In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. Therefore, samples and solvents must be pre-filtered to remove particulate contaminants and protect the instrument.

Aijiren sample vials have excellent sealing performance, which can effectively avoid sample evaporation. The sample bottle and corresponding 11 mm aluminum cap can be easily combined with the crimp cap tool. The vial can withstand heat and pressure, and can also be used for chemical reactions. Especially for sample bottles with white open caps and thick PTFE/silicone septa, they can be used as anhydrous and oxygen-free reaction bottles.

Aijiren is made of high-quality USP 1 expanded 33 borosilicate clear glass (USP Type 1, Type A) or 51 amber glass. The bottom of the vial is even and flat to ensure the safety of the blade. The sample vial has a writable spot and can provide 0.5, 1.0 and 1.5ml graduations.

PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes.

These vials are the preferred choice for modern autosamplers. With a focus on improved sample security and integrity, we now offer innovative 9mm closures and 9mm screw top vials for consistent productivity on every separation. Standard opening screw-thread vials are manufactured from borosilicate glass and have a maximum fill volume of 2 ml.

All of Aijiren 2ml vials are excellently fitted for autosamplers and have good chemical compatibility and super cleanliness. The crimp top sample vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use. At the same time, some vial bottoms are designed with round bottoms, so that it has a flat bottoming function and compatibility with automatic sampling equipment.

Tube tests for photometric analysis convince by their easy handling and therefore are the first choice for routine, laboratory and process analysis. A maximum in accuracy and precision is granted for the measurement results due to exactly pre-dosed reagents in 16 mm cuvettes and additional reagents.

The membrane filter in a syringe filter is typically made of materials such as cellulose acetate, nylon, polyethersulfone (PES), polypropylene, or polytetrafluoroethylene (PTFE). These materials are chosen based on their compatibility with the substances being filtered and their ability to retain particles of a specific size.It consists of a plastic housing with a membrane filter at one end and a connector at the other end that allows it to be attached to a syringe.

Headspace GC (Gas Chromatography) vials are specialized sample vials used in headspace analysis. Headspace analysis is a technique used in analytical chemistry to analyze volatile compounds in a sample.
In headspace analysis, a sample is placed in a sealed vial, and the volatile compounds in the sample equilibrate with the headspace (the space above the sample) inside the vial. The vial is then heated to a specific temperature, causing the volatile compounds to vaporize and distribute themselves in the headspace.

Aijiren’s Caps all come with Septa, and 9mm Cap is the most popular choice, because 9mm Cap with Vial are Aijiren’s hot-selling products. The screw Neck design ensures the consistency of the seal and the pattern, and the seal is good, and it is convenient for manual operation. The operation meets the needs of laboratory personnel, and the packaging of 100pcs meets the convenience of experimental use.

Polypropylene (PP) is recommended for one time use only with low vapor transmission. Polypropylene is a rigid plastic that is translucent. At room temperature, polypropylene exhibits excellent chemical resistance to acids, alcohols, and bases. Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutyl alcohol, methanol, and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, and trichlorobenzene.

4ml borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis. Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.When working with water samples in HPLC, borosilicate glass vials are a suitable choice due to their resistance to water and other polar solvents.

15-425 Screw Sample Storage Vials made of high quality borosilicate glass for heating or autoclaving, instant syringe access to completely sealed reagents and standards. Aijiren Sample Storage Vials are available in two sizes for storage, heating and autoclaving.

The specification of 1ml Shell Vial is 40*8mm, the maximum capacity is 1ml, the neck diameter is 8mm, and the flat bottom is very convenient for the automatic sampler to draw liquid. The stability of the glass material also ensures the safety performance of the reagent.

10/20 mL screw neck headspace vial is a type of laboratory container commonly used in analytical chemistry and pharmaceutical applications.
It is specifically designed for the analysis of volatile compounds in a sample using a technique called headspace analysis.
The vial features a screw neck, which means it has a threaded opening that allows for a secure closure using a cap or septum.
The screw neck design ensures a tight seal, preventing any leakage of the sample or the escape of volatile compounds during analysis.

The Cap and Septas for 20mm Headspace Vial are essential components designed for secure sealing and reliable analysis in headspace sampling applications. The cap provides a tight closure, while the septa acts as a barrier, preventing contamination and maintaining sample integrity. This product is specifically designed to fit 20mm headspace vials, ensuring a seamless and effective sealing solution.
