All Kaha Mouse Telemeters are shipped sterilized using ethylene oxide gas sterilization and can be implanted without the need for further sterilization. Telemeters will remain sterile as long as the pouch is intact and not compromised. It is recommended that they remain in their original packaging until surgical implantation.
However, if the telemeters have been accidently removed from the sterile packaging prior to implantation, or if they come in contact with non-sterile surfaces during surgery, they can be resterilized:
Chemical Sterilants
Glutaraldehyde may be used to sterilize the telemeters. Glutaraldehyde (Fisher Scientific) must be diluted to 2% in sterile pyrogen-free water or sterile 0.9% saline before use. Do not use gluteraldehyde solutions containing surfactants (i.e. do not use Cidex 7, Cidex Plus 28 Day or Metrocide 28) or hydrogen peroxide. Suitable products are in the table below:
IMPORTANT:
- Telemeters sterilized with a chemical sterilant should always be washed thoroughly in sterile saline before implantation to remove all traces of the sterilant.
- Some examples of chemicals that will cause damage to telemeters include, but are not limited to: alcohols, phenols, iodophors, and hypochlorite. Please confirm with our support team before using any product other than the approved products list above.
- Products with similar names are available, but may not be suitable. Please use only products specified or contact our support team for clarification.
Ethylene Oxide Gas Sterilization
Telemeters are suitable for Ethylene Oxide sterilization as long as they are not subjected to temperatures above 60°C.
IMPORTANT:
- Under no circumstances should the telemeter be autoclaved or subjected to temperatures over 60°C as this will damage the telemeter.
- Do not sterilize by radiation (gamma or e-beam), plasma, alcohol, peroxide or formaldehyde vapor solutions. This will damage the telemeter.
