Realistic 100 ml Class A volumetric flask in clear borosilicate glass (58 mm bulb, 165 mm high without stopper) with a ring calibration mark placed at the true 100 ml height of the modelled interior, NS 12/21 frosted joint and a blue octagonal polyethylene stopper. Includes an optional purple liquid object filled exactly to the mark.

Real-world scale (centimetre units), modelled from catalogue dimensions; origin at the base centre, resting on the ground plane.
Geometry: 11,928 polygons, 12,107 vertices (quads, with triangle fans only at the axis poles; no n-gons). Clean lathe topology with holding loops, one smoothing group, non-overlapping UVs.
Objects (grouped under one master group): Volumetric_Flask_100ml_Glass, Volumetric_Flask_100ml_Ground_Joint, Volumetric_Flask_100ml_Print_1, Volumetric_Flask_100ml_Print_2, Volumetric_Flask_100ml_Liquid, Volumetric_Flask_100ml_Stopper.
Materials: PBR Metal/Roughness with PNG texture sets (base color, metallic, roughness, normal; transmission for glass and liquid; opacity cutout for the enamel print). Clear borosilicate glass (IOR 1.47), frosted ground-glass joint, polyethylene stopper, liquid (IOR 1.333).
Formats: Blender 4.2 LTS (.blend, Cycles, StemCell-spec scene: cm units, master group, PBR textures); FBX; OBJ/MTL; glTF binary (.glb); USDZ.
