The plastic desiccators are the most durable designs when drying or storing sensitive materials. The clear, shatterproof enclosures create a stable environment to prevent premature reactions and ensure accurate results. Built in manual pumps or fitted vacuums accelerate the drying process. Models will not implode even at full vacuum level. Easy release buttons gradually allows air into the container. Plastic desiccators come in different sizes and may include hygrometers for atmospheric monitoring.
