AJRC-20W Hand Crimper for 20mm Crimp Caps seals, economical supplier

2ml lab autosampler vial is a small container typically used in laboratory settings to store and transport samples for analysis.
Autosampler vials are designed to be compatible with automatic sampling systems or instruments known as autosamplers.
The capacity of a 2ml autosampler vial refers to its volume, and it can hold up to 2 milliliters (2 ml) of liquid or sample.
These vials are commonly made of glass or high-quality plastic materials such as polypropylene or polymethylpentene (PMP).
The choice of material depends on the specific application and compatibility requirements.

Suitable for 11mm 2ml Crimp Neck Vials & 20mm Headspace GC Vials
Caps Material: Aluminum
Use Together with PTFE/Silicone Septa or Rubber Stopper
Color: Metal Silver
Vial Septa & Rubber Stopper and Crimpers are also Provided

Chemical oxygen demand is a vital test for assessing the quality of effluents and waste waters prior to discharge. The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand. This is because the removal of oxygen from the natural water reduces its ability to sustain aquatic life. The COD test is therefore performed as routine in laboratories of water utilities and industrial companies.

A handy and inexpensive vial/closure combination for uncritical analyses.
Star-shaped diaphragm enables easy penetration of the PE-Plug.
Recommended for HPLC usage.
For the 1ml Shell Vials a plug with and one without insertion barrier for Micro-Inserts is available. The one without barrier shows a better valve effect with regard to the formation of a vacuum.
Shell vials and the appropriate plugs can also be supplied as a 2in1 KIT.

But for autosamplers with blunt autosampler needles, Aijiren still recommends buying septa with pre-slit, because this can prevent the septa from being pushed into the vial by the autosampler and contaminate the sample. Septa with pre-slit can complete the function of guiding the automatic injection needle.

A transparent glass vial made of type 1 borosilicate glass with a 20mm crimp sealing surface, suitable for most headspace autosamplers, this is the headspace bottle produced by Aijiren. When using the headspace autosampler, the robotic arm that lifts the robotic arm from the tray makes it easier to handle round-bottomed sample vials.

Chromatography autosampler 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. Its basic requirements are accurate volume, ability to withstand a certain pressure, good sealing performance, and no adsorption to samples.

Screw glass vial refers to a type of container made of glass that has a screw-on cap or closure mechanism. These vials are commonly used for storing and transporting various substances, such as liquids, powders, or small solid samples, in scientific, pharmaceutical, and industrial applications.
The screw-on cap ensures a secure and airtight seal, preventing the contents of the vial from leaking or being contaminated. This feature is particularly important when storing sensitive or valuable substances that require protection from moisture, air, or other external factors.

Aijiren has its own bottle manufacturing plant. Aijiren strictly controls the manufacture of products and can ensure that the specifications of the 9mm screw neck vials in the same batch are exactly the same. Aijiren also offers customized services. You can add your own logo to Via and specify the color of the cap.

Aijiren¡¯s 1.5ml amber vial production plant has a professional production line and production team, and has been strictly checking the product quality during the production process. If any 1.5ml amber vial that does not meet the standard will be immediately eliminated, it is precisely because of Aijiren¡¯s strict product Controlling talents has created Aijiren’s brand effect today and has become a well-known supplier of chromatography consumables in China.

Aijiren’s syringe filters with nylon membranes are compatible with a wide range of solvents, making them ideal for fast filtration of most aqueous and organic solutions. Therefore, when a mixture of sample aqueous solution and organic solvent passes through nylon membrane, fine droplets of extractor solvent accumulate and are separated from the sample aqueous solution. Using this simple method, the total extraction time is only 3-4 minutes; It is environmentally friendly, has no centrifugal effect, provides a higher sample purification rate by filtering receptor phases, and filtering reagents ensures reduced impurities and protects the color column.

A headspace vial is used in the process of top – gas chromatography. The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability.

HPLC Vial 10-425 1.5ml Screw Vial. The wide open vial has a larger target area to make it easier to prepare the sample and to reduce the possibility of the needle bending or bending during sampling. 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.

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.

Aijiren Syringe Filters is a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples. Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even sterilization.

The strict quality assurance of Crimp Top HPLC Vial produced by Aijiren provides dimensional consistency between batches, and the optional ceramic writing point with filling marks on the vial is certified and fully compatible with the autosampler. At the same time, Aijiren Good quality control has been achieved, including height, diameter, bottom, thickness and neck/thread, cleanliness.

COD reagent vial refers to a specific type of vial used in chemical analysis for measuring the chemical oxygen demand (COD) of a water sample. COD is a measure of the amount of oxygen required to chemically oxidize the organic and inorganic compounds present in a water sample.
The COD reagent vial contains the necessary chemicals and reagents to facilitate the oxidation reaction. It typically includes a mixture of strong oxidizing agents, such as potassium dichromate or potassium permanganate, along with other chemicals that help initiate and accelerate the oxidation process.

Open COD test tube, hold it at an angle and slowly add
2.0 mL of the pretreated sample solution from the reaction tube without mixing so that two separate layers
are formed.
Screw cap securely on to test tube, hold tube by the cap, place tube into the safety bottle and shake
(Caution, test tube becomes hot). Place tube into the heating block. Start heating programme.
After 2 h remove test tube from heating block, allow to cool down to room temperature and shake gently
several times.
Clean outside of test tube and measure.
Adjust photometer to zero by using blank value “NULL”
