有d藥丸藥水用茶茶地啡啡地ge樽裝住,其實有乜特別作用?

因為呢啲都係化學物質，而且某些藥物，藥水的狀態會比較不穩定，如果加上光的照射，會令温度上升，以致產生化學反應，容易變質。

The brownish colour may be to filter out certain light wave.

Some solutions are cannot let the sun shine directly, or they will explode, leak...These usually use on the danger things. These brown colored bottles can block the sunlight, if the solution is not danger (Example: Water) will use the clear bottle (Normal bottle). You can ask the Chemisty teacher for more imformation about these brown colored bottles.

其實係咪為左唔比陽光照射得太厲害呢?應該有大的可能
有時有d藥水等會蒸發
