- Methods Description
The pyknometer, together with its glass stopper, was placed into a thermostatically controlled oven at 20°C and - after thermal equilibrium - it was weighed using the analytical balance (W1). The pyknometer was filled with water which had been freshly boiled and cooled, and was placed again in the thermostatic oven at 20°C until thermal equilibrium.
The glass stopper was then fitted to the pyknometer and the exceeding water was removed by adsorbent paper, taking care not to withdraw water from the capillary.
After that, a new thermal equilibrium was reached in the thermostatic oven; the pyknometer was re-weighed (W2); the difference (W2 - W1) was the water equivalent (WE) of the pyknometer at 20°C.
The whole procedure was repeated using the test item saturated solution, obtaining W3 and W4 values; the difference (W3 - W4) was the liquid equivalent (LE) of the pyknometer at 20°C.
The pyknometer was empted, dried and placed again, with its glass stopper, in the thermostatic oven at 20°C until thermal equilibrium; then it was re-weighed (W5). About 5 g of test item were added to the pyknometer, so placed in the oven at 20°C until thermal equilibrium. Finally, it was re-weighed (W6).
A suitable amount of the test item saturated solution, necessary to completely fill the pyknometer was then added, taking care to wet the test item. The pyknometer was placed in the oven at 20°C until thermal equilibrium. Then the glass stopper was fitted to the pyknometer and the exceeding liquid was removed by adsorbent paper, taking care not to withdraw liquid from the capillary.
After a new thermal equilibrium had been reached in the thermostatic oven, the pyknometer was re-weighed (W7). - GLP compliance:

- Conclusions:
- From the experimental data obtained according to the guideline A.3 in Council Regulation (EC) No 440/2008 part A, CIPAC method MT 3.2 and OECD Test No 109, it can be concluded that the density of Delmopinolo HCl sample is 0.8860 g/mL at 20°C; the specific gravity is 0.8876 at 20°C, and the relative density (D204) is 0.8860.
- Executive summary:
The density of Delmopinolo HCl sample is 0.8860 g/mL at 20°C.
