A dramatic dark studio product photograph of premium research-grade lyophilized powder vials. Several amber and clear glass vials with crimp seals containing white lyophilized powder, arranged on a glossy pitch-black surface. Deep plum-purple gradient rim lighting glows from behind and the sides, casting rich violet reflections on the black surface. Volumetric purple haze in the background. Ultra-premium, clinical, luxury pharmaceutical aesthetic. Cinematic, high-contrast, moody. No text, no labels readable. Photographic realism.
