Description

Dessicator With Knob I.D. 6″

This dessicator is a workhorse in any laboratory, providing a controlled environment for drying and storing moisture-sensitive materials. Here’s a detailed breakdown of its features:

Construction:

• Chamber: Crafted from robust, clear borosilicate glass (often referred to as Pyrex) for exceptional durability and unobstructed visibility of your samples within. A typical 6″ ID dessicator boasts a diameter of around 15 centimeters (approximately 6 inches).
• Lid: Features a ground-glass design that forms an airtight seal with the chamber. It typically has a knob or handle for convenient 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 (if stopcock included): The stopcock (if present) allows for controlled introduction or evacuation of air, enabling adjustment of the pressure within the chamber.
