Aijiren flat bottomed EPA vials are available in 40 sizes, suitable for water or soil samples. They are made of(offered in) chemically inert Type I borosilicate glass, in either clear or amber for light sensitive samples. The 40 mL vials are offered in clear (Type 1, 33 expansion) and amber Type 1, 51 expansion) borosilicate glass. They are avialable in two sizes, 27.5 x 95mm or 29 x 82mm and are packaged 100 vials per box.

The Sample Storage Vial produced by Aijiren is suitable for environmental analysis and storage of samples. 15-425 has two different capacities, 8ml and 12ml, suitable for different types of samples.

The 20-60mL EPA VOA Storage Vial is a specialized container designed for the storage and preservation of Volatile Organic Analysis (VOA) samples in the laboratory. It has a capacity range of 20-60mL, providing ample space for sample collection and storage. The vial is made of high quality, chemically resistant material to ensure sample integrity during long-term storage.

Aijiren Storage vial is an ideal device for general laboratory use and storage of diverse samples due to excellent sealability and chemical tolerance. Besides, chemically inert caps are a good choice for most chromatography and storage applications. Top grade PTFE or Silicone septa are adopted to ensure cleaning production and consistent quality of sample vials.

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.

Trust our certified vials for Total Organic Carbon testing and sampling. TOC-certified products are manufactured, packaged and tested to exacting standards.

Manufactured in state of the art moulding facility using high purity virgin polypropylene.
PP Material confirming to US FDA 21 CFR.
Used for storage of PCR reagents, enzymes and other diagnostics and biochemical reagents or sample.

Storage Vial is supplied by Aijiren. These vials are pre-sterilized and have a capacity of 5ml. These vials can be used for storing biological material, human and animal cells. The cap is provided with a built-in seal ring which makes the vial leakproof. The base of the vial has longitudinal grooves which gives it a non-twisting character when placed in a vial rack.

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. Caps are made of high quality polypropylene, Caps have the profile of a crimp or snap closure for compatibility with robotic autosamplers, Pre-assembled septa reduces the chance of contamination during sample preparation, while saving sample preparation time in the lab.

EPA vials are those that meet the requirements of the US Environmental Protection Agency (EPA) for the testing of potentially harmful environmental contaminants in water or soil samples. To be used for environmental analysis, EPA vials must be clean and free of substances that might influence the analysis.

The storage vials are compatible with various laboratory storage methods, including refrigeration and freeze-drying. They can withstand a wide range of temperatures, allowing for long-term storage of samples under different conditions. The PTFE cap provides chemical resistance and ensures a tight seal, even during extreme temperature fluctuatio

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.

Our storage vials, also known as step vials or dram vials offer a great solution for storing solvents for extended periods of time. Our screw thread vials offer enough threads per inch to eliminate evaporaton with a solid top or lined cap.

Aijiren not only produces Vial for HPLC and GC, but also Sample Storage Vials for storing samples. Aijiren’s Sample Storage Vials are divided into amber and clear vials. Amber vial can protect the sample from ultraviolet rays.

Aijiren uses type 1, type A, 33 expanded borosilicate glass or 51A amber glass for storage glassware, with a capacity from 20mL to 60mL, providing a constant pH value to maintain the life of the sample.

Red PTFE/White silicone septa + Black cap without hole, for 4ml screw top vial SV104CS 15x45mm vials have a 13-425 GPI thread and can hold up to 4ml of sample. Use the 13 x 425 caps with septa for use as sample vials and with diffusion caps for wash vials. With closed top screw seals, these vials can also be used as storage vials.

Aijiren is manufactured in the most advanced molding equipment using high-purity pure polypropylene.
PP is a material that complies with US FDA 21 CFR. Used to store PCR reagents, enzymes and other diagnostic reagents, as well as biochemical reagents or samples. The screw cap has leak-proof function and can be used at low temperatures.

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 Vial, the product material is of paramount importance.
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volumes with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.
