What is a ten fold 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 starting 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.


What is the purpose of serial?

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 dilutions 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.

What is the difference between Serial and Parallel Adder?

Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.

Is there a significant difference between the various motorbike batteries?

Yes, there are differences in size, make and model of batteries- just as there are differences in engine horsepower and chassis size for bikes. Find a serial number and or chassis size on the battery or just go to a dealer and let him help you.


What is titer?

In terms of chemistry, a titer is a specific way to express a solution's concentration. The process of titer testing uses serial dilution to obtain quantitative information that is either negative or positive.


What is the major disadvantage of microbial counts performed by methods other than the serial dilution-agar plate procedure?

The total count includes dead cells as well as living cells.
