Standard GC, HPLC sample vial, small caliber, 8-425 standard threaded mouth, can be used for autosampler and sample storage. It can be used with 8-425 screw cap septum.
8-425 Autosampler Vial, often used in conjunction with Shimadzu, Spectrophysics, Varian, and other autosamplers. The vial is made of colorless Class 1 Type A or Amber Class 1 Type B borosilicate glass , And attached with a writable label for sample identification.

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.

These HPLC vials feature an 8-425 thread size, making them compatible with a wide range of HPLC instruments. The precise thread design allows for a tight and reliable seal, preventing any potential leakage or contamination. The vials have a clear glass construction, enabling easy visibility and inspection of the sample.

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. 

Chromatographic autosampler vials are glass vials used for chromatographic autosampling in liquid chromatographs, gas chromatographs, mass spectrometers and other autosamplers and headspace samplers. Generally consists of a complete set of vial, cap and gasket. Its basic requirements are accurate volume, can withstand a certain pressure, good sealing performance, no adsorption effect on the sample.

The 8-425 Screw Cap with Septa for 8mm Vial offers compatibility with a wide range of laboratory applications. They are commonly used in chromatography techniques, such as High-Performance Liquid Chromatography (HPLC). These screw caps are suitable for both routine analysis and research applications, ensuring reliable and reproducible results.

Aijiren has been producing 8-425 2ml hplc glass vial for more than ten years. During this decade, Aijiren added new factories and production lines to strictly regulate production standards and processes. Continuous improvement has made Aijiren one of the largest laboratory consumable suppliers in southern China.

The screw top vial design is characterized by general ease of use, especially with autosampling systems, hence the name autosampler vial. The 1.5 ml vials are commonly referred to as 2 ml capacity vials.

The 1.5ml and 4ml HPLC Autosampler Vials are essential tools for sample storage and injection in High-Performance Liquid Chromatography (HPLC) systems. These vials are made of high-quality materials, such as borosilicate glass, ensuring excellent chemical resistance and sample integrity.

1.5ml/2ml 8-425 autosampler vial (Shimadzu chromatography sample vial) is provided by Zhejiang Aijiren Rechnology Co., Ltd., instead of imported Shimadzu sample bottle, standard GC, HPLC sample bottle, 5MM caliber, 8-425 standard Threaded port can be used for autosampler and sample storage. It can be used with 8-425 screw cap septum. The bottle cap is made of high-quality polypropylene, and the septum is manufactured with high-quality materials to ensure the efficiency of the function.
Applicable to: Beckman, Diane, Finnigen, Gilson, LKB, Thermoelectric Thermo, Varian Varian, Shimadzu and other autosamplers.

The automatic vial is made of high quality raw materials. 2ml Autosampler Vials 8-425 neck finish represents a hplc vials &gc vials, the vials a diameter of 8 mm across the outside of the threads and a thread style of 425, Vials has clear and amber, Screw Cap in Lab most of the 2ml vials are 12x32mm.

Compared with crimping seals, threaded vials and caps have lower evaporation, reusability, less damage to hands during operation, and no special tools are required. The 8-425 neck mouth represents a vial with a diameter of 8mm. The outer diameter of the thread of the vial is 8mm, and the thread pattern is 425.

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.

The design of Aijiren screw thread top vials is developed from Europe and the United States, and the design feature is easy to use, especially the use of an automated sample introduction system. 

Screw cap vials are available with either an open hole for autosampler use and standard addition or a solid top for sample storage. One-piece polypropylene caps and membranes are also available. These pierceable screw caps are designed for single use and reduce sample preparation time by eliminating the need to assemble the cap and liner.

Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. 2ml Autosampler Vials 8-425 Neck surface finish is representative of hplc vials &GC vials

We provide septa and caps to fit our autosampler crimping the top vial to provide PTFE protection and silicone resealability. The cap includes a double-sided PTFE septum with silicone in the middle.

Let me introduce the material of 8-425 2ml autosampler vials, 33 Expansion borosilicate glass USP Type I Class A made of clear vial, or 51 Expansion borosilicate glass USP Type I, Class B made of Amber vial.Our glass uses neutral borosilicate and low borosilicate, but our neutral borosilicate can reach the standard of high borosilicate, and our low borosilicate can reach the standard of neutral borosilicate. We use excellent raw materials to make 8-425 2ml autosampler vials.

PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

The thread design of the 8-425 threaded sample vialcan make the septum achieve extremely strong re-tightness, so this sample vial can also be used as a storage vial, and it can also be used for autosampler. This design sample vial is mostly suitable for Shimadzu Hitachi and other Japanese enterprise instruments.
