Peak Tensile Force / Tensile Bond Strength

Tensile test (uniaxial) to determine the bond strength at locations where adhesives, thermal fusion, or other joining methods are used for bonding components of the delivery system.

Also known as catheter bond strength.

Test Procedure

All bonds must withstand tensile forces greater than those that may be experienced during clinical use.

A tensile tester is used. A part of the catheter is held by the stationary jaw of the machine. Each catheter junction is placed on the tensile tester and pulled at a uniform rate of displacement until rupture. Peak tensile force is recorded.

ViVitro Labs Advantages

Many companies look to academia to handle their testing needs due to the reduced cost. With ViVitro Laboratory Services you gain the following advantages:

ISO 17025 Accredited
For studies used for regulatory approval this is a must. Victoria and Marseille labs accredited by A2LA.

Test Method Validation
The FDA and Notified Bodies around the world are requiring evidence of Test Method Validation. ViVitro Labs has invested significant resources to validate the most common test methods that are not ISO 17025 accredited. We continue to work closely with device manufacturers and share the burden with our clients to validate other specific test methods that are less in demand.

We understand how critical your timelines are. Our expertise and experience ensure your schedule is met and our commitments are delivered on time.

Free Initial Consultations
All of our studies are scoped via no-cost, no obligation, collaborative consultation.

Guaranteed Confidentiality
We happily provide Non-Disclosure Agreements for all services, including initial consultation.
