8mm Screw Ring PP Caps

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.

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.

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.

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.

The Screw Cap and Septa for 1.5ml HPLC Autosampler Vial are essential components for secure sealing and sample integrity in HPLC analysis. The screw cap ensures a tight and leak-proof closure, preventing any contamination or loss of samples. The septa, made of high-quality materials, provides excellent chemical resistance and ensures a reliable seal.

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.

Aijiren’s HPLC Vial is divided into two types: clear glass and amber glass. The clarity of clear glass is more obvious. The reagent changes in the vial can be clearly seen. The amber glass can protect the sample in the vial from deterioration due to ultraviolet radiation.

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.

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.

If the reagent to be tested by the customer is very precious and the capacity of 2ml vial is too large, Aijiren 8-425 2ml Autosampler Vials can be used with different types of micro-insert. There are 3 types of micro-insert, 29*5mm 150uL micro-insert with mandrel interior&polymer feet, 150uL conical bottom micro-insert and 250uL flat bottom micro-insert. All three types of micro-insert can be adapted to 8-425 2ml Autosampler 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.

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 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.

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

Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The

The specifications of the vials are 12 x 32 mm.
Accurate handling of bottlenecks to enable the mechanical arm to operate efficiently.
Suitable for Aijiren, AB Sciex, Brukers, Techcomp, PerkinElmer, ThermoScientifics, Shimadzu, Waters, CTC autosamplers, and other rotating or robotic arm samplers.
40% larger opening than the standard narrow opening vial prevents syringe problems
The special screw design ensures a consistent seal.

8-425 thread caps and viars are often used in combination with Shimadzu, Specra-Physics, Varian, and other autosamplers
The vial is made of transparent type 1 class A or amber, type 1 class B borosicate glass and contains writing patches for sample identification.

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.

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. 

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.

Constructed from high-quality borosilicate glass, these autosampler vials offer exceptional chemical resistance and thermal stability. The 8-425 thread finish allows for easy and efficient sealing, ensuring hassle-free sample preparation.
