Description

Dessicator With Knob I.D. 12″

This dessicator is a behemoth in the laboratory world, offering unparalleled capacity for handling and protecting your moisture-sensitive materials. Here’s a comprehensive breakdown of its features and functionalities:

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 12″ ID dessicator boasts a massive diameter of around 30.5 centimeters (approximately 12 inches). This expansive chamber allows you to accommodate significantly larger samples or larger quantities of materials compared to smaller desiccators.
  • 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 due to the sheer size of the dessicator.
  • 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 Massive Samples: This dessicator is ideal for drying exceptionally large biological specimens, chemicals, or electronic components.
  • Bulk Storage for Moisture-Sensitive Materials: Effectively preserves hygroscopic (water-absorbing) materials like pharmaceuticals, electronic components, or dehydrated food in significant quantities by preventing them from picking up moisture.
  • Desiccating Large-Scale Experiments: Certain large-scale chemical reactions require a dry environment, and this dessicator can provide the necessary conditions for successful experimentation on a grander scale.

Benefits:

  • Unmatched Capacity: The enormous 12″ diameter chamber allows you to handle projects involving very large samples or substantial quantities of materials.
  • 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, even with demanding applications.
  • Clear Visibility: The transparent glass chamber allows for easy monitoring of samples inside the desiccator, despite its size.
  • 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.

Specifications (typical for a 12″ ID Dessicator with Knob):

  • Diameter: 30.5 cm (approximately 12 inches)
  • Material: Borosilicate glass chamber
  • Lid: Ground glass with knob
  • Porcelain Plate: Included, size may vary
