PTFE Silicone Septum for Headspace Vials

Aijiren’s 9mm HPLC Vial is packaged in 2-in-1, and vial uses boxes for packaging. Customers can choose cartons and plastic boxes for packaging, 100pcs/box. The cap is packed in plastic sealed bags, 100 pcs/pack. Aijiren will use a carton for packaging on the outside, and then use plastic film to wrap the carton to prevent moisture and moisture.

Vial crimper is ideal for small batch capping operations and sample preparation operations. Designed for laboratory use with good chemical resistant surface coating, the manual capper is widely used for laboratory headspace sample vial crimping.

PVDF Syringe filter has many advantages. PVDF film has high mechanical strength, is not easy to break or curl; it has the advantages of low background, wide solvent compatibility, and excellent coloring ability; in addition, PVDF film can be tested repeatedly after proper treatment. The pore size of PVDF membrane is 0.22¦Ìm and 0.45¦Ìm. 0.22¦Ìm is suitable for proteins with molecular weight less than 20kDa, which can effectively reduce the leakage of small molecular weight proteins. Compared with 0.45¦Ìm PVDF membrane, it has higher protein adsorption rate and protein sequencing yield. For example, the adsorption capacity of insulin and BSA are 1.64 times and 1.58 times that of the commonly used 0.45¦Ìm PVDF membrane, respectively.

Opening caps with septa refers to the process of removing the cap from a vial that is equipped with a septum. This is typically done in laboratory settings when accessing the contents of the vial for analysis or other purposes.It’s important to perform these steps carefully and gently to avoid damaging the vial or septum and to maintain the integrity of the sample inside.

Standard GC, HPLC sample vial, small caliber, 8-425 standard threaded mouth, can be used for autosampler and sample storage. It can be used with 8-425 screw cap septum.
8-425 Autosampler Vial, often used in conjunction with Shimadzu, Spectrophysics, Varian, and other autosamplers. The vial is made of colorless Class 1 Type A or Amber Class 1 Type B borosilicate glass , And attached with a writable label for sample identification.
The vial cap is made of high-quality polypropylene, with precise manufacturing tolerances and a controllable manufacturing environment. The gasket is made of the highest quality PTFE/silicone to ensure the high efficiency of the function.

Aijiren has been producing 2ml glass autosampler vial since 2009. The glass vials we produce are widely used all over the world. For more than ten years, our customers are in more than 70 countries and regions. Our 2mlvial is also well received by customers. Aijiren’s customer service and product quality are among the best in laboratory consumables.

The HPLC Syringe Filter provides efficient filtration of samples in high-performance liquid chromatography (HPLC) applications. These filters are designed to remove particulate matter, contaminants, and debris from samples, ensuring clean and reliable results. With precise pore sizes and high flow rates, they enable rapid and efficient filtration without sample loss.

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.

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.

All of Aijiren 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.

Screw cap vials are available with either an open hole for autosampler use and standard addition or a solid top for sample storage. One-piece polypropylene caps and membranes are also available. These pierceable screw caps are designed for single use and reduce sample preparation time by eliminating the need to assemble the cap and liner.

Autosampler vials are available in a variety of sizes, with 2 mL vials being the most common size. During the injection process, the autosampler needle pierces the cap and extracts the desired amount of analyte from the vial. There are different types of vials for chromatography applications.

The 20mm Crimp Top Caps produced by Aijiren have a diameter of 20mm and a center hole with a diameter of 9.5mm. The color is the silver color of aluminum itself, which is very modern and beautiful. The matched septa are all 20*3mm, and the double-sided synthetic septa ensures the sealing.

10-425 Wide-opening vials provide an increased target area for easier sample preparation and to reduce the chance of bent or broken needles during sampling,10-425 Vials are manufactured of Clear, Type 1 Class A or Amber, Type 1 Class B borosilicate glass.

8-425 HPLC Vials is a GC and HPLC standard sample bottle, small caliber, 8-425 standard thread, suitable for autosampler and sample storage. It can be used with matching septa. The 8-425 autosampler vial is always suitable for Shimadzu, Spectra-Physics, Varian, and other autosamplers. It is a popular product of Aijiren, and it can be customized whether to add a writing area or a scale.
