The desiccator is used to store dried samples in a dry atmosphere. It should not be used to dry an object, but to maintain an already dried object indefinitely in a dry condition.
1. To open - slide lid horizontally across the top to one side until it comes off. Use one hand to hold the bottom of the desiccators while using the other hand to grasp the knob.
2. To close - place lid partly on the top and slide across until desiccators is completely closed and then rotate lid gently in both directions.
3. Do not attempt to lift lid off vertically.
4. Make sure the lid has enough grease around the ground glass rim - if necessary, spread Vaseline uniformly on the rim. When the lid is properly seated, the greased rim will appear.
5. If the desiccant appears wet or clumpy, it probably needs to be replaced with new dessicant. It is helpful to have a small amount of indicating desiccant present. When the color changes to pink, the desiccant should be replaced.
