The sperm density analyzer Coca United States by the Italian company produced animal breeding. Semen is used to determine the concentration of livestock in the 470-570nm filter was measured. Before each measurement instrument will automatically adjust 0, so no manual. 
 Sperm densimeter shows the concentration of undiluted transmission coefficient of mirrors, built-in micro-processing the results of the special reference to transmission coefficient table of six parties after the 10 units per milliliter to display the control reading, the following approximate range. 

 Sperm density instrument operation manual: 

 Step one: Use diluted solution to zero the instrument 
 1, according to ON key to turn on the instrument, there is ... ... shows that the instrument has been opened; 
 2, the test bottle lid open (when the instrument when not in use, the test bottle lid to keep covered); 
 3, to test the bottle into 10 ml of diluent (distilled water with a good powder and diluted semen dilution); 
 4, with a clean paper towel to wipe the outside of the test level, and then insert the instrument in the test hole; 
 5, the test bottle lid; 
 6, according to ZERO button, wait for instrument display -0-- (Note: the automatic calibration of the instrument); 


 Step Two: Measure the density of sperm 
 1, the test bottle lid open, it is not necessary to test the bottle out from the test hole; 
 2, with a syringe or pipette to the test injection of 0.2 ml bottle of fresh semen collected just; 
 3, the suction through the pipette to mix the semen and diluent; 
 4, the test bottle lid; 
 5, according to READ / DIRECT button and wait for a transmission coefficient appears on the display, for example, 0.333; 
 6, light transmission coefficient of this record, through conversion to calculate the density of the semen (the transmission coefficient of this instrument is from 0-2.0); generally the number of sperm semen samples collected from 8 10 to 800 million range, that is, transmission factors ranging from 0.07 to 0.71 range; 
 7, and sometimes exceed the maximum light transmittance measured coefficient of 2.0, the proof of the concentration of sperm in semen is too high or too many impurities (such as white blood cells, kidney epithelial cells fall off too much, when the semen collected dust pollution) caused by the original semen please 1600 times by microscopic examination qualified, qualified semen diluted with the 1:2 or 1:3, re-measurement. 


 Step three: equipment storage after use 
 1, stop using this instrument will automatically turn off after 10 minutes; 
 2, measured after the completion of all the semen samples, the test bottle out from the test hole to test the protective covering over the hole; 
 3 instrument with a dry paper towel to wipe clean, back in the box; 
 4, the test bottle thoroughly washed back into the hole in their box; 
 5, the determination of the light bulb in the dirty hole, use a cotton swab stick with alcohol gently wipe clean; 
 6, when the instrument's LED LCD screen appears "V" on behalf of voltage instability, replace the battery. 

 Head of the semen collected from the calculation were: 
 The total number of sperm = V 
 Sperm motility = M 
 The number of sperm required per insemination (40 million active sperm) = S 
 Sperm density = P 

 The first number of copies = V * P * M / S 

 For example: When the reading of 0.36, the look-up table shows P = 4.03 billion / ml V = 250 毫升 M = 70% S = 40 亿 

 Head of shares = 250 * 4.03 * 70% / 40 = 17.6 







 Italy sperm density instrument, is more advanced artificial insemination of common laboratory equipment, each must contain a certain amount of semen of sperm to ensure the success rate of artificial insemination, and the boar of the variety, structure, time and so different, each collected Pure boar semen volume and quality are different, so that each pure boar semen can be collected in the preparation of several diluted semen, we must know the density of pure boar sperm, through the transmittance of different programs and computer chips calculations, sperm density gauge can quickly show boar semen sperm density, which is accurate, convenient and efficient preparation of diluted semen, sperm density gauge is a good helper for artificial insemination laboratory. 

 Italy sperm density instrument configuration and parameters: 
 1, host 1. Dimensions: length 180mm, width 83mm, high 46mm. 
 2, glass color absorption column 2 (wide glass color absorption column is specifically designed for the sperm density instrument design accurate and has patented), import the original cloth 2. 
 3, a portable suitcase. 
 4, 1 set of operating instructions (sperm density instrument table.) 
 5, 9V battery 1. 
 6, the measurement results accuracy greater than 98%. 
 7, no regular or repetitive control debugging control debugging. (With automatic debugging) 
 8, measuring animal species: pigs 
 9, non-disposable supplies and cost savings than similar products. 
 10, LED LCD, low-power or voltage automatic alarm function ("V" character LCD display this symbol is lack of power or voltage, replace the battery.) 
 11, wavelength range: wavelength 470-570 nm (with automatic adjustment based on the measured wavelength of animals function). 
 12, automatic shutdown: Stop using the equipment after 10 minutes automatic shutdown. 
 13, the operating environment: flat on the clean room equipment, operating temperature range of "-5 degrees -50 degrees." 
 14, sperm density gauge does not require preheating. 
 15, the results show time, 1 second, display the results, turn the blank control, the results of measurements show that for every 1 second after the step button displays the results or data. 
 16, the total weight of the host portable suitcase plus 1.5kg, Weight 290g. 
 17, LED light transmission coefficient of liquid crystal display (refer to table that is derived sperm density) 
 18, determination of time of 0.5 seconds to reading (reading transmission coefficient). 
 19, transmission coefficient measuring range :0-2 .0 
 20, the control solution: 10ml of semen dilution (double distilled water or double distilled water with a mixture of semen dilution dilution). 
 21, the test base price (sample): 0.2ml of fresh semen collected from the original. 
 22, the instrument has an automatic effect positive function.
