Vacuum desiccator:

Thanks for letting me know about Fisher Scientific’s range of Vacuum desiccator It’s always helpful to be aware of different suppliers and options for scientific equipment.

Here’s a guide on how to use a vacuum desiccator:

1. Preparation Vacuum desiccator:

• Inspect for Damage: Examine the desiccator for any cracks, chips, or compromised seals. Never use a damaged desiccator.
• Add Desiccants: Place a drying agent, typically silica gel, into the bottom of the desiccator. Ensure it doesn’t surpass the level of the plate.
• Apply Lubricant: Apply a thin layer of vacuum grease (not silicone grease) to the ground surfaces of the lid and base to create an airtight seal.

2. Placing Samples Vacuum desiccator:

• Position Samples: Place your samples on a suitable surface, like a watch glass or weighing paper, and position them on the desiccator plate.

 Creating a Vacuum:

• Connect Vacuum Pump: Attach a vacuum pump to the side tube of the desiccator using a flexible vacuum hose.
• Open Stopcock: Rotate the stopcock to open it, allowing air to be drawn out by the vacuum pump.
• Monitor Vacuum: Keep an eye on the vacuum gauge (if available) to ensure sufficient vacuum is achieved.
• Close Stopcock: Once the desired vacuum level is reached, close the stopcock to maintain the vacuum.

Allowing Drying:

• Leave Samples: Leave the samples in the vacuum desiccator for the required drying time. This can vary depending on the nature of the samples and the drying agent used.

Releasing Vacuum:

• Open Stopcock Gradually: To release the vacuum, slowly and partially open the stopcock to allow air to enter gradually. This prevents sudden pressure changes that could damage samples or the desiccator.
• Equalize Pressure: Once the pressure inside the desiccator equalizes with the outside air, the lid can be safely removed.

Opening Desiccator:

• Slide Lid: Gently slide the lid off the desiccator, taking care not to disrupt the samples or the drying agent.

 Removing Samples:

• Retrieve Samples: Carefully remove your dried samples from the desiccator.

Additional Tips:

• Handle with Care: Avoid placing heavy objects on the desiccator lid or dropping the desiccator.
• Regenerate Desiccants: Reactivate used silica gel by heating it in an oven to remove absorbed moisture.
• Store Properly: Keep the desiccator tightly closed when not in use to maintain the effectiveness of the drying agent.
