Black PP Caps with Center Hole

12ML amber sample vial with black solid cap natural PTFE/natural silicone septa

PTFE is the most inert but its poor resealability making it unsuitable for multiple injections or storage. For layered septa such as PTFE/silicone the chemical resistance of the septa is that of PTFE until the septum is punctured. Once punctured, the silicone layer is exposed and able to react with sample/solvent so the chemical resistance of silicone should be considered when using these septa.

0.22 um 25 mm nylon filter syringe, also known as a nylon syringe filter, is a type of syringe filter that utilizes a membrane made from nylon material. Nylon is a synthetic polymer known for its excellent chemical compatibility, high flow rates, and broad applicability in filtration processes. dis hydrophilic property allows teh membrane to wet rapidly when in contact wif water, enabling efficient filtration of aqueous samples.

Empty glass HPLC vial refers to a type of vial specifically designed for use in High-Performance Liquid Chromatography (HPLC) applications. HPLC is a technique used in analytical chemistry to separate, identify, and quantify components of a sample mixture.
HPLC vials are made of glass to ensure chemical compatibility and to minimize sample contamination. These vials typically have a capacity ranging from 1.5 mL to 2 mL, although other sizes may be available. The vials have a narrow neck and a screw cap or crimp cap closure system to secure the contents and maintain the integrity of the sample during analysis.

The Screw Caps that are inlcuded with this kit are knurled on the sides for excellent gripping and comfort when applyting to the vial.

Due to their artificially reduced cap height screw caps don’t have a standardized thread design. Therefore, it is recommendable only to use vials and closures from one source of supply, in order to ensure a harmonious and tight matching of both components

Headspace vials are a type of laboratory vials used for gas chromatography. They are designed to contain samples that will be analyzed using headspace gas chromatography, a technique used to analyze volatile compounds in solid or liquid samples. The vials are sealed with a septum cap, allowing the headspace above the sample to be analyzed without exposing the sample to the atmosphere. This technique is commonly used in pharmaceutical, environmental, and food analysis, among other fields.
Headspace vials, also known as gas chromatography (GC) vials or sample vials, are specialized containers used for the analysis of volatile compounds in gas chromatography. They are designed to store samples and create a headspace above the sample, which contains the volatile components to be analyzed.

18mm Magnetic Metal Cap with Center Hole for more convenient for the automatic injection needle to perform sample injection.Generally speaking, the Septa in the 18mm Closures uses a double-sided compound of Silicone and PTFE Septa, which makes it difficult for Septa to react with reagents, and it can also protect impurities in the air from falling into the vial.

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.

Aijiren™ Reagent Bottles, also known as Media Bottles, are manufactured from high quality borosilicate 3.3 glass. With their superior chemical resistance, these bottles are ideal for storing reagents, culture media, biological fluids, and a variety of other aqueous and non-aqueous solutio

Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.

PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Test Tube is a term that can refer to different things depending on the context. In a scientific context, a test tube is a cylindrical glass or plastic tube used to hold and mix small amounts of liquid during experiments in laboratories. It is commonly used in chemistry, biology, and other scientific disciplines.
In a broader sense, “Test Tube” can also refer to a YouTube channel called “TestTube,” which is a popular science and educational channel owned by Discovery Digital Networks. The channel covers a wide range of topics, including science, technology, history, and culture, and provides informative and entertaining videos for viewers.

The COD Test Tubes produced by Aijiren are often used for chemical oxygen demand detection. The glass used in the COD Test Tubes produced by Aijiren has high temperature resistance, corrosion resistance, and can well protect the samples without affecting the experimental results. Aijiren’s raw materials are of high quality and production experience Abundant, with favorable product prices, it is a high-quality supplier of chromatographic consumables.

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.

Our 9 mm wide mouth vials and caps are our recommended screw bottles. These vials are compatible with autosamplers and have an opening 40% larger than 8-425 threaded vials, simplifying pipetting and other routine functions. Aijiren Tech provides 9mm clear glass bottles and amber glass bottles, as well as polymer options and qualified glass bottles.
