Smartphone Camera Stand for 90mm Petri Dishes

A custom-designed smartphone stand specifically created for taking consistent, high-quality photos of standard 90mm petri dishes. If you work in a lab, teach biology, or do microbiology at home, getting perfectly framed and consistent overhead shots of cultures can be a hassle. This support solves that by keeping your phone and the petri dish at a fixed, repeatable distance. The base features a fitted groove to center the dish perfectly every time, and the top plate provides a stable, flat surface for your smartphone with a viewing window for the camera lens. Perfect for: Tracking and documenting colony growth over time. Standardized image analysis (like colony counting). Creating time-lapses of microbial or fungal growth.
