Testing contact lenses testing presents challenges with the delicacy and small size of the contacts, as well as the required simulated environment.
The testing of soft tissues and various biomaterials in both normal and in vitro conditions can provide important insight into the material properties for research purposes.
When testing the strength and elongation of medical gloves to uphold international and FDA standards, one has to be careful with measuring strain without damage.
Pneumatic grips can be used with testing soft tissue substrates to understand the wound closure strength of tissue adhesives, following ASTM F2458.
To follow ASTM F2516-14, the Advanced Video Extensometer allows for accurate strain measurement of Nitinol wire for biomedical uses without common failures.
Tensile testing of catheter tubing with pneumatic cord and yarn grips determines the breaking strength for quality control. Tortuosity testing of catheter tubing enables researchers to quantify the frictional forces during insertion and removal of medical tubing.
Instron's syringe test fixture works for various specifications and follows ISO 7886-1 to test the aspiration and injection of liquids.
Tests to determine the bond strength and tensile adhesion of materials in restorative dentistry can be created using a 5900, 3300, or ElectroPuls test instrument.
Instron's Bath and Submersible Pneumatic Grips can assist in in-vitro testing of soft tissues and biomaterials, which are fragile and require low force measurements.
Orthopedic micro-implants used to treat bone problems and soft tissue injuries need to be tested in simulated loading conditions to prevent failure.
For tensile testing of polymeric membranes for the biomedical field, challenges are associated with gripping the wet specimens without slippage or tearing.
Non-contacting extensometers can be used to measure strain of biological specimens without early damage, and various techniques can be used to mark the soft tissues.
Instron's XY Test Stage mounts to various universal testing systems to work as a precise force applicator without touching the wrong components.
