DURAN beaker, tall, with graduations, without spout (50 ml – 1000 ml) – 250 ml

Product information "DURAN beaker, tall, with graduations, without spout (50 ml – 1000 ml) – 250 ml"

DURAN beakers in the tall design without a spout represent a fundamental, materials-science-optimised and flexibly scalable system solution for the precise preparation, mixing, heating and storage of liquid media and reagents in everyday laboratory work. Available in a closely graded range of volumes from 50 ml to 1000 ml, this series of glassware forms the functional foundation of chemical, biological, clinical and industrial laboratories. For complex syntheses, gravimetric sample preparation or thermal processes, the structural reliability of the vessel is the primary criterion for working in a way that is gentle on materials, contamination-free and process-safe.

Thermomechanical stability and borosilicate glass 3.3

The materials science basis of the laboratory beakers is original DURAN borosilicate glass 3.3, a material of the very highest calibre. This special glass has an extremely low coefficient of linear expansion, ensuring outstanding thermal stability and excellent resistance to thermal shock. A uniform wall thickness distribution across the entire cylinder and the flat base of the vessel ensures that thermal energy is transferred completely evenly when heating on laboratory hotplates or using gas burners. This effectively minimises the risk of thermally induced stress cracks in the material during continuous daily use.

Chemical inertness and functional design without a spout

From a chemical perspective, DURAN beakers offer virtually universal resistance to highly corrosive acids, alkalis, halogens and organic solvents. The non-porous, smooth quartz glass surface prevents irreversible adsorption of sample components and allows for residue-free cleaning and sterilisation that is gentle on the material. The special geometry of the tall, spoutless design is ideal for stirring operations using mechanical laboratory stirrers or magnetic stirring bars, as the straight sidewall minimises the risk of uncontrolled splashing of the liquid. Permanently etched white graduations with marked intervals allow for quick and error-free reading of the volume, whilst a generous labelling area facilitates the reliable identification of the sample batch.

Structural integrity and rigorous GLP compliance

The structural quality of the beaker is ensured through strict compliance with international standards such as DIN 12331 and ISO 3819. In addition, every DURAN beaker features a printed Retrace Code. This enables laboratory staff to easily access a batch-specific quality and conformity certificate directly via the internet. For laboratory managers and those responsible for quality management, this seamless traceability is an essential criterion for maintaining strict audit requirements in accordance with rigorous GLP and GMP guidelines.

Customised 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 stir bars in lengths precisely matched to the diameters (50 ml to 1000 ml). To protect against evaporation losses or contamination from the ambient air, the beakers can be perfectly covered with laboratory watch glasses or flexible Parafilm-M laboratory films. For gentle temperature control in water or oil baths, our range also includes heat-resistant stand clamps, sleeves and stainless steel vessel holders. Please make use of our technical procurement service to design your analytical infrastructure to suit your specific requirements.
