pH buffers come in different forms... from prepared liquid to powder pillows. This video shows some of these examples, as well as standard preparation for powdered standards
The proper way to use volumetric flasks, since they are marked TC "to contain" is to add the power, then make up to the mark, then transfer to another container such as the small beakers. Of course pH buffers shouldn't require that much accuracy.
