* CLEANING GUIDELINES *
External Cleaning / Disinfecting Instructions
For any BIOPAC Systems data acquisition, amplifier, or accessory module:
- To clean the surface of the module:
- wipe lightly with a dry, lint-free cloth, or
- wipe lightly with a soft cloth dampened with a commercial, non-abrasive cleaner, or
- use a low-pressure air line to blow dust free, or
- carefully clean with a suitable vacuum cleaner.
- To disinfect the module: wipe the surface with a soft cloth dampened with a solution of 70% alcohol in water.
! Warning Do not spray, pour or spill any liquid on the module, including its connectors, switches or openings.

Facemask
See AFT25 Facemask Cleaning & Sterilization.
fNIR Imagers and Sensors
All generations and models: Use an alcohol-based antiseptic to gently wipe the surface of the fNIR Imager unit or sensor; never use peroxide-based antiseptics.
FOTS100
FOTS100 system or TSD180/TSD181 FO Probes: see FOTS Cleaning Guide
GAS ANALYSIS SYSTEMS
GASSYS2-EA or GASSYS2-EB System or  RXGAS-Aand RXGAS-B Chambers: See GasSys2 Cleaning & Disinfection – use only Cidex!
Gold Cup Reusable Electrodes (EL160)
After each use (earclips and surface electrodes), clean with warm water and a mild detergent, using a soft cloth or Q-tip. Subsequently, disinfect electrode with a water-based disinfectant. Before use, check the electrode for damage caused by excessive wear. If in doubt, replace the electrode.
Leads (shielded and unshielded)
To clean electrode leads:
Clean electrode lead with 70% isopropyl alcohol. Electrode lead can be fully immersed in alcohol and/or wiped down. Do not store the electrode lead in an alcohol or water solution. Dry the electrode lead prior to reuse.
To disinfect electrode leads:
Use liquid cold sterilization (detailed below).
Liquid “COLD” sterilization
When liquid cold sterilization is specified for a BIOPAC transducer, the following disinfectants are recommended:
-
Cidex OPA Disinfectant Solution, Johnson & Johnson
-
Perform Powder Disinfectant Concentrate, Schamp; Mayr
-
Terralin, Liquid Disinfectant Concentrate, Schamp; Mayr
IMPORTANT: Always follow the manufacturer’s directions.
Needle Electrodes (Reusable)
Vacuum: 40.64 cm Hg
Relative Humidity: 50% +/- 10%
Humidity dwell: 77 minutes
EO gas: 12/88 Oxifume
Gas Exposure rise: 12 psig
Exposure time: 105 minutes
Probes
! Some temperature probes are non-sterilizable and sensors should be replaced as necessary:
Non-sterilizable temperature probes include:
• Fast-response surface temperature sensor: TSD202A and SS6L (use replacement sensor RX202A)
• MR Conditional surface temperature sensor: TSD202A-MRI (use replacement sensor RX202A-MRI)
• General-purpose waterproof thermistor: TSD202E and SS7L
• Flexible waterproof thermistor: TSD202F and SS8L
Immersion temperature probes may be cleaned using standard liquid disinfectant methods, with direct immersion for the recommended period.
Wipe down non-immersion probes with liquid disinfectant or alcohol.
Reusable Electrodes/Transducers
- EL120 reusable electrodes
- EL254 and EL258 Â reusable electrodes
- EL654 and EL658 reusable electrodes
- TSD203 and SS3LA Skin Conductance Transducers
GEL should immediately be cleaned off the electrodes after each use. Dried gel will act as an insulator decreasing electrical contact with the skin, and the Ag-AgCl electrode disk could degrade quickly with time because of the porous electrode surface.
To clean the electrodes
- Wet a cotton swab or toothbrush with water and remove the electrode gel.
- If needed, use Hydrogen Peroxide solution (2-3%) to brighten electrode surface (optional) or to sterilize the electrode; do not place the electrode in solution, but rather use a cotton swab or toothbrush.
- Always dry the electrodes after cleaning.
- If a dark residue remains after the above cleaning methods are used, then a cleaner with pumice can be used on the wetted cotton swab or toothbrush.
Warning! Use of a Waterpik® or similar jet will drastically shorten the life of these electrodes and is not recommended.
RX117A and RX117A-MRI Flow Heads
Used in SS11LB, SS11LA, TSD117A, TSD117A-MRI pneumotachs
Recommended sterilization: cold sterilization (i.e., Cidex® OPA)
RX137 Series Pneumotach Flow Heads
used in TSD137 Series and SS46L-SS52L
See recommended Cleaning, Disinfection/Sterilization and Maintenance (PDF)
Thermoplastic rubber mouthpieces and couplers
Mouthpieces and couplers are supplied non-sterile and should be sterilized before use for pulmonary equipment interconnects.
-
Autoclaving – preferred method
250°F for 14 minutes or 240°F for 23 minutes -
Ethylene Oxide 125-131°F
Ethylene oxide aeration time is greatly dependent on the size of the master carton and its permeability. One week is the minimum requirement to bring the EtO residuals below 1 PPM as tested by the standards liquid extraction method. If the product is heated to 123-135 F in an aeration chamber with high airflow, the time can be accelerated to as little as four days.
Inspect after sterilization for deterioration. Dispose if damaged.
