DURAN® Dropping / Dropper Bottle, Clear, Amber, Soda-Lime Glass
DURAN® Dropping / Dropper Bottle, Clear, Amber, Soda-Lime Glass
Dropping bottles are suitable for liquids which need to be dispensed in small amounts, especially drop by drop. Amber soda lime glass bottle provides protection for photosensitive reagents from light. Supplied with rubber teat and clear ground jointed dropping pipette. Replacement clear glass pipettes and natural rubber teats are available.

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® 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
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.
