Screw Caps with Septa for 8-425 HPLC Vial

Autosampler vials are available in a variety of sizes, with 2 mL vials being the most common size. During the injection process, the autosampler needle pierces the cap and extracts the desired amount of analyte from the vial. There are different types of vials for chromatography applications.

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.

10mm sample bottles are widely used in the pretreatment of samples analyzed by gas chromatography and liquid chromatography. With the development of testing technology and the improvement of testing standards, the quality requirements for sample bottles have also increased. The 10mm large opening of Aiji can effectively prevent the risk of injection needle deviation.

Chromatography sample vial is a glass vial used by automatic samplers and headspace samplers such as liquid chromatography, gas chromatography, mass spectrometry, etc. for chromatographic automatic sampling.  10-425 Screw Glass vial For autosampler instrument is made of borosilicate glass.

Glass Vial Inserts for 2ml HPLC Vials
Volume: 150ul, 250ul, 300ul
Bottom Type: Mandrel Interior & Polymer Feet; Conical Bottom, Flat Bottom
Suitable for : 8-425, 9mm, 10-425, 11mm Vials

These screw neck vials feature a 4ml capacity, providing ample space for storing liquid or solid samples. The screw neck design allows for easy and secure sealing, preventing leakage and contamination. The vials have a wide opening, facilitating convenient sample loading and retrieval.

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.

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 12*32mm. 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. 

Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.

2mL Clear Amber Glass Screw Top Autosampler Vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Amber Glass Screw Top Autosampler Vial, the product material is of paramount importance.

The workers of Aijiren in the picture are packaging the Micro-Insert. This kind of Micro-Insert is usually suitable for Autosampler Vial. For the Autosampler Vial of 9mm, 10mm, 11mm caliber, the capacity is 300ul, and the outer diameter is 5 or 6mm micro-insert. Both can be adapted, but for Autosampler vials with a diameter of 8mm, only micro-inserts with an outer diameter of 5mm can be used.

2mL Amber Glass Screw Top Autosampler Vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Amber Glass Screw Top Autosampler Vials, the product material is of paramount importance.

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 opening of the vial produced by Aijiren is 40% larger than the standard opening aluminum sealed bottle
It is made of transparent Class 1 Class A or Amber, Class 1 Class B borosilicate glass
Sample vials provide standard progressive pasteable patches for easy filling and identification

The aijiren chromatography sample vial is made of borosilicate glass and meets ASTM TYPE I ClassA and USP TYPE I standards.
There are four types: colorless and amber vial, handwriting area and no handwriting area.

11mm chromatography autosampler vials are widely used in chromatography, chemistry, medical and other fields. 11mm autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. Different vial mouth designs meet different actual needs.

Polypropylene caps are known for good impact strength, cost effectiveness, and pliability. They can be remelted after they are formed. Aijiren Polypropylene cap is widely used in chromatography analysis.

PTFE is the most inert, but it has poor resealability, so it is not suitable for multiple injections or storage. For layered septa (such as PTFE/silicone), the chemical resistance of the septum is PTFE until the septum is punctured.

screw vials are also available in different sizes, and the cap is made of PP for sealing. The glass vial has a maximum capacity of 2ml and has a screw cap. The insert can be used with any autosampler and fits standard or wide-mouth vials.
