Protection from dirt

Dust and dirt will affect the quality of your results.

★★ Put a dust cover over the microscope when it will not be used for a long time.

★★ Use dust caps to protect tube openings, tubes without eyepieces, and eyepieces.

★★ Keep accessories in a dust-free place when not in use.

Cleaning polymer components

Some components are made of polymer or are polymer-coated. They are, therefore, pleasant and convenient to handle. The use of unsuit- able cleaning agents and techniques can damage polymers.

Permitted measures

★★ Clean the microscope (or parts of it) using warm soapy water, then wipe using distilled water.

★★ For stubborn dirt, you can also use ethanol (industrial alcohol) or isopropanol. When doing so, follow the corresponding safety regulations.

★★ Remove dust with a bellows and a soft paintbrush.

★★ Clean eyepieces and objectives with special optics cleaning cloths and pure alcohol.
