Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO (Master liquid concentration mg/mL)，Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation：Take μL DMSO master liquid, next add μL PEG300， mix and clarify, next add μL Tween 80，mix and clarify, next add μL ddH₂O, mix and clarify.

Note:

Be sure to add the solvent(s) in order. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Molecular Weight

Molarity Calculator allows you to calculate the

Mass of a compound required to prepare a solution of known volume and concentration
Volume of solution required to dissolve a compound of known mass to a desired concentration
Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
