Our expert comment:
Expert commentary by Prof. Dr. Guido Posern, Director Institute of Physiological Chemistry, Medical Faculty, Martin Luther University Halle-Wittenberg:
"I have a very good impression. Assembly is simple. Everything works, with the exception of the attached setting eyepiece (I can't see anything with it; possibly wrong model, but it's not absolutely necessary either). The phase contrast is impeccable in all three lenses for standard cell cultures of mammalian cells. The phase plates are correctly tuned and clearly labeled. So far I can't find any disadvantages compared to our other, sometimes much more expensive ones. Brightfield is not very relevant for us, but apparently it also works OK. Whether the robustness of student use can withstand it has to be seen, but so far the device makes a solid and easy to operate impression.
Conclusion: an excellent cell culture microscope for standard applications in research with a top price-performance ratio!"
