25mm Screw Neck Vial with PP Cap

Bottles and screw caps can be autoclaved / sterilized. Made from borosilicate glass helps prevent changes in ph levels and maintain content purity. Non-slip coating allows for greater ease and stability when handling wet or dry. 45mm white polypropylene unlined screw cap comes attached to bottle to help maintain cleanliness. Pvc-based plastisol coats exterior of bottle retaining contents if bottle is accidentally broken.

Silicone septa, also known as a silicone rubber septum or stopper, is a sealing component used in laboratory settings, particularly in chromatography and sample storage applications. It is a circular disc-shaped piece made of silicone rubber that is placed within the cap of a vial or container to create a secure and leak-proof seal.
Silicone septa are commonly used in conjunction with screw caps or crimp caps to seal vials used in gas chromatography (GC) and other analytical techniques. They are typically placed between the cap and the vial opening, and when the cap is tightened or crimped, the septa forms a barrier that prevents leakage or contamination of the sample.

11mm vials for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials. Crimp vials are manufactured of Clear or Amber borosilicate glass.

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.

Aijiren finds the right size filter in order to ensure that customers can filter the particles correctly. It is recommended that you choose the diameter of the filter carefully. Aijiren produces usually sizes of 13 mm and 25 mm. Each of them has a different ability to hold particles. According to the sample size, the appropriate filter diameter can be selected. For example, a diameter of 13 mm can be used for samples of 1-10 ml. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Septa: White PTFE/Blue Transparent Silicone Septa

10ml Crimp Headspace Vial is used in gas chromatography analysis experiments. For example, it is placed on an automatic sampler, and the sample is heated to vaporize the gas, and the automatic sample needle penetrates the septa into the vial to extract the gas for detection , So the tightness requirements for Crimp Headspace Vial are higher.

Our storage bottles (also called ladder bottles or dram bottles) provide a good solution for long-term storage of solvents. Our threaded vials provide enough threads per inch to eliminate evaporation with a strong top or lined cap.

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.

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 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.

These autosampler vials possess a screw neck design that ensures a secure closure, preventing sample leakage or contamination during analysis. The screw cap can be tightly sealed onto the vial, ensuring a reliable and leak-proof seal. This secure closure mechanism guarantees the integrity of the stored samples during storage, transportation, and analysis.

Reagent bottle, also known as culture medium bottle or scale bottle, is a container made of glass, borosilicate or related substances, with a special cover on the top. They are designed to contain chemicals in the form of liquid or powder for laboratory use and are stored on cabinets or shelves. Some reagent bottles are amber (photochemical), brown or red to protect photosensitive compounds from visible, ultraviolet and infrared radiation, which may change them; Bottles are called “graded” when they are marked on the side to indicate the approximate (usually 10% error) amount of liquid at a given level in the container. Reagent bottle is a kind of laboratory glassware.

The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom.

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 2ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.

Vials are manufactured in clear type 1 class A or amber type 1 class B borosicate glass. 10-425 screw fasteners and 10mm septum must be used. See Assembly Caps and Septum Limited volume micro-insert for wide opening 10-425 vial.

Chromatography autosampler vials are widely used in chromatography, chemistry, medical and other fields. Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. Different vial mouth designs meet different actual needs.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.

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.

Chromatography vial is a glass vial used by automatic samplers and headspace samplers such as liquid chromatography, gas chromatography, mass spectrometry, etc. for chromatographic automatic sampling.  Screw Glass vial for autosampler instrument is made of borosilicate glass.

The 2ml and 4ml Borosilicate Glass Autosampler Vials are meticulously designed for precise sample analysis in laboratories. Made from high-quality borosilicate glass, these vials offer exceptional chemical resistance and durability. They feature secure screw caps for a tight seal, ensuring sample integrity during storage and analysis. These vials are compatible with most autosamplers, providing seamless integration into laboratory workflows.

The Crimp Vial produced by Aijiren has a standard 11.6x32mm shape and is compatible with 11mm aluminum sealing caps. Hand Crimper is required for crimp sealing and Decrimper for unsealing. Aijiren provides supporting 11mm Hand Crimper and Decrimper, which are easy to operate and well sealed.

The Aijiren Storage Viale is an ideal device for general laboratory use and storage of a wide variety of samples due to its excellent sealing and chemical resistance.
In addition, chemically inert caps are suitable for most chromatography and storage applications. The highest quality PTFE or silicon septum is employed to ensure consistent quality of cleaning production and sample viale.
Flat bottom profile can maintain a stable standing state and reduce watering. Borosicate glass is used as the main material for increased corrosion resistance and heat resistance. The excellent quality of the favorable price is the one that is valued for the order and is more and more inexpensive.

9mm Screw Neck Closures-Polypropylene Screw Cap with two-layer material compound Septa can provide anti-evaporation seal. The double layer includes Silicone and PTFE. This compounded Septa can be used for multiple injections. And it is matched with a PTFE lined screw cap for organic samples. The screw cap provides an inert, air-tight seal and the use of a syringe needle to directly penetrate the sample.
