The MAGUS SPH1 phase-contrast slider is an accessory for observations using the phase-contrast method. It is designed specifically for the MAGUS Bio V300 inverted biological microscope and works with the MAGUS 20HP and MAGUS 40HP phase objectives.

The slider has three apertures. The side apertures have built-in inserts: one is used with a 20x magnification objective, while the other is for a 40x magnification objective. The central aperture has no insert and is used for brightfield observations. The slider is installed in the microscope’s condenser housing. After installation, the slider apertures must be aligned with the phase rings of the objectives. An auxiliary centering telescope, included in the MAGUS Bio V300 microscope kit, is used for this purpose.

Phase-contrast microscopy is used to study low-contrast living objects that cannot be seen in brightfield. This method does not use staining because it is harmful to microorganisms.
