PLATES FOR DESSICATORS

Desiccator Plates

In your laboratory environment, the efficiency of a desiccator depends not only on an airtight seal and the desiccant agent but also on how samples are arranged and exposed to the controlled atmosphere. This is where desiccator plates play a fundamental role, acting as the key support that ensures maximum effectiveness in the drying or vacuum storage process. They are not mere accessories—they are critical components that ensure proper air circulation or uniform vacuum evacuation around your samples.

A desiccator plate is a perforated disc inserted inside the container, usually resting on a ledge or designated support. Its primary purpose is to elevate your samples above the desiccant agent (such as silica gel) placed at the bottom of the desiccator. This elevation prevents direct contact between the samples and the desiccant, avoiding potential contamination and facilitating handling. Beyond that, the perforations in the plate are essential—they allow the dry environment to circulate evenly throughout the entire volume of the desiccator, effectively reaching every sample.

Choosing the right plate is just as important as selecting the desiccator itself. A well-designed plate made of the proper material ensures efficient drying and preserves your materials under optimal conditions.

The Vital Role of Air Distribution

The effectiveness of any drying process relies on the desiccant’s ability to absorb moisture from the surrounding atmosphere. However, if your samples are not adequately exposed to this dry atmosphere, the process becomes slow and inefficient. Desiccator plates solve this challenge by ensuring uniform distribution of the controlled atmosphere.

The perforations in the plate serve as channels that allow the pre-dried air (or vacuum) to circulate freely both below and above your samples. This prevents "pockets" of moisture or stagnant air from forming around the materials, maximizing exposure and accelerating the drying process. In vacuum desiccators, a proper plate is indispensable for efficient air evacuation and uniform vacuum establishment across the entire volume.

In addition to facilitating circulation, the plate offers a flat and stable surface for placing containers such as Petri dishes, beakers, etc. This stability is crucial for avoiding movement or tipping of your samples, especially when working under vacuum or while handling the desiccator.

Types of Desiccator Plates and Their Features

Desiccator plates are available in various materials, each with specific properties suited for different applications and laboratory conditions. At Pobel, we understand the importance of compatibility and durability.

Here are the features of two main types of plates available in our catalog, designed to complement your glass or plastic desiccators:

• Porcelain Plates: The classic and most versatile choice, especially for glass desiccators. Their high temperature resistance makes them ideal for placing hot samples directly from an oven or hotplate, allowing safe cooling in a dry environment. Their chemical durability makes them compatible with a wide range of substances.

• Polypropylene (PP) Plates: An excellent alternative, particularly for plastic desiccators or where lightness and impact resistance are priorities. These plates are highly resistant to various chemicals and extremely durable. Though unsuitable for high temperatures, their low weight and ease of cleaning make them very practical for general lab use.

Integration and Compatibility with Your Lab Equipment

When selecting desiccator plates, it’s essential to consider compatibility with the type of desiccator you use—whether plastic or glass. Plates come in different diameters to fit standard desiccator sizes. Ensuring a perfect fit into the internal ledge of your desiccator is vital to provide a stable base for your samples and optimal airflow.

For vacuum desiccators, the plate is even more critical. It facilitates uniform air evacuation, allowing the vacuum to be quickly and efficiently established across the entire chamber. Without a suitable perforated plate, vacuum creation may be uneven or ineffective, compromising drying or preservation.

Also, consider the type of desiccant you use. Plates not only separate your samples from the desiccant but also allow easy access for replacement or regeneration—an essential step to maintain peak desiccator efficiency.
