What is the best way to remove a portion of the material from the vial, in order to prepare a standard from Product 34044, Tiamulin?
Tiamulin is a viscous liquid at room temperature, so it is a little difficult to work with. The kind of vial that is used for Product 34044-100MG-R is what Sigma-Aldrich Germany typically uses for amounts of about 10 mg to 100 mg. Tiamulin does not have a good chromophore, so we don't have an extinction coefficient for it; that is, if there were a chromophore, one might be able to quantitate it by measuring the UV absorbance of a solution.Here are our recommendations:1. Heat the vial up to 50-60°C. This will significantly reduce the viscosity of the Tiamulin.2. If there is material visible in the cap of the vial, spin it down using a small benchtop centrifuge for a few seconds. Briefly warm back up to 50-60°C if the vial cools down significantly during centrifugation.3. Using a pipetter, carefully transfer about 10 microliters of the warm liquid into a tared vial on a balance.4. Obtain an accurate weight, and use that in your calculations.As the material is needed, the vial can be heated several times to 50-60°C, without harming it. The 100 mg is roughly 100 microliters, so following the recommendations above, you should be able to obtain about 10 samples from the vial of 34044-100MG-R.
