Dessicator With Knob I.D. 7″
This dessicator is a laboratory workhorse designed to create and maintain a dry environment for your samples and experiments. Here’s a comprehensive breakdown of its features:
Construction:
- Chamber: Made of sturdy, clear borosilicate glass (often called Pyrex) for exceptional durability and excellent visibility of your samples inside. A typical 7″ ID dessicator boasts a diameter of around 17.8 centimeters (approximately 7 inches).
- Lid: Features a ground-glass design that forms an airtight seal with the chamber. It usually has a knob or handle for easy lifting and manipulation.
- Stopcock (Optional): Some models may include a glass valve with a PTFE (Teflon) plug. This allows for controlled introduction or evacuation of air, often connecting to a hose for attaching a vacuum pump (sold separately).
- Porcelain Plate: A perforated plate sits inside the chamber, elevating samples and enabling air circulation.
Functionality:
- Desiccation: Primarily functions by creating a dry environment for your samples. You can achieve this in two ways:
- Passive Desiccation: Place desiccants like silica gel or molecular sieves (sold separately) inside the chamber. These materials absorb moisture from the air, effectively drying the environment.
- Vacuum Desiccation (if stopcock included): Connect the dessicator to a vacuum pump (not included) to remove air and moisture actively. This creates a low-pressure environment ideal for faster drying or applications requiring an extremely dry atmosphere.
Applications:
- Drying Samples: This dessicator is perfect for gently drying biological specimens, chemicals, or electronic components.
- Storing Moisture-Sensitive Materials: Effectively preserves hygroscopic (water-absorbing) materials like pharmaceuticals, electronic components, or dehydrated food by preventing them from picking up moisture.
- Desiccating Reactions: Certain chemical reactions require a dry environment, and this dessicator can provide the necessary conditions for successful experimentation.
Benefits:
- Efficient Moisture Removal: Provides various methods for achieving a low-moisture environment to suit your needs (desiccants or vacuum pump).
- Durable Construction: Built with chemical-resistant borosilicate glass for long-lasting use in the lab.
- Clear Visibility: The transparent glass chamber allows for easy monitoring of samples inside the desiccator.
- Airtight Seal: The ground-glass lid ensures a moisture-proof environment, protecting your samples from external humidity.
- Controlled Atmosphere (Optional): The stopcock (if present) allows for controlled introduction or evacuation of air, enabling adjustment of the pressure within the chamber.
