DURAN beaker, tall design with spout (50 ml – 3000 ml)

Product information "DURAN beaker, tall, with graduations and spout (50 ml – 3000 ml)"

DURAN beakers in the tall design with a spout represent a masterfully balanced, materials-science-optimised and flexibly scalable system solution for the precise mixing, sample preparation, heating and controlled transfer of liquid media in modern day-to-day laboratory work. Available in a finely graded range of volumes from 50 ml for small-scale analytical batches up to 3000 ml (3 litres) for larger process volumes, this series of glassware forms the functional backbone of chemical, biological, pharmaceutical and clinical research and quality control laboratories. For thermally intensive processes or the precise dosing of aggressive liquids, this system guarantees gentle handling of materials, contamination-free operation and process reliability.

Thermomechanical stability and borosilicate glass 3.3

The material science 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 completely uniformly during heating on laboratory hotplates or using gas burners, without any thermal stress peaks that could damage the material. This effectively minimises the risk of heat-induced material fractures during demanding daily continuous use.

Chemical inertness and a narrow, tall geometry with a 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. The tall, narrower design, from which the product takes its name, offers tangible procedural advantages over the low-profile version: the reduced liquid surface area noticeably minimises evaporation losses during boiling, whilst the raised side walls provide excellent splash protection during mechanical stirring or titrations. The geometrically precise spout also ensures clean, drip-free and controlled pouring of media, which significantly enhances safety when handling toxic substances.

Compliance with standards, complete 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. All variants feature permanently etched, high-contrast white graduations (markings) for rapid volume estimation, as well as a generous labelling area for reliable identification of the sample batch. In addition, each beaker has a Retrace Code, which enables 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 for daily requirements to the practical small pack for large vessels.

Individual requirements & accessories

To ensure the DURAN beakers integrate seamlessly into your daily laboratory routine, we stock a wide range of suitable accessories. For mechanical mixing processes, we offer high-quality, PTFE-coated magnetic stirring bars in lengths precisely matched to the respective base diameters. To protect against evaporation losses, splashes or contamination from the ambient air, the tall beakers can be perfectly covered with laboratory watch glasses or sealed with flexible Parafilm-M laboratory films. For gentle temperature control in water, sand or oil baths, our range also includes heat-resistant stand clamps, sleeves and stainless steel vessel holders. Make use of our technical procurement service to tailor your analytical infrastructure to your specific requirements.
