35mm Glass Bottom Dish for Laser Confocal Imaging – D15mm
The 35mm glass bottom culture dish features a thickened bottom and minimized width difference between the upper cover and lower bottom to improve handling stability. The circular inlaid design with a thickness of 0.19-0.22 mm provides a clean, generous viewing area for imaging. It uses healthcare-grade shadowless glue to bond paired cells securely while remaining non-toxic for safe confocal microscope observation. Best for researchers performing laser confocal imaging who need reliable stability and clear imaging surfaces. Considerations: ensure compatibility with your imaging system and avoid excessive handling that may stress the bond area.
FTjireyr 35mm Glass Bottom Dish with D20mm Slide – 15/20mm
This FTjireyr dish uses a thickened glass bottom and a reduced width difference to prevent unintentional opening and enhance stability during handling. Made from high transparency polystyrene, it provides clear visibility for cell observation and analysis. It is designed for light microscopy and imaging workflows, with emphasis on stable sample placement. Choose this if you require a cost-effective option with good optical clarity and easy handling; avoid if you need the largest possible culture area.
KIESEV Glass Bottom Confocal Dish – φ15mm/φ20mm, 10 Pk
The KIESEV dish is marketed as a glass bottom culture dish compatible with laser confocal setups. The package includes 10 pieces with a 35 mm overall dish diameter, and slide diameters of 15 mm or 20 mm. Constructed from high transparency polystyrene, it aims to provide clear imaging and consistent performance across observations. Best for users who need specific slide diameters for confocal workflows; limitation: variations in bottom thickness may affect focus if not calibrated.
KIESEV Glass Bottom Culture Dish – φ20mm, 10 Pk
Another KIESEV option emphasizes a glass bottom with a slide diameter of 20 mm for focused imaging, supplied as a 10-pack. The product uses high transparency polystyrene and a 35 mm dish diameter, ensuring a larger observation area for culture work. Best for experiments requiring a larger culture surface. Limitation: imaging depth may be influenced by bottom thickness; verify compatibility with objective lenses and immersion media for your setup.
Buying Guide
- Bottom thickness and uniformity: Thicker or more uniform bottoms reduce optical distortion and help maintain focus during imaging. Look for a defined bottom thickness or a specified tolerance.
- Material and clarity: High transparency polystyrene offers good visibility, while borosilicate glass provides chemical resistance and optical stability for certain applications.
- Slide diameter options: Some dishes come with interchangeable slide diameters (e.g., 15 mm, 20 mm). Choose based on your imaging objective and field of view requirements.
- Stability and handling: Designs with minimized width difference between top and bottom hardware improve stability during transfers and mounting in microscopes.
- Compatibility with imaging techniques: For confocal imaging, ensure the dish supports clean optical paths and does not introduce autofluorescence or background noise.
- Sterility and safety: Look for non-toxic construction and safe bonding methods, especially when observing live cells or delicate samples.
FAQ
- What is the ideal bottom thickness for confocal imaging? A thickness around 0.19–0.22 mm provides a sturdy, uniform surface that reduces optical distortion for high-resolution imaging.
- Are borosilicate dishes reusable? Yes, borosilicate glass dishes are typically autoclavable and reusable, making them suitable for repeated experiments.
- Which material offers better clarity for fluorescence imaging? High transparency polystyrene dishes are commonly used for clear visibility, while glass bottoms can minimize autofluorescence in some setups.
- Should I choose a dish with a larger diameter? A larger diameter increases culture area and field of view, which is beneficial for imaging larger samples, but may require a larger microscope stage.
- What if my imaging requires a specific slide diameter? Select a dish with the slide diameter that matches your objective’s field of view and your sample size to ensure optimal imaging.
- Do these dishes come with lids? Some listings mention lids; if you need them, verify lid availability in the product description or packaging details.
