Phase contrast microscopy is the most commonly used, transmitted light technique in cell culture. When working with phase contrast microscopy, it is crucial to have the two phase rings adjusted to each other. In open wells, the meniscus at the air-water-interphase works like a lens that refracts the beam path. This miscalibrates the phase rings, leading to poor contrast in the microscopic image.
Working with the µ-Slide 2 Well Ph+ diminishes the meniscus, so that the whole optical system is aligned, no matter which position of the well is being imaged.
The µ-Slide 2 Well Ph+ (Phase Contrast +) is designed for excellent optical quality, especially for cell culture when normal phase contrast microscopy is being used. Opposed to the classic µ-Slide 2 Well, the Ph+ version provides a special intermediate plate in the center of the well. This plate flattens the meniscus that disturbs the phase contrast effect in normal open wells. Openings near the corners provide access to the wells for the easy filling and aspirating of liquids.
This innovative technique supports meniscus-free phase contrast microscopy in a very convenient manner.

The illustration on the left shows the perturbing effect of a meniscus. Light is refracted on the air-water-interface, leading to poor contrast in microscopy. Only the small center part exhibits satisfying phase contrast.
Working with the µ-Slide 2 Well Ph+ diminishes the meniscus and increases the area of nicely contrasted cells. This nice contrast is due to the parallel beam path that is created by the plate.

"I have done some experiments using the µ-Slide 2 Well and µ-Slide 4 Well for static culture ex vivo, and imaging of intervertebral discs at the IN Cell Analyzer. They work perfectly! Thank you very much, these slides are really very useful, since I have been struggling for some time trying to find the appropriate support to visualize this kind of sample.”

"We tested the µ-Slide 2 Well and µ-Slide 8 Well in the uncoated version for the confocal microscopy of fish larvae. Both types of slides worked fine on our confocal microscope. We have already ordered another bunch of those slides for the lab!"

“The ibidi platforms have opened new possibilities for our group to utilize small volumes of blood to characterize the cell biology of platelets and white blood cells. Moreover, we have greatly benefited from collaborating with the technical representatives at ibidi to discuss ways to multiplex the ibidi platforms to address our experimental questions.”
