Screw Caps with Septa for 8-425 HPLC Vial

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.

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.

Secure your most valuable samples with our High Quality Aluminum Crimp Caps, designed to provide reliable sealing solutions for a wide range of laboratory and industrial applications. Available in both 11mm and 20mm sizes

HPLC autosampler vials are generally categorized based on vial diameter, vial height, and thread finish. Clear glass and amber glass have similar inert properties. Amber glass is used to protect sensitive samples from UV light. Markings on the vials help provide sample identification information. Autosampler vials can be used to inject samples from an autosampler.

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 a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.

Aijiren provide 1mL 8x40mm Shell Vial Kit.Suitable for use over a wide range of temperatures, these 1ml Shell Vials are extensively tested to ensure they meet the needs of the end user. Subject to laboratory testing to ensure defined quality standards. Manufactured from the highest quality borosilicate glass.

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.

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.

Ensure the integrity of your high-performance liquid chromatography (HPLC) samples with our premium-quality polypropylene (PP) caps, designed and manufactured in China.

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 snap vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp or snap seals and no special tools are required to remove the cap. These vials are recommended for short-term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

 9mm Screw conical micro-vial for lab chromatography experiment, the micro-vial size is 11.6x32mm.  High quality glass vial for HPLC/GC analysis. 0.3 ml clear or amber  glass micro insert fixed in 2ml glass vial.

Aijiren 2ml 11mm Snap Ring HPLC Vial is made of transparent type A type 1 or amber type B type 1 type B borosilicate glass. Amber glass can effectively block ultraviolet rays and protect sensitive samples from the volatilization caused by ultraviolet rays. Aijiren 2ml 11mm Snap Ring HPLC Vial has a standard scale and writing area for easy filling and identification.

The non-pre-slit septas help to reduce carryover from vial to vial because the resealing characteristics of the septum act as a squeegee to wipe solution from the outside of the needle. Typically, a non-slit septum exhibits resealing capabilities for a limited number of needle punctures but for long-term storage in the vial, using a new non-punctured septum is best practice.

The 0.3ml PP Clear or Amber Micro Vial with a 9mm Screw Neck is a versatile and compact solution for laboratory sample storage and analysis. These micro vials are made of high-quality polypropylene (PP) material, ensuring excellent chemical resistance and sample protection. Available in clear or amber options, they offer visibility and light protection for different sample types.

Clear Glass Vial Insert is used to ensure the most accurate and reliable analysis of your lab samples. Micro inserts, when used in conjunction with autosampler vials, allow for maximum sample recovery and easier sample removal.

The 9mm hplc vial provided by Aijiren has a high recovery type, which can effectively recover samples and reduce sample residues. This high recovery 9mm hplc vial is made of extremely inert borosilicate hydrochloric acid glass, which is not easy to react with chemical reagents.

1. The glass adopts high-quality borosilicate glass tube, with low free ion content, low expansion coefficient and very high chemical resistance.
2. The unique thread design can ensure the consistency of the seal.
3. Strict quality assurance provides dimensional consistency between batches.
4. It is suitable for autosampler of Aijiren, Shimadzu, Waters, CTC/Leap and other companies.

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.
