Plates and dishes for imaging

For best quality imaging, you want to use a 170 μm (0.17 mm) coverslip. This is roughly equivalent to a #1.5 coverslip. There are also plate and dish options which use a plastic polymer instead of a coverslip. When choosing a polymer bottom pay attention to the thickness of the polymer, since anything thicker than a coverslip will reduce the working distance of the objective and can prevent you from using high NA objectives. Also standard PS tissue culture plasticware can be imaged through but you will not have good performance and is really only acceptable if you just need low resolution images. The following are sources of imaging dishes and plates we are aware of.


35 mm Petri Dishes


Chambered Coverglasses / Slides

⚠️ NOTE: MatTek is popular for 35 mm dishes, but the Chambered Slides they sell are not able to be viewed through the bottom (they have a 1 mm thickness) and should not be used for live imaging. You must remove the wells and coverslip these slides.


Multi-well Plates

There are a large number of multi-well plates designed for imaging available that vary in cost, mostly determined by the material the bottom of the plate is made of. There are some important details to pay attention to when deciding on a plate to make sure that you will be able to capture the images needed for your experiments. In general you want a flat-bottom plate with black sides to help keep background fluorescence and light scattering minimized.

  1. Glass bottom vs Polymer bottom — Glass bottom plates will give the best performance and should be used if you plan on using a 40x or higher magnification objective. For standard screening the polymer bottom plates can provide good performance at a lower cost, but pay attention to the thickness of the polymer. Some polymers can be more than 300 µm thick, which will limit the objectives that can be used due to working distance issues.

  2. Height of plate skirt — Plates with a tall skirt can prevent you from focusing on the edge wells with some objectives. If you need to use a higher NA objective be sure to test your plate to make sure that you can access the edge wells. Several manufacturers have plates available with almost no skirt.


Specialty Products


Many companies can provide a sample of the different dishes and plates. If you are unsure of what you need, this can be a useful way to test performance of the plates on your samples.
