The movement causes a liquid sickle to form when using DURAN® Erlenmeyer flasks on a vibrator. The size of the sickle depends on the speed of the board and the vibration diameter. The greater the surface area of the contents, the greater the gas exchange area and therefore the potential oxygen intake. The speed and the associated oxygen intake can, however, only be increased to a limited extent. The new DURAN® baffled flask with four baffles on the bottom disrupts the laminar flow and produces a turbulent flow. The surface area of the liquid and the gas exchange area are increased, thereby increasing the oxygen intake. Laboratory trials have demonstrated that the oxygen intake is doubled by the baffles compared to a standard DURAN® Erlenmeyer flask. The Erlenmeyer flasks with baffles from the DWK Life Sciences can be geometrically reproduced due to completely automated and mechanical production. The wall thickness of the flasks was increased to achieve an excellent mechanical stability and to guarantee a long service life of the products. The special production process enables the manufacture of the product complete with thread in a two-stage process. The flasks can therefore be sealed with the tried-and-tested membrane screw cap from the DWK Life Sciences. This enables a reproducible gas exchange compared to other sealing mechanisms e.g. sealing with cotton wool.\u003cdiv class=\"wdi-tab-wrapper\"\u003e\n  \u003cul class=\"tabs\"\u003e\n    \u003cli style=\"width: 50% !important;\"\u003e\u003ca class=\"active\" href=\"#tab1\"\u003eSpecifications\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli style=\"width: 50% !important;\"\u003e\u003ca href=\"#tab2\"\u003eDownloads\u003c\/a\u003e\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cul class=\"tabs-content\"\u003e\n    \u003cli class=\"active\" id=\"tab1\"\u003e\n      \u003cdiv class=\"wdi-grid-wrapper\"\u003e \n        \u003c!--+++++++++++ BEGIN VARIABLE CONTENT +++++++++++--\u003e\n        \u003cdiv class=\"wdi-grid-col\"\u003e \n          \n          \u003c!------------------------- LEFT CONTENT DIVIDER -----------------------------\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Height (mm)\u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e 221 \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Diameter (mm) \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e 135 \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Capacity (mL) \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e 1000 \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Thread \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e  \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Material \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e \nBoro 3.3 \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Sterile \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e No \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n          \u003cdiv class=\"wdi-inner-wrapper\"\u003e\n            \u003cdiv style=\"text-align: left !important;\" class=\"wdi-inner-col wdi-inner-col-left wdi-strong\"\u003e\n              \u003cp style=\"text-align: left !important;\"\u003e Quantity \u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"wdi-inner-col wdi-inner-col-right\"\u003e\n              \u003cp\u003e 1      \u003c\/p\u003e\n            \u003c\/div\u003e\n          \u003c\/div\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/li\u003e\n    \u003cli id=\"tab2\"\u003e\n      \u003cdiv class=\"b\" style=\"float: left;
