With the Aijiren COD tube test, each user can easily perform highly sensitive and accurate water detection. The time required for the measurement process is greatly shortened, especially for standard analysis and series measurement, while greatly reducing the workload. The COD test tube contains a precise dose of reagent. Therefore, excessive chemical stocks are avoided and work safety is improved.
When using COD test tubes, we usually inject the sample to be tested into the test tube and shake the tube vigorously to suspend all the sediment. Remove the cap of the COD test tube and add 2 mL of sample using a pipette.
When filtering samples choose right membrane syringe filter is very important. If you choose wrong syringe filters your chromatogrpahy instrument will be failed, which can waste a lot of time and money since liquids are normally very expensive. Aijiren provides cost-effective non-sterile and individual packed sterile syringe filters from Nylon, PES, PP, PTFE, PVDF, RC, etc. welcome to inquiry E-mail:firstname.lastname@example.org whatsapp:+8618336073276
0.45um Syringe filters are normally used in scientific research laboratories to remove certain sized particles or bacteria from certain volume of liquid or gas prior to analysis or cell culture. 0.45um Syringe filters are popularly used in HPLC analysis.
8-425 polypropylene screw finished cap with PTFE and silicone septa for chromatography autosampler vial, this screw cap can supply solid and hollow. Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Screw cap are available in 8-425 screw cap, 9mm screw cap, 10-425 cap, 13-425 cap and 24-400 cap.
The syringe filters produced by Aijiren are of high quality, packaged and sold at reasonable prices. They are suitable for most major membrane materials, including nylon, PTFE, PES, MCE, PVDF, CA, PP and GF. They are available in 13mm, 17mm, 25mm and 30mm formats, and use a pure polypropylene shell.
Aijiren storage vials have excellent sealability and chemical resistance, and are ideal equipment for general laboratory use and various sample storage. In addition, chemically inert lids are ideal for most chromatography and storage applications. Use top PTFE or silicone septa to ensure clean production and stable quality of sample bottles.
The COD Test Tube produced by Aijiren is often used for chemical oxygen demand (COD) testing, and COD testing uses a specific oxidant to oxidize the substances (including organics) in the water sample. As the temperature and time decrease, the test requires This method is often widely used as a measure of organic pollutants.
The COD Test Tube produced by Aijiren is often used for water quality testing. In order to adapt to different models and brands of machines, Aijiren has launched a multi-size COD Test Tube. The caliber is a uniform 16mm, but the sizes are 9ml, 10ml, 12ml and 15ml. The 9ml COD Test Tube has a flat bottom, the 10ml COD Test Tube has a flat bottom and a round bottom, and the 12ml and 15ml COD Test Tubes have a round bottom.
The Screw Top Vials produced by Aijiren are available in three different calibers, 8mm, 9mm and 10mm. The matching PP Screw Caps are made of high-quality polypropylene materials. If the number of samples to be tested is small, it can also be used with micro-insert. Bottles with different calibers have different matching micro-inserts.
Aijiren Storage vial is an ideal device for general laboratory use and storage of diverse samples due to excellent sealability and chemical tolerance. Aijiren sample storage vials have excellent sealability and chemical resistance, and are ideal equipment for general laboratory use and various sample storage. Because of its high tightness, the screw thread makes the cap and vial tightly fit. Septa can fill the gap between Vial and Cap to prevent the sample from leaking out.
There are screw top autosampler vial, snap Top HPLC vial and glass storage vial. All of those glass vial are often needed in laboratory. The glass vial can supply in Amber and Clear color. Borosilicate 3.3 Glass material made the Glass vial.
9mm screw autosampler vial with PP screw cap and PTFE septa is packaged in one box. This HPLC vial package can also be printed your logo on it. Do you want need this package?
The Chemical Oxygen Demand Tubes supplier region is the second-largest market for chemical oxygen generators.Aijiren is the leading supplier of Chemical Oxygen Demand Tubes from China.
Aijiren can supply glass vial, such as autosampler vial, screw top HPLC vial, snap top glass vial and crimp finished headspace vial. You can also get micro-vial and micro-insert in aijiren shop. The micro-vial and micro-insert is used for chromatography system, too.
2mL of water or wastewater sample is added to a Chemical Oxygen Demand Tubes containing the digestion reagent and a catalyst. Aijiren is the leading supplier of Chemical Oxygen Demand Tubes from China.
9mm screw autosampler vial with micro-insert for chromatography analysis has been widely recognized. This micro-insert has different shape. Cone bottom and Flat bottom micro-insert are very common. You also saw the micro-insert with spring support.
Wholesales Chemical Oxygen Demand Tubes with a cap from China Aijiren Tech.Aijiren is the leading supplier of Chemical Oxygen Demand Tubes from China.
Micro-vial volume is 0.3ml. this micro-vial is used for chromatography instrument. There are some expensive sample to analysis. To the needle inject the sample, so this vial is needed. Compared with micro-insert, micro-insert is more expensive. But the micro-vial is compatible with most instrument.
The syringe filter produced by Aijiren is often used to filter impurities in the reagents to be tested. After the impurities are filtered, the reagents can be sucked into the autosampler. If the syringe filter is not used, it may cause problems such as clogging the needle hole with impurities in the reagent.
