glass bottom petri dish
A glass bottom petri dish represents a significant advancement in laboratory equipment, combining traditional petri dish functionality with enhanced optical properties. These specialized vessels feature a thin glass bottom seamlessly fused to a polystyrene or glass upper chamber, creating an ideal environment for both cell culture and high-resolution microscopy. The glass bottom, typically measuring between 0.13-0.17mm in thickness, provides superior clarity and minimal autofluorescence compared to standard plastic dishes. This design enables researchers to conduct detailed cellular observations, live-cell imaging, and fluorescence microscopy without compromising sample integrity. The dishes come in various sizes, commonly ranging from 35mm to 100mm in diameter, with the glass bottom area precisely centered for optimal viewing. The construction ensures excellent chemical resistance, thermal stability, and compatibility with various imaging techniques, including confocal microscopy and phase-contrast imaging. These dishes maintain sterility through gamma irradiation or ethylene oxide treatment, making them suitable for long-term cell culture applications. The transparent bottom allows for direct visualization of cellular processes, protein interactions, and morphological changes in real-time, while the surrounding walls provide necessary containment and protection for the culture medium.
