Advantages Of Serial Dilution
Serial dilution is usually 1/10 dilution. Therefore after a series of dilutions, you have a logarithmic curve of concentration (log10). Basically, if diluting 1/10 and startin g off with 1 molar solution, first dilution = 0.1M, 2nd = 0.01M, 3rd = 0.001M. If making a 0.001M solution involved weighing out 0.005g of a salt for example, the error in making this solution out would be very large in comparison to weighing out 5g (1M) and diluting it 3 times by serial dilution. The benefit of it is mainly accuracy. It is very simple. You just boil the water.
Study online flashcards and notes for Serial Dilution method including Advantages of. Advantages of serial dilution. Disadvantages of serial dilution. Solutions and Dilutions. List the advantages and disadvantages of preparing a 1:1000 dilution in a single step. The advantage behind conducting a serial dilution is that there are fewer from MUS.
You boil the milk. It kills the germs. Software Karaoke Pc Full Version. Well that is an awful answer. What you do is: 1.
Using a sample of milk, tr ansfer 1ml into the first sterile water blank. Label this tube 1:10.
Mix the tube 3.Using another transfer pipette, transfer 1ml of the 1:10 tube to the next sterile blank tube. Label this tube 1:100. 4.Continue making transfers until 1:100 and 1:10000 dilutions have been made. After all dilution have been completed, transfer ½ ml from the 1:10 dilution and place it on a plate labeled 1:20. Spread the liquid across the surface of the plate with a clean spreading rod.
Continue making plates in this fashion from each of the dilution tubes until you have created four plates: 1:20, 1:200, 1:2000, 1:20000. Place the plates to be incubated. A common design for estimating the concentrations of compounds in biological samples is the serial dilution assay, in which measurements are taken at several different dilutio ns of a sample, giving several opportunities for an accurate measurement. Curren tly, serial dilution is a standard tool in the fields of toxicology and immunology. Serial dilution helps to choose a dilution which is relevant to our experiment. Often the standard which is given to you in the lab is far to strong for the experiment and it needs to be diluted.
But equally the equipment has a detection limit so we can't dilute it to much, or if it is too diluted the experiment might not work.
