Attention! Disconnect the mains plug before cleaning and servicing! Protect electrical components from humidity!

In warm and humid climates, microscopes require special care to prevent fungal growth.

Clean the microscope after each use and make sure to keep the microscope immaculately clean.

Note: Protect the microscope and its accessories from dust by putting on the dust cover after each work session.

Attention! Fibre and dust residues can cause disturbing background fluorescence during fluorescence microscopy.

Dust and loose particles of dirt can be removed with a soft brush or lint-free cotton cloth.

Obstinate dirt can be removed with commercially available aqueous solutions, benzine or alcohol.

To clean painted parts, use a linen or leather cloth moistened with any of these agents.

Attention! Do not use acetone, Xylol or nitro dilutions which can damage the microscope.

Warning: Observe the safety instructions for immersion oil!

Wipe off the immersion oil with a clean cotton cloth
