Chromatographic autosampler vials are glass vials used for chromatographic autosampling in liquid chromatographs, gas chromatographs, mass spectrometers and other autosamplers and headspace samplers. Generally consists of a complete set of vial, cap and gasket. Its basic requirements are accurate volume, can withstand a certain pressure, good sealing performance, no adsorption effect on the sample.

screw vials are also available in different sizes, and the cap is made of PP for sealing. The glass vial has a maximum capacity of 2ml and has a screw cap. The insert can be used with any autosampler and fits standard or wide-mouth vials.

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.

Aijiren is a company that has been engaged in the production of HPLC vial with Cap for more than ten years, and we are also a supplier, selling our HPLC Vial with Cap at the factory price.
HPLC 2ml Vial is mainly made of two glasses, Clear glass and amber glass present similar inertness. Amber glass is used for avoiding exposure of sensitive samples from UV light. The markings on the vials are useful for sample identification information. The HPLC vials can be suitable employed to inject samples from an autosampler. They come in variety of sized, 2mL vials being ubiquitously used.

Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All?Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer¡¯s specifications.Aijiren Tech vials are available in 6ml, 10ml, 20ml versions with Screw and Crimp type.

PTFE: is perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances. Hydrophobic so provides chemical resistance to aggressive media and excellent temperature stability allowing an extended sampling range. If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol). Can also be used to prevent moisture passing through air vents. pH range ~1-14.

The Aijiren 20mm manual crimpers fit standard laboratory vials and seals with aluminum caps. The ergonomic curved handle provides more hand comfort during use compared to metal grip designs. The bottom pull handle allows for a steady hold and there is no more “extra” squeeze required. An easily viewed adjustment knob is located at the head of the crimper so that it is easy to determine when the desired crimp setting has been reached.

Headspace vials are a type of sample container used in analytical chemistry, specifically for headspace analysis. Headspace analysis involves the analysis of volatile compounds present in the gas phase above a sample. These volatile compounds are typically of interest in applications such as gas chromatography (GC) or gas chromatography-mass spectrometry (GC-MS).
Headspace vials are designed to hold the sample and create a sealed environment for the vapor phase above the sample. The vials are typically made of glass, although plastic vials are also available. The vials have a specific volume capacity, which can range from a few milliliters to several tens of milliliters, depending on the application.

The Screw Cap and Septa for 1.5ml HPLC Autosampler Vial are essential components for secure sealing and sample integrity in HPLC analysis. The screw cap ensures a tight and leak-proof closure, preventing any contamination or loss of samples. The septa, made of high-quality materials, provides excellent chemical resistance and ensures a reliable seal.

Aijiren reusable media 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.

Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer’s specifications.Aijiren Tech vials are available in 10ml, 20ml versions with Screw Top.

0.45 syringe filters are commonly used in research and laboratory settings for a variety of filtration applications. They are known for their ability to remove particles and microorganisms from solutions, making them a valuable tool in many scientific fields. However, with so many options and considerations to take into account when selecting a syringe filter, it is common to have questions and concerns.
In this article, we will address 20 frequently asked questions about 0.45 syringe filters and provide comprehensive answers to help you make informed decisions about your filtration needs.Filter your sample before chromatography instrument, it can help your chromatography instrument. Aijiren lab membrane syringe filter is the best choice.

Aijiren is a professional supplier of chromatography consumables. Aijiren not only provides 20mm Crimp Top Closures, but also provides matching Headspace Vial, Hand Crimper and Decrimper. The 20mm Crimp Top Closures has a strong sealing performance, and the combination of rubber and PTFE makes Closures have better sealing performance and is very convenient for automatic injection needle puncture. Aijiren has 20 years of experience in producing gas chromatography consumables. The high-quality products and strict review system have made Aijiren successful until now.

PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.

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.

Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. 2ml Autosampler Vials 8-425 Neck surface finish is representative of hplc vials &GC vials

The vial caps of the storage series are made of the main quality polypropylene, which combines innovation with time-saving convenience. The chemically inert vial cap produced by this method truly combines the septum and the plastic cap at the molecular level, which can avoid excessive evaporation and keep the sample vial properly sealed.

10ml 20ml Headspace GC vials are a type of sample vial used in gas chromatography (GC) analysis.
They are specifically designed for the analysis of volatile and semi-volatile compounds present in a sample.
Headspace analysis involves the extraction of volatile compounds from a solid or liquid sample into the gas phase for injection into a GC instrument.
20mm aluminum caps and septa are commonly used in chromatography applications, including gas chromatography (GC) and high-performance liquid chromatography (HPLC). They are used to seal sample vials and ensure a gas-tight or liquid-tight seal.
