Repairs

Effective January 1, 2025, all repairs, recertifications, and returns must fill out the form on our Form Submittal Page (https://www.martekinstruments.com/pages/services) and submit it to us prior to returning any equipment. While we do not require a Return Material Authorization Number, if you would like to use one for your own records, you can use the day of submittal by utilizing a day/month/year format. For example: 01062025.

Please note, we will no longer accept returns or repairs without a Submittal Form. By following the new Submittal Form Policy, we will be able to better control the inflow and processing of repairs and/or recertifications in order to provide a quicker turnaround.

Return, Repair, Recertification Form can be found HERE
