vial with a capacity of 4ml, which is twice as large as the popular 2ml hplc vial, and its caliber is also larger than the ordinary hplc vial, which is 13mm wide. The large-capacity Vial can accommodate more samples, and the wide caliber can also accommodate the in and out of the thick-mouthed automatic injection needle. 4ml HPLC Vials is very suitable for the analysis of equipment with a large number of samples.

The 13-425 automatic sampling vial is produced by our company using high-quality imported raw materials from abroad. It is resistant to high temperature and corrosion; the cap is made of high-quality polypropylene, and the septum is made of the highest-quality material. Manufacturing tolerances and a controllable manufacturing environment ensure the high efficiency of product functions.

The vial cap corresponding to the 4ml screw vial combines innovation with time-saving convenience. The chemically inert bottle cap produced by this patented method truly combines the septum and the cap at the molecular level, which can avoid excessive evaporation and keep the sample bottle properly sealed. The thickness of the 13mm septum is 1.5mm, and the PTFE is about 0.1mm.

The 13-425 provided by Aijiren is made of high-quality borosilicate glass. The transparent glass can clearly see the sample and the state of the sample in Vias, and can more intuitively understand the color contrast and sample change. The lid of 13-425 is Screw Thread. This kind of lid facilitates the sealing operation of HPLC Vial.

Black PP material with leak-proof closed-top design. Septa-free structure prevents sample contamination. Fits standard 4ml vials.

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
