VWR 467 Series – Excellence in porcelain desiccant plates for controlled, uniform and safe drying
In scientific environments where humidity is a critical factor, VWR's 467 series porcelain desiccant plates are a professional solution for controlling the internal atmosphere of desiccators. Compliant with DIN 12911, these plates have been specifically designed to ensure maximum efficiency in drying, cooling or preserving sensitive samples.
Made from high-quality laboratory porcelain, they offer outstanding resistance to corrosive chemicals, high temperatures and sudden temperature changes. This robustness makes them durable, even when subjected to intensive cleaning cycles or prolonged daily use. The dense, vitrified material prevents the absorption of moisture or contaminants, ensuring clean and reliable analyses.
Their ingenious design includes a 20 mm central hole for inserting measuring devices or specific equipment, as well as a series of small 5 mm filtration holes evenly distributed across the entire surface. This configuration promotes even circulation of dry air within the desiccator chamber, preventing pockets of residual moisture that could compromise the quality or stability of stored samples. The efficient air flow ensures consistent drying across the entire surface, even for the most demanding applications.
Models 467-0100, 467-0101, 467-0102, 467-0103 and 467-0104 cover diameters ranging from 140 mm to 280 mm, making these plates compatible with a wide range of desiccators commonly used in laboratories. This diversity allows for great flexibility in drying procedures, regardless of sample format or device capacity. They integrate perfectly into borosilicate glass or polycarbonate drying systems, whether vacuum or ambient pressure.
In addition to their technical function, these plates embody the rigour of scientific industrial design: their smooth, non-porous surface limits residue adhesion and facilitates cleaning. They are also autoclavable, making them suitable for sterilisation protocols. Their use helps to create a clean, controlled environment that complies with the quality standards in force in certified laboratories.
Their mechanical stability also ensures safe handling, even under the most demanding laboratory conditions. Unlike some metal or plastic alternatives, porcelain does not deform with heat, does not react chemically with stored substances and does not release any particles or components that could interfere with analyses.
Whether in analytical chemistry, molecular biology, quality control, environmental science or pharmaceutical research, laboratories need rigorous humidity control. With VWR 467 plates, professionals can work reliably, consistently and safely. They represent a long-term and essential investment in dry environment management and maintaining optimal experimental conditions.
