Disinfection and decontamination:  

• 

Exterior casing and mechanical surfaces must be wiped with a clean cloth, dampened with a disinfectant

• 

Soft plastic parts and rubber surfaces can be cleaned by gently wiping a clean cloth, dampened with a 
disinfectant. Discoloration can occur if alcohol is used

• 

The front lens of eyepieces and objectives are sensitive to chemicals. We recommend not to use aggressive 
disinfectants but to use lens paper or a soft fiber-free tissue, damped in cleaning solution. Cotton swabs may 
also be used. We recommend you use personal eyepieces without eyeshades in order to minimize risk 

• 

Never immerse or dip the eyepiece or objective into a disinfectant liquid! This will damage the component

• 

Never use abrasive compounds or cleaners that may damage and scratch optical coatings 

• 

Properly clean and disinfect all possible contaminated surfaces of the microscope or contaminated accessories 
before storing for future use. Disinfection procedures must be effective and appropriate

• 

Leave the disinfectant on the surface for the required exposure time, as specified by the manufacturer. If the 
disinfectant evaporates before the full exposure time, reapply disinfectant on the surface

• 

Against bacteria, use a 70% aqueous solution of isopropanol (isopropyl alcohol) and apply for at least 30 
seconds. Against viruses, we recommend to refer to specific alcohol or non-alcohol based disinfection products 
for laboratories 

Before returning a microscope for repair or maintenance through a Cole-Parmer dealer, an RMA (return authorization 
form) together with a decontamination statement must be filled in!  This document must be shipped together with the 
microscope at all times.
 

Handle with care

• 

This product is a high quality optical instrument. Delicate handling is required

• 

Avoid subjecting it to sudden shocks and impacts

• 

Impacts, even small ones, can affect the precision of the instrument

Handling the LED 

Note:

 Always disconnect the power cord from your microscope before handling the LED bulb and power unit and 

allow the system to cool down approximately 35 minutes to avoid burns

• 

Never touch the LED with your bare hands

• 

Dirt or fingerprints will reduce the life span and can result in uneven illumination, lowering the optical 
performance

• 

Use only original MSU-100 Series replacement LEDs

• 

The use of other products may cause malfunctions and will void warranty

• 

During use of the microscope the power unit will get hot; never touch it while in operation and allow the system 
to cool down approximately 35 minutes to avoid burns

Dirt on the lenses

• 

Dirt on or inside the optical components, such as eyepieces, lenses, etc., affects the image quality of your system 
negatively

• 

Always try to prevent your microscope from getting dirty by using the dust cover, prevent leaving fingerprints 
on the lenses and clean the outer surface of the lens regularly

• 

Cleaning optical components is a delicate matter. Please, read the cleaning instructions further on in this 
manual
