PTFE Silicone Septa for 2ml vial cap

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.

Chromatography autosampler 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. Its basic requirements are accurate volume, ability to withstand a certain pressure, good sealing performance, and no adsorption to samples.

The crimp top provide the tightest seal, reducing the possibility of sample volatilization. The 12X32mm crimp vial and aluminum cap are the most economical choice, and it is also very convenient to use with the crimp tool.

2ml Snap Top HPLC Vial is made of Type 1 borosilicate glass. Comparing with 9mm screw vial, this 2ml Snap Top HPLC Vial mouth is wider opening. So 2ml Snap Top HPLC Vial is easier to fill and provides a larger target area for the autosampler needle. That means, the 2ml Snap Top HPLC Vial can protect the needle.

Glass inserts with polymer feet. Conical with precision-formed mandrel interior, 250ul. These types of small-volume inserts are available for use with 2ml Autosampler screw-top vials. Made with high precision, these inserts offer reliability and will not contaminate your samples. Simply drop them into your autosampler vials for use.

Snap Vials are manufactured from Type 1 borosilicate glass(Class A, 33 expansion borosilicate glass), available in clear or amber, or from Polypropylene. Snap Vials accept both an Aluminum Snap Seal as well as a Polyethylene Snap Cap. Excellent for short-term storage. Deactivation, MS Certification is also available.

If the weight, damage, surface inertness, and/or disposal costs of the glass vial are concerned, the vial manufactured from polypropylene is an alternative to consideration. The benefits of polypropylene materials include low extraction rates, compatibility with many solvents, ideal for working with proteins, ideal for ion chromatography applications, ideal for pH-sensitive sample storage, and eliminate the need for inserts during microsampling.

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.

HPLC autosampler vials  are generally categorized by 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. 

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.

We provide the protection of PTFE and the resealing ability of silicone with our septa and seals to fit our autosampler crimp top vials. This seal includes a two sided PTFE septa with silicone in the center.

Micro-vials are small containers or vials designed to hold very small volumes of liquid or samples. They are typically used in scientific research, medical diagnostics, and pharmaceutical industries, where precise and accurate measurements of small quantities of substances are required.
Micro-vials are commonly made from materials such as glass or plastic, depending on the specific application. They are designed to be airtight and leak-proof to prevent contamination or loss of the sample. The vials often have a small opening or cap that allows for controlled dispensing or extraction of the liquid or sample.

11mm Snap caps provide a secure seal, minimizing evaporation even with volatile samples, the audible click ensures that a secure seal has been formed and the cap is properly applied. Snap caps have septa pre-assembled, Snap caps are compatible with Aijiren Vials and other snap-ring style vials.

1 mm shell vials typically refer to small, cylindrical vials with a thin outer shell. They are commonly used for chromatography applications, such as gas or liquid chromatography. Micro-vials generally refer to very small vials with a reduced volume capacity. They are often used for storing small quantities of samples or for high-throughput analysis in laboratories.Integrated screw snap crimp vials combine the features of screw vials and crimp vials. They typically have a threaded neck that allows for easy screwing of a closure, such as a screw cap, and also feature a snap-top design that allows for secure crimping.

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

The Aijiren sample vial is sealed and effectively avoids sample evaporation. The 11 mm aluminum cap corresponding to the vial can be easily and quickly combined with the jaw capping tool. Vials can withstand heat and pressure and can also be used for chemical reactions. It can be used as an anesthermal and oxygen-free reaction viale, especially for white open caps and thick PTFE/silicon septum viars.

The Lab Use 1mL Shell Vial is a compact and convenient tool designed for laboratory sample handling. With a 1mL capacity, these shell vials are ideal for storing and transporting small liquid samples. They are made of high-quality glass, ensuring excellent chemical resistance and visibility for easy sample inspection.
