Division B.3 Apparatus and equipment

Usual laboratory apparatus and in particular the following:

1. B.3.1.

   Digital display densimeter

   Electronic densimeter for performing such measurements must be capable of expressing density in g/ml to 5 decimal places.

   Note 1:

   The densimeter should be placed on a perfectly stable stand that is insulated from all vibrations.

2. B.3.2.

   Temperature regulation

   The densimeter's performance is valid only if the measuring cell is connected to a built-in temperature regulator that can achieve the same temperature stability of ± 0,02 °C or better.

   Note 2:

   The precise setting and monitoring of the temperature in the measuring cell are very important, for an error of 0,1 °C can lead to a variation in density of the order of 0,1 kg/m³.

3. B.3.3.

   Sample injection syringes or auto sampler.
