Aijiren Factory 18mm headspace vial metal screw cap for sale

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 20mm head decrimpers fit standard laboratory vials and are designed to seal vials with aluminum caps. The ergonomic curved handle provides more hand comfort during use compared to metal handle designs. The vial pull handle provides a firm grip. An easily visible adjustment knob is located on the head of the decrimper, making it easy to determine when the desired setting has been reached.

The Lab Use 9mm 2ml HPLC Autosampler Vial for Supply is a specialized vial designed for high-performance liquid chromatography (HPLC) applications. With a 9mm thread size, these vials ensure a secure and leak-proof seal, preventing sample contamination and maintaining sample integrity during analysis.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Suitable for: 18mm screw top headspace vials
Cap material: magnetic metal
Cap features: 8mm center hole
Color: Metallic Silver
Septa material: PTFE / silicone

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.

Aijiren™ reusable reagent bottles are made of high-quality borosilicate 3.3 glass. These bottles have excellent chemical resistance and are ideal for storing reagents, culture media, biological fluids, and various other aqueous and non-aqueous solutions.

The 20mm Caps with Septa are specifically designed for secure sealing and precise analysis of headspace samples in laboratory settings. These caps have a 20mm diameter, ensuring a tight and reliable fit on crimp headspace vials. The septa, made of high-quality materials, provide excellent sample integrity by preventing contamination and evaporation during storage and analysis.

Suitable for 11mm 2ml Crimp Neck Vials & 20mm Headspace GC Vials
Caps Material: Aluminum
Use Together with PTFE/Silicone Septa or Rubber Stopper
Color: Metal Silver
Vial Septa & Rubber Stopper and Crimpers are also Provided

Storage glass vials made of type 1, type A, 33 expanded borosilicate glass or 51A amber glass, with a capacity from 20mL to 60mL, provide a constant pH value to maintain the life of the sample, chemically inert caps are suitable for large For most chromatography and storage applications, top PTFE/silicone septa are used for cleaning.

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.

1.5ml 9mm Screw Neck Vial for automatic samplers is made of low metal type 33 and 51 COE borate glass to prevent sample instability or leaching. By selecting the cap and pad, we provide the best sealing solution for the sample.

Polypropylene screw cap with septum-The polypropylene screw cap with septum provides an anti-evaporation seal. The double layer includes silicone and PTFE. The silicone septum can be injected multiple times. Screw caps lined with PTFE are used for organic samples. The screw cap provides an inert, air-tight seal and can be directly pierced through the sample with a syringe needle.

Screw cap vials are universal. When the cap is screwed on, a mechanical force is applied that compresses the septum between the rim of the vial and the cap. Screw caps provide an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

Aijiren’s syringe filters and vials reduce HPLC sample preparation time and the use of consumables, and the track-etched membrane is also essential for extruding liposomes for encapsulation and targeted drugs.

2 ml transparent borosilicate glass refers to a type of glass that is transparent and composed primarily of borosilicate composition. Borosilicate glass is a specific type of glass non for its excellent thermal and chemical resistance properties.transparent borosilicate glass is valued for its combination of transparency, thermal resistance, chemical resistance, and durability, making it a versatile material for various practical and scientific applications.

Aijiren’s syringe filter with nylon membrane is compatible with a variety of solvents and is very suitable for rapid filtration of most aqueous and organic solutions. Therefore, when the mixture of the sample aqueous solution and the organic solvent passes through the membrane, the fine droplets of the extraction solvent gather and separate from the sample aqueous solution. The nilong syringe filter produced by Aijiren is environmentally friendly and has no centrifugal effect. By filtering the receptor phase, it can provide a higher sample purification rate.

The shell of PTFE Syringe Filter is made of polypropylene (PP) with excellent chemical stability. It is made of different colors, which is convenient for users to distinguish products of different materials and avoid confusion. The filter membrane adopts imported high-performance filter membrane with stable product quality and good reproducibility. It is an ideal choice for laboratory filtration of samples. The standard interface is convenient to connect to various syringes, and it can also be directly connected to the needle of the 7725 valve, and the sample can be injected directly after filtration.

The 18mm Screw Headspace Vial and Cap with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace Vial and Cap with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm Headspace Vial and Cap is preferred for the following instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu, Aijiren.

The hand crimpers are suitable for sealing aluminum caps of different sizes and are available as adjustable precision crimpers. The adjustable manual crimper provides an adjustable stop on the handle to ensure consistent tightening and loosening of the cap each time, and the depth of the crimp can be changed by adjusting the screws in the metal crimp.
