Original DURAN® Erlenmeyer flasks are ideal for use in laboratories.

Higher impact strength, mechanical strength and stability achieved by reinforced rim.

Erlenmeyer shape, vacuum resistant due to the heavy wall thickness.

Higher impact strength, mechanical strength and stability achieved by reinforced rim.

Slit sieve support serves as a carrier for membrane and paper filters.

Without certificate of conformity, scratched graduation mark and octagonal stopper from PE. White print with batch certificate.

Tight closure due to standard ground joint.

Heavy-wall (filtering beaker) with easy-to-read scale with graduation marks.

Round bottom, very resistant to mechanical loading.

Vacuum resistant filtering flask due to the heavy wall thickness, bottle shape.

Wide neck enables easy filling and cleaning.

Higher impact strength, mechanical strength and stability achieved by reinforced rim.

Four baffled-bottom flasks cause a turbulent flow, increase the gas exchange surface and produce a higher oxygen transfer.

Suitable for liquid-solid filtration using a filter paper.

Large stem diameter makes it suitable for transferring solids.

Calibration is based on the poured in volume (“In”) at a +20°C reference temperature.
