Product Description

Marienfeld 4110308 300ml Wide Neck Borosilicate 3.3 Erlenmeyer Conical Flask

Model 4110308 is a professional wide-mouth Erlenmeyer flask manufactured in Germany by Paul Marienfeld Superior, compliant with DIN 12385 standard, specially developed for daily mixing, titration, microbial culture and liquid preparation in analytical labs, pharmaceutical QC and academic research institutions.
Constructed from top-grade borosilicate 3.3 glass, this 300ml conical flask features minimal thermal expansion and superior chemical inertness, supporting repeated high-temperature autoclave sterilization without deformation or cracking. The 50mm extra-wide neck solves the operation bottleneck of narrow-mouth flasks: solid culture media powders, high-viscosity reagents and large-volume sampling can be completed smoothly without blockage or splashing.
The reinforced beaded rim enhances durability against daily collision and pouring abrasion. Permanent white approximate graduation lines provide rapid volume estimation, paired with a blank marking panel for sample batch coding. Its unique sloped cone and wide flat base enable stable swirling during titration, uniform aeration in shaking incubator cell culture, and safe heating on laboratory hot plates.
Packed 10 pieces per carton, this Marienfeld wide neck Erlenmeyer flask is widely recognized for consistent glass quality across global chemistry labs, biotech cell culture platforms, cosmetic testing centers and university teaching classrooms. It is a universal all-purpose lab glassware for liquid mixing, microbial broth cultivation, titration reaction and temporary reagent storage.
Note: Graduations are for approximate reference only, not for high-precision volumetric calibration.
