DURAN beakers, short-necked, with spout (5 ml – 10,000 ml)
DURAN beakers in the low-profile design with a spout represent the most versatile, materials-science-optimised and flexibly scalable system solution for preparing, mixing, briefly heating and precisely transferring liquid media, suspensions and reagents in everyday laboratory work. Available in an extremely wide range of volumes, from delicate 5 ml beakers for microanalysis right up to high-volume 10,000 ml (10 litre) beakers for pilot plant use, this range of glassware forms the indispensable backbone of chemical, biological, pharmaceutical and clinical laboratories. Whether for thermal processes, physical stirring operations or simple logistical sample preparation, this range guarantees gentle handling of materials, contamination-free working and process reliability. Thermomechanical stability and borosilicate glass 3.3 The material-related foundation of this series of laboratory beakers is based on genuine DURAN borosilicate glass 3.3, a premium glass material of the very highest calibre. This special glass has an extremely low coefficient of linear expansion, ensuring the user outstanding thermal stability as well as excellent resistance to thermal shock. A strictly monitored, completely homogeneous wall thickness distribution across the entire cylinder and the flat base of the vessel ensures that thermal energy is transferred evenly and without thermal stress peaks when heating on laboratory hotplates or using gas burners. This effectively minimises the risk of heat-induced material fractures during demanding daily continuous use. Chemical inertness and flow-optimised spout From a chemical perspective, DURAN beakers offer virtually universal resistance to highly corrosive acids, alkalis, halogens and organic compounds. The non-porous, smooth quartz glass surface prevents irreversible adsorption of sample components and allows for residue-free, gentle cleaning and sterilisation. A defining mechanical feature is the geometrically precise spout. This flow-optimised lip ensures clean, drip-free and controlled pouring of liquids, which significantly enhances safety when handling toxic or corrosive substances. Compliance with standards, full traceability and quantities tailored to requirements The manufacturing quality of the beakers is permanently ensured through strict compliance with international standards such as DIN 12331 and ISO 3819. Depending on the selected nominal volume, the beakers feature a permanently etched, high-contrast white graduation (markings) for rapid volume estimation, as well as a generous labelling area for reliable process-safe marking (Note: Very small volumes, such as the 5 ml and 10 ml variants, are supplied without graduations due to their limited geometry). In addition, each beaker features a Retrace Code, which enables the direct online retrieval of a batch-specific quality certificate (GLP/GMP-compliant). To perfectly meet the logistical requirements of day-to-day laboratory and procurement operations, the quantities supplied per sales unit (SU) are strictly graded according to specific applications – ranging from the cost-effective laboratory box to the individually packaged, transport-safe large container.
