Recommended Handling and Disinfecting Procedures for Nikon Microscope products to reduce spread of infectious agents including SARS-CoV-2 (Coronavirus)
abr. 16, 2020
This letter provides recommendations for Handling and Disinfecting Nikon Microscope Products to reduce the spread of potentially infectious agents including SARS-CoV-2 (Coronavirus; causative agent of COVID-19).
Note: This instruction is based on current global medical standards and may be updated as needed.
Recommendations for General Handling and Disinfection
Please follow the instructions or guidance issued by your local medical authorities and relevant organizations such as WHO *1.
Please wear appropriate Personal Protective Equipment (PPE) such as disposable gloves, gowns and goggles based on the result of infectious risk assessment in your facilities.
If your Nikon microscope systems include cameras, consider using the camera view instead of eyepieces for specimen visualization.
The following tables describe compatibility of WHO-suggested disinfectants*1 with Nikon microscope products.
Excerpt from “c. Use of appropriate disinfectants” section in the WHO guidance*1
“While little is known about this novel virus, the comparable genetic characteristics between the virus responsible for COVID-19 and MERS-CoV suggest that the COVID-19 virus may be susceptible to disinfectants with proven activity against enveloped viruses, including sodium hypochlorite (bleach; for example, 1000 parts per million [ppm] (0.1%) for general surface disinfection and 10000 ppm (1%) for disinfection of blood spills); 62–71% ethanol; 0.5% hydrogen peroxide; quaternary ammonium compounds; and phenolic compounds, if used according to the manufacturer’s recommendations. Other biocidal agents such as 0.05–0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate can be less effective.”
Of the above listed disinfectants, 70% ethanol is safe to use for cleaning Nikon microscope products, Use 70% ethanol for the purpose of disinfection. Frequent disinfection is highly recommended.
Table 1. Compatibility of 70% EtOH with Nikon Microscope parts
|Microscope Parts*2,3||70% EtOH||Note|
|Eyepieces||Compatible||Moisten lens cleaning tissue with 70% ethanol and wipe the surface of the lens and rubber gaskets (if present on eyepieces). For more detailed objective lens cleaning procedures, please download our “How to Clean Objectives” document from our website.|
|Body||Compatible||Moisten low-lint lab tissue with 70% ethanol and wipe the surface.|
*2 Internal optical components and filter cubes should only be cleaned by Nikon-authorized service technicians.
*3 Pay special attention to commonly touched parts of the microscope such as focus knobs, nosepieces, and stage handles when cleaning.
According to WHO guidance*1, disinfectants which are listed in Table 2 below may also be effective against COVID-19 virus. However, these disinfectants may negatively affect the material and performance of Nikon products. Therefore, DO NOT use the disinfectants listed in Table 2 for Nikon microscope products. Use 70% ethanol instead.
Table 2. Disinfectants that are not compatible with Nikon Microscope parts
|Eyepieces||Sodium hypochlorite (bleach; for example, 1000 parts per million [ppm] (0.1%) for general surface disinfection and 10000 ppm (1%) for disinfection of blood spills); 0.5% hydrogen peroxide; quaternary ammonium compounds; and phenolic|
compounds; 0.05–0.2% benzalkonium chloride; 0.02% chlorhexidine digluconate.
|Objective Lens||NOT COMPATIBLE|
