Glass Desiccator, 180-300 mm Inner Diameter

Excellent airtightness, though the larger one is quite heavy to move around.

The glass is thick and feels very sturdy. Perfect for long-term lab use.

Works perfectly fine, but you have to be careful not to chip the rim.

Very impressed by the glass quality and the smooth porcelain plate inside.

My samples stay completely dry for weeks. Works just as expected.
