It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration. Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe. Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes. It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. â?¢ Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.

As for Urine Reagent Analysis Strip Uncut Sheets , we have various parameters ranging from 1 to 12 . We can provide you strip and uncut sheet URS format with high quality and competitive price PRINCIPLE AND EXPECTED VALUES URS Ascorbic acid: This test involves decolorization of Tillmann's reagent. The presence of ascorbic acid causes the color of the test field to change from blue-green to orange. Glucose: This test is based on the enzymatic reaction that occurs between glucose oxidase, peroxidase and chromogen. Glucose if first oxidized to produce gluconic acid and hydrogen peroxide in the presence of glucose oxidase. The hydrogen peroxide reacts with potassium iodide chromogen in the presence of peroxidase. The extent to which the chromogen is oxidized determines the color which is produced, ranging from green to brown. Low amounts of glucose are normally excreted in urine.3 Glucose concentrations as low as 100 mg/dL, read at either 10 or 30 seconds, may be considered abnormal if results are consistent. At 10 seconds, results should be interpreted qualitatively. For semi-quantitative results, read at 30 seconds only. URS Bilirubin: This test is based on azo-coupling reaction of bilirubin with diazotized dichloroaniline in a strongly acidic medium. Varying bilirubin levels will produce a pinkish-tan color proportional to its concentration in urine. In normal urine, no bilirubin is detectable by even the most sensitive methods. Even trace amounts of bilirubin require further investigation. Atypical results (colors different from the negative or positive color blocks shown on the color chart) may indicate that bilirubin-derived bile pigments are present in the urine specimen, and are possibly masking the bilirubin reaction.

One Step Influenza A Test is a rapid qualitative assay that detects influenza type A (including the subtype H1N1) nucleoprotein antigen extracted from the nasal swab specimen. The device is used to aid in the diagnosis of influenza type A infection. For in vitro diagnostic use only. For professional use only. Influenza A SUMMARY Influenza (commonly known as flu) is a highly contagious, acute viral infection of the respiratory tract. It is a communicable disease that is easily transmitted through the coughing and sneezing of aerosolized droplets containing live virus. Influenza outbreaks occur each year during the autumn and winter months. There are three types of influenza viruses: A, B, and C. Only influenza A viruses are further classified by subtype on the basis of the two main surface glycoproteins hemagglutinin (HA) and neuraminidase (NA). Influenza A subtypes and B viruses are further classified by strains. Humans can be infected with influenza types A, B, and C viruses. Subtypes of influenza A that are currently circulating among people worldwide include H1N1, H1N2, and H3N2 viruses. Influenza B viruses can cause morbidity and mortality among humans, but in general are associated with less severe epidemics than influenza A viruses. Although influenza type B viruses can cause human epidemics, they have not caused pandemics. Influenza type C viruses cause mild illness in humans and do not cause epidemics or pandemics. Influenza A PRINCIPLE One Step Influenza A Test is a rapid immunochromatographic test for the visual detection of influenza type A antigen (nucleoprotein) extracted from the nasal swab specimen. The test adopts double antibody sandwich method. When the extracted specimen is added into the test device, the specimen is absorbed into the device by capillary action, mixes with antibody-dye conjugate, and flows across the membrane pre-coated with influenza type A monoclonal antibody. When the influenza type A antigen levels are at or above the target cutoff (the detection limit of the test), type A antigen in the specimen binds to the specific antibody-dye conjugate and are captured by influenza type A monoclonal antibody immobilized in the relative site of test region T of the device. This produces a colored test band in the test region. When the influenza type A antigen levels are zero or below the target cut off, there is not a visible colored band in the test region of the device. This indicates a negative result for influenza type A.
Intended Use The One Step HAV IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Hepatitis A Virus (HAV) in Whole Blood /Serum / Plasma to aid in the diagnosis of Hepatitis A Virus. Summary Hepatitis A is an acute, usually self-limiting disease of the liver caused by hepatitis A virus (HAV). HAV is transmitted from person to person, primarily by the faecal-oral route. The incidence of hepatitis A is closely related to socioeconomic development, and seroepidemiological studies show that prevalence of anti-HAV antibodies in the general population varies from 15% to close to 100% in different parts of the world. One step HAV IgG/IgM Test is a simple, visual qualitative test that detects Hepatitis A Virus antibodies in human Whole Blood /Serum / Plasma. The test is based on immunochromatography and can give a result within 15 minutes. Principle The One Step HAV IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of Hepatitis A Virus antibodies (IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing HAV recombinant envelope antigens conjugated with Colloid gold (HAV conjugates) and rabbit IgG-gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with the antibody for the detection of IgM anti-HAV, T2 band is coated with antibody for the detection of IgG anti-HAV, and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-HAV, if present in the specimen, will bind to the HAV conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a HAV IgG positive test result and suggesting a recent or repeat infection. IgM anti-HAV if present in the specimen will bind to the HAV conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a HAV IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device. Storage and Stability Store as packaged in the sealed pouch at room temperature or refrigerated (4-30 or 40-86). The test device is stable through the expiration date printed on the sealed pouch. The test must remain in the sealed pouch until use.
Syphilis Test INTRODUCTION Anti-Syphilis Test is a rapid direct binding test for the visual detection of anti-syphilis antibodies in serum as an aid in the diagnosis of syphilis infection. Test results are read visually without any instrument. It is based on the principle of double antigen sandwich immunoassay for determination of syphilis antibodies in serum. Purified recombinant syphilis antigens are employed to identify anti-Syphilis antibodies specifically. This one step test is very sensitive and only takes about 10 to 20 minutes. Syphilis Test SPECIMEN COLLECTION For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the serum from the clot. Use the serum for testing. If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen repeatedly. Syphilis Test PROCEDURE Strip 1.When you are ready to begin testing, open the sealed pouch by tearing along the notch. Remove the test from the pouch. 2. Immerse the strip into the container with the arrow end pointing towards the container. Do not immerse past the MAX (maximum) line. Take the strip out after 8-10 seconds and lay the strip flat on a clean, dry, onabsorbent surface (e.g., mouth of the serum container). 3.Wait 10-15 minutes and read result. Do not read results after 20 minutes. Cassette 1. Open a pouch containing a cassette, lay the cassette. 2. Using the plastic pipettor provided, draw about 2-3 drops (100mL) the sample into the sample well of the cassette. 3. Read results within 10-15 minutes. Do not read results after 20 minutes. INTERPRETATION OF RESULTS Negative: Only one pink band appears on test region of the Cassette. This indicates that there is no detectable Anti-Syphilis in the serum. Positive: Two pink bands appear on test region of the Cassette. This indicates that the specimen contains detectable amount of Anti-Syphilis. Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device. Syphilis Test PRECAUTION: 1. Must use fresh specimen and avoid repetitive freezing, the result will be invalid 2. Use it before expiry date. 3.The package of kit should not be opened until it reaches the room temperature if it taken out from the refrigerator. 4 .Old Serum can not be used. If the serum is thick, it can be used only after being separated. Syphilis Test LIMITATIONS The test is for in-vitro diagnostic use only.
