Automated testing of Suture Materials

In our previous featured post Automated Testing: Are You Doing It?, we talked about the benefits of using automation for your material testing needs, such as increased profitability and improved quality thanks to streamlined testing procedures.

In this video, we would like to show a specific example of Automated Testing where the system is configured to perform unattended tensile testing of biomedical suture specimens.



A typical automated test sequence includes the following steps:
- The robot retrieves a batch separator with a barcode label affixed from a rack, scans the barcode, and downloads the specimen and testing information to the Testmaster2 Automation Control Software.
- The separator is then discarded into a bin and a specimen is retrieved from the racks and placed into the tensile frame and tested.
- After the test, the specimen is removed via a specimen removal device at the back of the frame, which utilizes a low-noise, industrial vacuum to aid in full removal of the tested sutures from the grips area.
- The robot then inserts the next specimen to be tested.

Do you think automated testing is a good solution for labs? Leave us a comment to discuss!

Nice! At time 2:10 of the video the robot passes the suture specimen through what looks like a non-contacting sensor. Is that thickness measurement?

Thank you for your question!. That sensor confirms that a specimen has been retrieved by the robot arms but it does not provide measurements. If the specimen is not present, then the robot will return to the racks and retrieve the specimen located in the next position.
