实验室玻璃器皿3D线框模型

白色纯背景，灰黑色3D线框工程渲染，浅灰半透明填充，实验室玻璃器皿与支架横向铺开。左侧横向试管架插有多根试管，前排多个深灰玻璃试剂瓶带滴管盖，旁边有玻璃滴管；中央为铁架台，带长立杆、十字夹、悬垂试管、带刻度大烧杯和方形底座；右侧为高量筒、弯曲玻璃管、试管架、小试剂瓶、锥形瓶和漏斗状玻璃件；前景散落滴管与搅拌棒。物品高低错落，略俯视视角，均匀冷灰光照，弱阴影，16:9横版，单色工程制图效果，无人物，无文字。

3D wireframe engineering render on a pure white background, monochrome gray-black linework with pale gray translucent fills, a dense horizontal arrangement of laboratory glassware and stands. On the left, a horizontal test-tube rack holding multiple test tubes, several dark gray glass reagent bottles with dropper caps in the foreground, and a glass dropper; in the center, a retort stand with a tall vertical rod, cross clamp, suspended test tube, graduated beaker, and square base; on the right, a tall graduated cylinder with a bent glass tube, test-tube racks, small reagent bottles, a conical flask, and a funnel-shaped glass piece; scattered droppers and stirring rods in the foreground. High-low arrangement, wide horizontal composition, slight top-down view, even cool gray lighting, soft shadows, 16:9 aspect ratio, monochrome engineering-drawing effect, no people, no text.
