Beakers and Flasks Beaker and flask
DWK Life sciences products are manufactured to the highest standards and offer a wide variety of beakers and flasks. The size range of beakers extends from... 5mL To 5L Not equal, conforms to ISO and DIN Standard, and supplemented with ISO 7056 other products. Although all flasks and beakers come with useful features, such as easy-to-read graduations and large labels, some are even more functional.
DURAN ® Beaker and flask
For decades, DURAN ® Beakers and flasks have long been reliable and trustworthy companions in laboratory work—and they remain so to this day. Depending on your application, choose from a wide variety of options. - Beakers—both low- and high-form—wide-neck and narrow-neck conical flasks, as well as round-bottom and flat-bottom flasks specially suited for heating applications—our... DURAN ® Super Duty The series features higher mechanical strength and allows for safer work in the laboratory, among other advantages. DURAN ® Beakers and Erlenmeyer flasks come with production batch numbers. / Trace the code. Use 8 A code consisting of several characters and the corresponding product number allow you to download certificates in bulk.
• For everyday laboratory applications, such as mixing, storage, and heating.
• Uniform wall thickness and enhanced thermal shock resistance.
• DURAN ® Super Duty The series features enhanced rims, resulting in higher mechanical strength.

When cultivating microorganisms in Erlenmeyer flasks on a shaker or orbital shaker, oxygen uptake typically becomes the limiting factor for cell growth. When used on a shaker... DURAN ® In a conical flask, this motion leads to the formation of a liquid sickle. The size of the sickle depends on the plate’s speed and the diameter of the vibration. The larger the surface area of the contents, the greater the gas-exchange area, and thus the greater the potential oxygen uptake. However, both the speed and the associated oxygen uptake can only be increased to a limited extent. New... DURAN ® The baffled flask has four baffles at the bottom, which disrupt laminar flow and generate turbulence, increasing both the liquid’s surface area and the gas-exchange area, thereby enhancing oxygen uptake. Laboratory experiments have shown that, compared to the standard... DURAN ® Compared to the conical flask, the dissolved oxygen level has doubled. DWK Life Sciences The conical flasks with baffles are manufactured entirely by automated machinery and allow for geometric replication. The wall thickness of the flasks has been increased to ensure excellent mechanical stability and guarantee a long service life for the products. • Made of borosilicate glass 3.3 Made into • The four baffles at the bottom are designed to create vortices, accelerating the vigorous flow of the liquid and enhancing the exchange between the liquid surface and oxygen—compared to the standard. DURAN ® Compared to the conical flask, the dissolved oxygen level has doubled. • At higher oscillation speeds, the baffle increases aeration, leading to better growth, especially for bacteria. • The molded bottom baffle can increase movement at lower speeds, enabling gentler media aeration for sensitive cultures. • Therefore, it can be used. DWK Life Sciences The time-tested membrane spiral-cap sealing flask, compared to other sealing mechanisms (such as those sealed with cotton wool), allows for repeatable gas exchange thanks to its spiral cap. • A special manufacturing process enables the production of complete threaded products in a two-stage process. • Offers three size ranges for process scale-up, with or without membrane spiral caps and pouring rings. • The increased wall thickness of the flask ensures excellent mechanical stability and a longer service life. • Features a screw cap and a pour spout ( PPI Material), its temperature limit: +140℃ • Single-batch delivery; batches can be downloaded from the official website.
