DURAN® Baffled Flask, with GL 45 thread

DURAN® Baffled Flask, with GL 45 thread Oxygen intake is often the limiting factor for cell growth in the cultivation

DURAN® Erlenmeyer Flask, narrow neck

DURAN® Erlenmeyer Flask, narrow neck Thanks to their exceptional properties, such as excellent chemical resistance, nearly inert behaviour and high usage temperature, the original DURAN® Erlenmeyer flasks are ideal for use in laboratories. Moreover, the uniform wall thickness, minimal thermal expansion and the resultant high thermal shock resistance are outstanding characteristics. Therefore, DURAN® Erlenmeyer flasks are particularly suited to use with very high temperatures and fast temperature changes.

DURAN® Erlenmeyer Flask, wide neck

DURAN® Erlenmeyer Flask, wide neck Thanks to their exceptional properties, such as excellent chemical resistance, nearly inert behaviour and high

DURAN® Evaporating Flask, Pear shape,Socket 29/32

DURAN® Evaporating Flask, Pear shape,Socket 29/32 Evaporating flasks are a variant of round flasks and have a florentine pear shape.

DURAN® Flask, Kjeldahl

DURAN® Flask, Kjeldahl

DURAN® Kjeldahl flasks are subjected to extreme chemical and physical stresses. Therefore, the wall thickness should not be too thick to avoid overheating, which can lead to breakage due to remaining (permanent) stresses, on the one hand, and not too thin due to the noticeable glass removal in the alkaline medium, on the other hand. In order to offer the user the safest possible compromise while taking the technological conditions into account, the wall thickness of the DURAN® Kjeldahl flasks in the body are 1-2 mm.

DURAN® Flat Bottom Flask, narrow neck, with beaded rim

DURAN® Flat Bottom Flask, narrow neck, with beaded rim Abdominal vessels are called flasks in the laboratory and, in addition to beakers, are other universally applicable vessels. They are used e.g. for distillation or for heating liquids. Flasks are available in various designs: narrow and wide neck, with or without ground joint, as round or flat bottom flask. Depending on the application, the required flask with its specific components is selected.

DURAN® Round Bottom Flask, narrow neck, with beaded rim

DURAN® Round Bottom Flask, narrow neck, with beaded rim Abdominal vessels are called flasks in the laboratory and, in addition to beakers, are other universally applicable vessels. They are used e.g. for distillation or for heating liquids. Flasks are available in various designs: narrow and wide neck, with or without ground joint, as round or flat bottom flask. Depending on the application, the required flask with its specific components is selected.

DURAN® SUPER DUTY Erlenmeyer Flask, narrow neck

DURAN® SUPER DUTY Erlenmeyer Flask, narrow neck Life can be tough for laboratory glassware such as beakers, flasks and cylinders. Rough handling and laboratory processes like automated washing can cause damage and breakages. The DURAN® SUPER DUTY products were specially developed to better cope with laboratory life. The DURAN® SUPER DUTY products are characterized by a higher mechanical strength achieved by reinforcing the rim. As a result of this modification, the impact strength is improved, and the risk of accidental breakage is significantly reduced. The DURAN® SUPER DUTY products increase the safety in the laboratory and help to minimize the risk of injury. The longer life expectancy of the SUPER DUTY products means that they are more economical to use over the long term.
