3D渲染实验室科研场景试管滴管商业照片

A scientific dropper (pipette) made of soft clay with a translucent blue gradient bulb and a clear gradient stem, resting against a small, low-form clay beaker (clear with measurement marks). Tilted for a lab aesthetic. A tiny, bubbling liquid droplet or a molecule icon serves as the chat bubble. Warm, curious and experimental lighting on white.
