If you take 1ml of a bacterial sample and add it to 9ml of ster create a first dilution From the well mixed first dilution you take 1ml and add it to 9ml of sterile nutrient fluid and mix well creating a second dilution From the second dilution you take 1ml and add it to 9ml of sterile nutrient fluid and mix well creating a third dilution Finally you take 1 ml of the third dilution and add it to 9ml of sterile nutrient fluid mixing well and creating a fourth dilution This represents common technique for membrane filtration The third sample represents a 1 200 dilution of original bacterial sample The number of bacteria in the fourth dilution would be multiplied by 1000 none of the above
