Beschreibung
Round-bottom flask 500 ml KS 35/20 coated is a single-neck laboratory flask fitted with a spherical ground joint KS 35/20 for distillation, reaction and receiving applications. Fabricated from clear borosilicate glass 3.3, it delivers strong chemical resistance and thermal performance suitable for demanding laboratory environments. The vessel offers a nominal volume of 0,5 l, an outer diameter of 105 mm and a height of 170 mm. Its plastic coating improves impact resistance and provides an extra safety barrier by helping to contain liquids if the glass is damaged. The spherical joint enables secure coupling within standard ground-joint apparatus, while the transparent body allows continuous visual monitoring of contents. Available in packs of 10 pieces from manufacturer Witeg, this coated round-bottom flask is well matched to preparative work, teaching labs and routine synthesis where both mechanical protection and optical clarity are required. The single-neck layout keeps handling straightforward across common laboratory glassware setups.
