1.5ml 9mm Screw Neck Vial for automatic samplers is made of low metal type 33 and 51 COE borate glass to prevent sample instability or leaching. By selecting the cap and pad, we provide the best sealing solution for the sample.

All Aijiren bottles have permanent white enamel scales for volume measurement; white identification boxes for marking or coding.
All Aijiren media bottles include non-drip sealing rings and standard blue polypropylene (GL45) sealing caps.

These glass culture tubes These glass culture tubes feature a durable construction to withstand the rigors of laboratory use. The screw cap provides an airtight seal to prevent sample contamination and evaporation. The clear glass material allows for easy visual inspection of the sample. The tubes are compatible with common laboratory techniques such as centrifugation, incubation and sample storage. They may also include graduation marks for accurate volume measurement and convenient sample identification.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. t. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

1.5ml/2mlSnap autosampler borosilicate glass vial refers to a type of vial commonly used in laboratory settings for sample storage and analysis.
Borosilicate glass is chosen for its excellent resistance to thermal shock, chemical durability, and low contamination potential.
The term “Snap autosampler” typically refers to an automated instrument used in analytical chemistry, specifically in chromatography.
It is designed to automatically inject samples into the chromatographic system for analysis.
The vials used with such autosamplers need to be compatible with the instrument’s design and specifications.

The MCE membrane filter provides researchers with the lowest combined filter. Due to their extremely low binding characteristics, these filters provide higher throughput than competing products and reduce filter replacement when filtering protein solutions.

11mm Snap Closures are an extension of the crimp cap sealing system. Stretch the plastic cover on the edge of the 11mm Snap Vial, and form a seal by squeezing the Septa between the glass and the PP Cap. The advantage of the plastic snap cap is that it can be assembled without tools. 11mm Snap Closures is a simple sealing system. If 11mm Snap Closures have a very tight fit, they are difficult to apply and may crack. If the fit is too loose and the seal is not good, Septa may fall off.

Equipped with Silicone/PTFE Septa, and can also be used with slit septa. Usually the available cap color is silver, but other special colors can also be produced accordingly. There is a 9.5mm center hole in the center of the cap for automatic sample injection.

The sterile syringe filter provided by Aijiren has a cellulose acetate or PES filter membrane. A sterile membrane with a pore size of 0.2um is an ideal material for sterilization and filtration, while a pore size of 0.45¦Ìm can be used for clarification. The sterile needle filter is sterilized by gamma radiation, which avoids the toxic residue caused by other sterilization methods

The 9mm screw cap produced by Aijiren has a center hole to facilitate the sampling of the injection needle of the autosampler. The injection needle will penetrate the septa and enter the interior of the vial for extraction. The thread pattern of the 9mm screw cap fits closely with the vial. Septa is slightly squeezed between the cap and vial to fill the gap, so the sealing is extremely high.

13 mm Syringe Filters: For sample volumes <10 mL range; Ideal choice for most applications; Holdup (dead) volume is <15 ul; Female inlet luer lock; Maximum operation pressure <15 bar; Bubble point: Hydrophilic 2-3 bar; Hydrophobic 1-1.2 bar.

Aijiren is a manufacturing enterprise with its own production machines and production lines. Customers can customize Vial and Closures according to their own needs, such as logo customization, capacity selection, solid or center hole Cap, septa selection, etc. And so on, because of these exclusive customized services, Aijiren can become a professional and satisfied customer supplier of chromatography consumables.

Syringe filter is a small, disposable device used for filtering liquids or gases.It consists of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end, which allows it to be attached to a syringe or other fluid delivery system.
Syringe filters are commonly used in laboratory and research settings to remove particles, microorganisms, or other impurities from samples before analysis or further processing. The membrane filter in a syringe filter acts as a barrier, allowing only the desired components of the sample to pass through while retaining any larger particles or contaminants.
The choice of membrane material depends on the nature of the sample and the substances to be filtered.

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.

2mL Amber Glass Screw Top Autosampler Vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Amber Glass Screw Top Autosampler Vials, the product material is of paramount importance.
