COVID19: Lab Equipment Sterilization Guide

With many of us beginning to move back into the office and classroom as COVID-19 restrictions are being eased, it is more important than ever to ensure that the equipment we and our students are using is disinfected and safe to use. 
 
Please refer to the list below to learn how to clean and sanitize the equipment you have purchased from ADInstruments throughout the years.

#1: PowerLabs, Front-end Signal Conditioners, and Pods.

All models of ADInstruments PowerLabs, Amplifiers, Gas Analyzers, Spirometers, and Pods may be wiped down with a lint free cloth moistened with industrial methylated spirit (denatured alcohol).

#2: Sensors, Electrodes, and Cables

  • All Miscellaneous Cables, Biopotential Lead Wires,  GSR Electrodes, Stimulating Bar Electrodes and Dry Earth Straps:
    • Wipe down with a lint free cloth moistened with industrial methylated spirit (denatured alcohol), a disposable alcohol wipe, or a 70% ethanol spray (wipe off excess spray with a lint free cloth).
       
  • Transducers, Tendon Hammer, Stethoscopes and Cardio Microphone:
    • Clean the body of the sensor or electrode, cable, and connector housing (take care to avoid the actual connection pins) with a lint free cloth moistened with industrial methylated spirit (denatured alcohol) or a disposable alcohol wipe.  Ensure that excessive amounts of liquid disinfectant are not applied to the connector housing or housing of the transducer.
       
  • Respiratory Belt Transducer:
    • Gently clean belt, cable, and connector housing (take care to avoid the actual connection pins) with a disinfectant wipe.  Ensure that excessive amounts of liquid disinfectant are not used on the connector housing.
       
  • Nerve Chamber:
    • Wash with a mild dishwashing soap solution, rinse with tap water, and allow to air dry.
       
  • Infrared Plethysmographs:
    • Clean the body of the sensor, cable, and connector housing (take care to avoid the actual connection pins) with a lint free cloth moistened with industrial methylated spirit (denatured alcohol) or a disposable alcohol wipe.  Ensure that excessive amounts of alcohol are not applied to the connector housing or sensor as this could potentially damage the item.

#3: Respiratory Equipment

During the current COVID-19 pandemic, education respiratory experiments carry a much higher risk than they normally do.  If you still wish to proceed with these types of experiments, we recommend using a new MLA304 Disposable Filter with each student for both two-way and one-way breathing circuit experimental configurations.  The MLA304 filter has a 99.99% viral filtration efficiency, so there still will still be a risk of infection with its use, albeit a small one.  Below are the disinfection guidelines for the equipment items associated with the various respiratory experiments we support.

  • Reusable Mouthpiece:
    • These are considered to be single-use products by the manufacturer.  However, they can be cleaned and sterilized for repeated use by washing the mouthpiece with warm tap water and a mild dishwashing detergent, and then sterilizing the mouthpiece in any consumer-grade steam sterilization device, like those for baby bottles.  
       
  • Gas Mixing Chamber:
    • You can either disassemble and soak or wipe down the chamber with a mild dishwashing soap solution.  Once the item has soaked or been wiped down, rinse the soap solution off with tap water and allow it to air dry. Do not use alcohol or bleach to clean this item as it will damage the plastic it is made from.
       
  • Face Mask Kits:
    • Refer to this online guide.
       
  • Clean-bore tubing and Adapters and Respiratory Flow Head
    • Refer to this online guide.
       
  •  MLA304 Disposable Filter and MLA1008 Nose Clips
    • Replace these items with each subject.

If you have any questions about the procedures outlined above or about the cleaning and disinfection of items not mentioned, please reach out to your local Technical Support Team for further assistance.
