Bottles - VWR

Plastic bottles are flexible and perform well for squeezing functions, at low temperatures, or when unbreakable instruments are preferable. Glass bottles that are clear or colored can withstand higher temperatures and hold light-sensitive chemicals. Bottles are designed for specific operations, contents, or dispensing methods.

Percent (%) Solutions Calculator - PhysiologyWeb

Oct 05, 2013 · For example, adding 50 mL of ethanol to 50 mL of water will result in a total volume that is less than 100 mL. It is actually closer to 96 mL. Therefore, when preparing volume/volume percent solutions, it is always better to dissolve the solute in solvent and then add additional solvent to bring the total solution volume to the desired final value.

Ammonium acetate buffers - Crawford Scientific

For an ammonium acetate buffer in water, the eluent pH used for separation should be 3.8 to 5.8 when using formic acid as the pH modifier and 8.5 to 10.5 when ammonia is used to adjust the eluent pH. The caveat: once acetonitrile is added to the system this working range changes and the usable pH range becomes 5.2 to 7.2 or 7.9 to 9.9 at 60%
