Which item is used for drying and removing moisture from the specimen?

Drying specimens requires controlled heat to drive off moisture without damaging the material. A laboratory oven provides that—it's designed to maintain a set temperature and good airflow so moisture can be removed and the mass reaches a constant value. This makes it ideal for preparing samples for moisture-content determinations or any test where residual water could skew results. A beaker is just a container for liquids and won’t actively remove moisture. A universal testing machine is built to apply force and measure mechanical properties, not to dry samples. A vibrator helps settle powders or remove air pockets during preparation, but it doesn’t dry specimens.
