Phase contrast and brightfield microscopes provide options for observing live cells depending on your applications. A complete set of phase contrast kit can be flexibly equipped with an ordinary biological microscope to be a phase contrast microscope system. The phase contrast microscope can improve the images of transparent and colorless objects, which are hard to see or invisible in an ordinary microscope. The compound Siedentopf trinocular microscope comes with trinocular viewing head, body frame, quadruple reversed nosepiece, four DIN achromatic objectives, large double layer mechanical stage, variable intensity halogen transmitted illumination system and a set of phase contrast kit. It offers eight levels of brightfield magnification 40X-1600X. The phase contrast kit includes a phase contrast NA1.25 condenser, a centering telescopic eyepiece, three achromatic phase contrast objectives with phase plate: 10X, 40X, 100X. The phase contrast biological microscope offers six levels of magnification power: 100X-160X-400X-640X-1000X-1600X. This phase contrast compound microscopy is perfect for clinical, university or institutional uses.
