Name Testing kit for New coronavirus (2019-nCOV) IgG/IgM antibody Rapid Test WB/S/P Specifications 25 tests Introduce This kit uses the colloidal gold immunochromatographic principle to qualitatively detect novel coronavirus igg/igm antibodies in human serum, plasma, or whole blood. the sample to be tested was added to the sample hole of the test paper, and then added 2 drops of sample diluent. the igg/igm antibody in the sample combined with the recombinant new coronavirus antigen labeled with the colloidal gold on the binding pad formed complex. under the action of chromatography, it diffused forward along the nitrocellulose membrane (nc membrane). the nitrocellulose membrane was fixed with two detection lines (g line, m line) and one quality control line (c line). the g line was fixed with anti-human igg antibody for the detection of new coronavirus igg antibody; the m line was fixed with anti-human igm antibody for the detection of new coronavirus igm antibody; and the c line had quality control for the detection of the new coronavirus ig antibody. If the sample contains a new coronavirus IgG antibody, then the antibody binds to the recombinant new coronavirus antigen labeled with colloidal gold, diffuses forward, and then binds to the anti-human IgG antibody fixed on the NC membrane detection line (G line). if the sample contains a novel coronavirus igm antibody, then the antibody binds to the recombinant new coronavirus antigen labeled with colloidal gold, diffuses forward, and then binds to the anti-human igm antibody fixed on the nc membrane detection line (m line). The darker the color of the colloidal gold accumulated on the detection line, the higher the concentration of the new coronavirus antibody in the sample. To monitor the effectiveness of the test card, set up a quality control line (line C), whether there is a detection line (line T), quality control line (line C) should be color, otherwise the test results are judged invalid. Storage Stored at 4 to 30c and valid for 18 months. After the aluminum foil bag is unsealed, please use it as soon as possible. Sample 1. It is suitable for human serum, plasma and whole blood samples. 2. The samples should be used as soon as possible; if they cannot be used immediately, the serum / plasma samples should be kept at 2-8C for 5 days and -20C for long-term preservation; the whole blood samples should be placed at 2-8C to avoid hemolysis; 3.The sample contains a large amount of lipids, hemolysis or turbidity, do not use, so as not to affect the judgment of the results.

Bentonite is a highly colloidal clay mineral which gets its name from the place where its presence and usages were first discovered - Fort Benton, America. The multiple properties of bentonite namely hydration, swelling, water absorption, viscosity, thixotropy make it a multi-application product for diverse industries. Primarily two varieties of bentonite are available - sodium bentonite (high swelling, gelling and thermal durability) and calcium bentonite (more commonly available worldwide but with less swelling). Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets, and in foundry and oil - well drilling mudSodium-based bentonite of 75 mm size finds suitability in iron ore pelletisation for bonding by user industries. Bentonite has also remarkable colloidal and waterproofing properties. Chemical formula :- Al2H2Na2O13Si4 Application : Bentonite is also used in chemical, rubber, insecticide & pesticide industries and in civil construction works. Bentonite in the form of fine powder free from dirt and other foreign matter and of least swelling property is used in ceramic industry.
Konjac gum, also termed as or Konjac glucomannan, is a kind of dietary fiber which is based on konjac flour being obtained from the tuber of Amorphophallus konjac by means of drying and milling. Through further extraction and drying steps konjac flour can be processed until konjac glucomannan is obtained. Properties: - Average molecular weight of 200,000 up to 2,000,000 - Can easily be dispersed in hot or cold water - Forms a highly viscous solution with pH values between 5.0 and 7.0 - Swells slowly in water until a gel owning a high resistance to crushing and a high tensile strength is formed - Owns synergetic effects together with carrageenan, guar gum and xanthan gum - Odorless and tasteless Why caragennan needs to synergy with other gums? Carrageenan, because of its good thermal stability, high transparency and low concentration requirement when gel forming, is chosen as the main raw material to make colloidal jelly, but there are also some problems such as the gel has great brittleness, small elasticity and easy to appear liquid shrinkage etc. it is better to choose different colloids to synergy that can improve the gel properties and solve the common quality problems such as water separation of jelly. Effect: 1.Gel strength 2.Texture improver 3. Water holding capacity 4.Taste Softer and more elastic

BSD chemical ground electrode system is a new type ground system applied in locations which have higher ground requirements and are difficult to do ground work. Chemical ground electrode system is made of advanced alloy compound. Electrode surface is copper alloy to ensure the highest conductivity capability and longer service life. Conductor internal fillings contain specially made electrolytic salts which can fully absorb moisture in the air. It can release the active ions to the soil through deliquescence. It further promote conductor outer to slowly release to reduce resistance and keep a long-term resistance stability through the combination with moisture in air and soil. Compounds in conductors gradually change into colloid transparent states as time goes. Making use of conductivity property of colloid compounds, the whole system is kept at ion exchange state for a long life, thus forming ideal electrolytic ion grounding system. Ground resistance may gradually decrease after conductor internal slow-release fillings are buried and it will be stable in half a year to one year. Slow release will last as long as several years. Main connection components of BSD chemical ground electrode system are exothermically welded, removing connector loose phenomenon easily arising in other joining methods. One set, packing by sea delivery standard.

Latex is a sticky, milky colloid drawn off by making incisions in the bark of the Par rubber tree (Hevea brasiliensis) and collecting the fluid in vessels in a process called tapping. The latex then is refined into rubber ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. Concentrated Latex is derived from Field Latex and is processed using centrifuge methods. It contains 60% Dry Rubber Content (DRC). There are two main types of Concentrated Latex available in the market: High Ammonia or Standard Ammonia Concentrate (HA Latex) and Low Ammonia Concentrate (LATZ).
