What else can I help you with?
I have to prepare a 1 to 10 dilution and have a 2ml culture suspension and want to prepare a 1 to 10 dilution of the entire culture.?
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
How does one prepare a 1100 dilution?
1 part of solution A plus 99 parts solution B
What does 2 to 1 dilution mean?
A 2 to 1 dilution means that for every 2 parts of a concentrated solution or substance, there is 1 part of a diluent (such as water). This results in a total of 3 parts, with the final mixture having a concentration that is one-third of the original. For example, if you have 2 mL of a solution and add 1 mL of water, you create a 2 to 1 dilution.
How do you make a 1 to 100 dilution?
To make a 1 to 100 dilution, start by taking 1 part of the concentrated solution and add it to 99 parts of a diluent (usually water or a buffer). For example, if you use 1 mL of the concentrated solution, mix it with 99 mL of the diluent. Ensure thorough mixing to achieve a uniform dilution. This results in a final solution that is 1% of the original concentration.
What does 1 in 50 dilution mean?
A 1 in 50 dilution means that one part of a substance is mixed with 49 parts of a diluent, resulting in a total of 50 parts. This is often expressed as a ratio (1:50) or as a fraction (1/50), indicating that the original substance is present at a concentration of 2% (1 part out of 50). This type of dilution is commonly used in laboratories for preparing solutions with specific concentrations.

Definition of dilution and dilution factor?
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
To prepare 300 ml of a 115 dilution from a 13 dilution you need to add ml of the 13 dilution to ml of diluent?
33,4ml
How do you make a 1 to 5 dilution?
To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.
How does one prepare a 1100 dilution?
1 part of solution A plus 99 parts solution B
How would you prepare 20 ml of a 1 to 400 dilution?
If accuracy is not a problem the most simple way to produce 20 ml of a 1:400 dilution is to take 1:400 of 20 ml (i.e. 0.05 ml) of the original solution and add 19.95 ml of liquid. As pipettes are the most precise close to their maximum uptake volume and micro-pipettes are inherently much less precise than pipettes for larger volumes I'd do a two-step dilution. 1. step: 1.000 ml of original solution with 1 ml pipette + 4 times 4.750 ml with 5 ml pipette 2. step: 1.000 ml of solution from step 1 + 4 times 4.750 ml with 5 ml pipette.
If dilution is 4 oz of powder makes 128 gallons how much powder for 1 gallon?
0.03125 ounces.
A 4 percent solution of red blood cells is needed for diagnostic testing in the laboratory what dilution of packed red blood cells does this represent?
1:4
How do you prepare 1mM edta from 0.1M edta-Na2 solution?
You dilute it 1:10, then you take 1 part of that solution and mix it with 9 parts of the diluent. That will make the 1:100 dilution you need, incl. prevention of pipette inaccuracy.
What is the difference between 1 colon 2 and 1 slash 2 dilution?
1:2 means "1 part to 2 parts", so if the "1 part" is what you are diluting, it is actually a 1/3 dilution (one part into 3 parts total). On the other hand, 1/2 means "1 part into 2 parts total", and in the colon nomenclature that would be a 1:1 dilution.
How do you prepare 1 is to 100 dilution in small volume?
Your best bet is a serial dilution, i.e. get 2 10ml volumetric flasks and take 1ml of your solution to be diluted, and make to 10ml with solvent, mix this, then take 1ml of the resulting 10mls and dilute that to 10ml. 2x 10 times dilutions is 100x dilution. Alternatively if you have less to start with, use micro pipettes
How do you do parallel dilution?
Parallel dilution is the dilution of a solution with equal quantity of the same solvent with which the solution is made. e.g., 1mL of 100µg/ml strength aqueous solution can be diluted to 2mL of 50µg/mL strength solution by adding 1mL Water.
