SUMMARY Bilirubin: This test is based on the coupling of bilirubin with a diazotized dichloroaniline in a strongly acid medium. The colors range from light tan to reddish-brown. Ketone: This test is based on the reaction of acetoacetic acid with sodium nitroprusside in a strongly basic medium. The colors range from beige or buff-pink color for a Negative reading to pink and pink-purple for a Positive reading. Specific Gravity: This test is based on the apparent pKa change of certain pretreated polyelectrolytes in relation to the ionic concentration. In the presence of an indicator, the colors range from dark blue or blue-green in urine of low ionic concentration to green and yellow-green in urine of higher ionic concentration. Blood: This test is based on the pseudoperoxidase action of hemoglobin and erythrocytes which catalyzes the reaction of 3,3, 5, 5-tetramethyl-benzidine and buffered organic peroxide. The resulting colors range from orange to yellow-green and dark green. Very high blood concentration may cause the color development to continue to dark blue. pH: This test is based on the well known double pH indicator method, where bromothymol blue and methyl red give distinguishable colors over the pH range of 5-9. The colors range from red-orange to yellow and yellow-green to blue-green. Protein: This test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a �??Negative�?? reaction to yellow-green and green to blue-green for a �??Positive�?? reaction. Urobilinogen: This test is based on a modified Ehrlich reaction in which p-diethylaminobenzaldehyde reacts with urobilinogen in a strongly acid medium. Colors range from light pink to bright magenta. Nitrite: This test depends on the conversion of nitrate to nitrite by the action of Gram-negative bacteria in the urine. The nitrite reacts with p-arsanilic acid to from a diazonium compound in an acid medium. The diazonium compound in turn couples with 1,2,3,4-tetrahydrobenzo(h) quinolin to produce a pink color. Leukocytes: This test is based on the action of esterase present in leukocytes, which catalyzes the hydrolysis of an indoxyl ester derivative. The indoxyl ester liberated reacts with a diazonium salt to produce a beige-pink to purple color. Ascorbic Acid: The composition comprises of a complex chelating agent with a polyvalent metal ion in its higher state and an indicator dye that can reacts with the metal ion in its lower state to produce a color change from blue-green to yellow.
General Information The Urinalysis Reagent Strips (Urine) are firm plastic strips onto which several separate reagent areas are affixed. The test is for the detection of one or more of the following analytes in urine: Ascorbic acid, Glucose, Bilirubin, Ketone (Acetoacetic acid), Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite , Leukocytes and so on.
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 Tillmannâ??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 of the serious problems of natural environment protection during oil and gas production is liquidation ground by oil pollution. Oil and mineral oils disturbed ecological state of top-soils as a whole deformed biocoenosis structure. In results of damages (oil) pipe lines, oil-processing and petroleum distillating plants a great deal of oil and oil production comes in ground. Cleaning and reconstruction of in ecocatastrophe region realizes properly polluted ground impressments from pollution place with its posterior cleaning by chemical and biological methods or its, immediately contiguous to technological object also to environment air and burial on special firing range. Elimination the oil flood permits to greatly improve sanitary state not only on territories water. Oil hydrocarbons decomposition intensity and character in ground mainly defined by functional activity hydrocarbono-xidizing bacteria (HOB) capable to assimilate oil as a single carbon spring. Method biological or polluted burial on special firing range was not find wide application. Since the first method is virtual during of the ground pollution more than 5-10%. And second method is not widespread for the reason of loose huge number of grounds. During last years new compositional structure are developed by “Karvan L” company staff on the basis of surfactant species “LD500IF”. The reagent successfully passed work bench measurements on hydro-cyclone units and effectiveness of the feagent is 98 -99 % during expenditure norm 20-25 mg/l.

How much is 40 billion yuan? I believe that most people, like me, are a relatively abstract concept, simply a big number. Suppose you win 5 million prizes in the lottery, and you win 8,000 times. If it is used to buy in vitro diagnostic reagents, how much can you buy? How much serum separation gel can be bought for 40 billion? Usually the price of domestic serum separation gel is tens to one or two hundred per kilogram. We calculate at 100 yuan per kilogram, and 40 billion can buy 400 million kilograms of separation gel. Separating glue is generally 25 kg per barrel, and the barrel is about half a meter high. These barrels of separating glue can be connected to 8 million meters, which is a thousand times the height of Mount Everest and 800 times the depth of the Mariana Trench, the deepest part of the earth. How much can be done if these separating glues are added to the vacuum blood collection tube? Generally, coagulation tubes or anticoagulation tubes with a blood collection volume of 3-5mL add 0.8-1.2g of separation gel. We calculate by adding 1g separation gel per tube. These separation gels can be made into 400 billion blood collection tubes with a tube length of 10 cm. , Then these blood collection tubes can be connected from the earth to the moon back and forth 50 times, and can also go around the earth's equator 1,000 times, and weave a scarf for the earth. How much heparin can be bought for 40 billion? If you feel that the separation glue is not intuitive enough, then use 40 billion to buy heparin. The price of this is much higher. We calculate at a price of about 100 yuan per gram. The money can buy 400,000 kilograms of heparin. On average, 1300 pig small intestines can extract 1 kilogram of heparin. This heparin needs to sacrifice 520 million pigs, which is 4.3 of the total population of Japan. It is 1.6 times the total population of the United States and 70% of the entire European population! My goodness, if so many pig small intestines are used to extract heparin, the remaining pork is even more unimaginable. Of course, we canâ??t really spend 40 billion to buy separation gel or heparin. There are many in vitro diagnostic reagents that are more expensive than heparin, such as chemiluminescence reagent acridinium ester and enzyme preparations, antigen and antibody protein preparations, and the price is even higher than that of heparin. The milligram calculation is far more than that of gold, but usually the amount of these reagents is not much at one time, so the entire supporting products involved are also many. Desheng is a manufacturer engaged in the research and development of blood testing and virus testing related reagents, and welcomes the cooperation of in vitro diagnostic reagent companies.
