Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.
We have strong sintered AlNiCo permanent magnet production scale, can produce the performance of Alnico2-8 grades. And annual output nearly 800 tons. AlNiCo magnet is suitable for producing complex, light, thin, and small products, and is widely used in instrumentation, communications, magnetoelectric switches, and various sensors. AlNiCo products are mainly used in automotive parts, instrumentation, electroacoustics, motors, nuclear power, teaching, aerospace and other fields. It has the characteristics of low temperature coefficient, high temperature resistance, humidity resistance, not easy to oxidize and good working stability.

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.
PRINCIPLE Progesterone (P4) is a kind of steroid hormone. The concentration change of P4 in milk is one specific characteristic indicating the activities of cow ovary. It plays an important role in the process of maternal reproduction and maintaining pregnancy. Therefore, it can be monitoring cow reproductive activity by detecting the concentration of P4. P4 concentration has different characteristic changes as the cow's stage of reproductive physiology, through to detect the progesterone levels can make an accurate diagnosis of cow in early pregnancy. PRODUCT FEATURES The strip can be used for diagnosis of cow early pregnancy, which is of high accuracy, easy operation, rapid and normal temperature storage, easy to carry, harmless to maternal and fetal safety. THE SCOPE OF USE The test is mainly suitable for dairy and beef cattle early pregnancy diagnosis, as well as to guide timely artificial insemination. THE BEST USE DATE Cow's estrus cycle is 21 days. There are individual differences in 18 to 24 days commonly, it is suggested to perform the test the 18th days after mating. Perform the test once every day for 5 continuous days; even if one negative result appears during the five days, which indicates the cow is not pregnant and P4 is at the lowest level at this moment. In this case, it was suggested to have the dairy cow mated in time; that should improve the conception rate. If positive results show for all 5 days tests, it indicates the cow is in pregnancy, and it should get careful nursing and gestation management. Another test method is to closely observe the cow rutting performance from 18 days after mating, if it was in rutting performance the detection should do immediately; for those that have no heat after mating to do a test on the 24th day. SPECIMEN COLLECTION 1.Milk sample: cleaning teats before take the milk, abandon to the first three milk, then collect milk in the bottle, take 1 ml in the test tube, placed the centrifuge10000 rpm for 10 minutes, in vitro milk sample was divided into three layers, using straws inserted in the underlying absorbing liquid cream and set aside. 2.Saliva: from the mouth collecting saliva for 3 to 5 ml placed the centrifuge 1500-2000 rpm for 5 minutes, take supernatant on standby. 3.The galley proof: from the hair root galley proof according to take 10 mg in the extracting pipe, add 3 ml anhydrous ethanol soak vortex shock 5 minutes after 2-3 hours, placed 3000 rpm centrifuge for 5 minutes, drain on ethanol solution 1 ml into glass dish, in 70-80 �?? oven dry reoccupy after 1 ml PBS dilution.

Home Menopause Test Strip is an in vitro diagnostic (IVD) qualitative test for rapid detection of human Follicle Stimulating Hormone (FSH) in urine at a sensitivity of 25mIU/ml. SUMMARY AND EXPLANATION OF THE TEST Follicle Stimulating Hormone (FSH) is a peptide hormone produced in the pituitary gland of the brain. It is normally present in the blood or urine varying in concentration with the stage of the menstrual cycle. When estrogen levels drop, FSH is released from the pituitary gland indicating that either a woman in mid-menstrual cycle or the onset of perimenopause. During early menopause, changes take place in the balance of hormones that regulate and control menstrual cycles. As a woman grows older and passes out of childbearing stage of life, the ovaries gradually make less of the hormone estrogen and FSH increases.FSH normally regulates the growth and development of an egg. Once this part of the monthly cycle is complete, FSH production is stopped and it returns to normal. As the body decreases estrogen production with age, more FSH is made. Over time these hormone changes cause menstrual periods to stop completely and "menopause" has occurred. The slow change in ovary function can happen between 2 and 10 years before the final period. This early stage before menopause is called perimenopause. During this stage, the levels of FSH may rise to positive levels and slowly return to normal, causing irregular or missed periods. The testing for FSH should be performed twice to help identify the levels of FSH throughout a menstrual cycle. PRECAUTION 1. For in vitro diagnostic use only. 2. Do not use after expiration date. 3. Test device should remain sealed until ready for use. Do not use if pouch is damaged or opened. 4. Read this instruction carefully before performing the test. 5. Do not re-use the test device. 6.

AMP INTENDED USE The AMP Gold Rapid Screen Test is a qualitative competitive binding immunoassay for determination of Amphetamine in urine. AMP PRINCIPLE The Amp Gold Rapid Screen Test is a chromatographic absorbent device in which drug or drug metabolites in a sample compete with drug antigen immobilized on a porous membrane support for limited antibody sites. Labeled antibody-dye conjugate mixes with sample specimen and binds to the free drug presented in sample forming an antibody-antigen complex. This complex prevents the formation of pink color bands in the test zone immobilized antigen conjugate when the drug is presented in the sample urine above the detection levels (1000ng/ml for Amphetamine). Unbound dye conjugate binds to the reagent in the control zone and produces a pink-rose color band, demonstrating that the reagents and device are functioning correctly. A negative specimen produces two distinct color bands, one for the control in the �¢??C�¢?? zone and one for Amphetamine in the �¢??T�¢?? zone. AMP REAGENTS AND MATERIALS PROVIDED 1.
