How to Carefully Handle a Laboratory Desiccator

WaFer Storage Desiccator Cabinets 1

A laboratory desiccator is a thick glass jar that is closed on all sides and is in the shape of a circle. It’s a common piece of lab equipment because of all the cool things you can do with it, like. Materials used for weighing to a standard are called “standards,” and they need a dry storage environment to maintain their integrity.

Prolonged exposure to humidity when storing hygroscopic materials

The drying process causes certain products, such pharmaceuticals, to lose some of their original volume, and this may be measured.

The drying ingredient, desiccant, is contained on a perforated plate that rests on the bottom of the desiccator. Anhydrous calcium chloride, drierite (calcium sulphate), and silica are just a few of the drying agents often utilized in manufacturing.

This kind of desiccant may be regenerated by heating. Common practice calls for the addition of a small amount of a cobalt indicator chemical, whose color shifts from blue to pink when exposed to water. This will let you know when to replace the desiccant. The Global Lab Supply offers the best products.

The Laboratory Desiccator effectiveness depends on its ability to be sealed off so that its contents never come into contact with ambient air. Many dehydrators include vacuum connections that enable the internal air to be evacuated, making them ideal for long-term storage of materials that would deteriorate if exposed to moisture.

Multiple Desiccant Options

Desiccators may be broken down into four categories:


That serves as desiccant cartridges and, depending on use, need to be changed periodically. The traditional laboratory desiccator is very economical, although requiring close monitoring.


The vacuum desiccator can’t function without a pump to evacuate any remaining air or moisture from the container. The time needed to complete the suction operation varies from model to model.


This desiccator is equipped with electrical fans and heaters that are always running to keep the inside at a constant, dry temperature. It requires nothing in the way of upkeep and is quite reliable. However, the cost might be prohibitive for others.

Emission of Gas

The drying agent employed in the desiccator is a combination of nitrogen and argon. To keep the desiccator’s surroundings dry, they work more quickly than other approaches.

This is how a desiccant works:

There are two main types of applications for a desiccator, which is an airtight container. The first method involves releasing the moisture that has built up within the desiccator by evaporation. This is done to avoid damage to electronic components and chemical samples that are especially vulnerable to humidity. The second method entails protecting any potential biological or carbon dating elements while keeping the chamber at an adequate humidity level.

Desiccant alternatives include silica gel cartridges, which may be used in a desiccator. This is only one example of [what I mean] as a child, you could have unwrapped a brand new pair of shoes to find dozens of small bead packets strewn around the inside. These are called silica gel packages, and they function similarly to silica gel cartridges but are smaller. These cartridges are ideal for use when storing samples since they prevent condensation from forming in the storage area. Laboratory Desiccator by Global Lab Supply you can expect specific products.

Positive Effects of Desiccant Use

Our laboratory equipment is designed to absorb moisture in wet environments, so your valuables will remain clean and dry. Further, they stop any hygroscopic compounds from interacting with the moisture that is created in humid environments.

Desiccator as Usual

This apparatus needs constant human intervention and supervision. It will absorb all the moisture and then you’ll have to either replace it or reactivate the desiccant by heating it. These condominiums are convenient, affordable, and provide a variety of amenities.

Overusing a vacuum might cause it to explode, so it’s crucial to stick to the manufacturer’s instructions. Deliberately release the suction by turning the stop-cock on top of the container. If you want to open the lid, try sliding it. If the lid is stuck and won’t slide, you may use a small spatula to carefully pry it away from the container’s body, allowing the lid to slide more easily. A hissing noise indicates that the suction has been released. You need to slide the top cover while firmly gripping the bottom.

A desiccator is an invaluable tool for the constant storage of moisture-sensitive compounds, the maintenance of standards, and the execution of tasks that require weighing to an accurate weight. However, it is not recommended to store compounds that are highly reactive with water, such as sodium metal, since the process of opening the container can cause a violent reaction if the container comes into touch with wet air.
