This procedure is to be used for materials and instrumentation destined for return to PerkinElmer Life and Analytical Sciences for repair, maintenance, warranty or trade-in purposes. Potentially contaminated equipment can not be approved for return from a customer until it is certified as “clean”. A complete decontamination must be performed on all equipment suspected of being contaminated. The PerkinElmer customer/user certification form should be used to certify the equipment as “clean”, or that the required decontamination process has been completed. The certification form should be signed off and attached to the outside of the box in a “shipping docs” bag. In the event questions arise regarding the applicability of the decontamination and certification process for returned parts and accessories, please call your local PerkinElmer representative.
