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.
Pneumatic side action grips or mechanical elastomeric grips may be used in testing the physical properties of medical gloves, according to BS EN 455-2.
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.
Testing contact lenses testing presents challenges with the delicacy and small size of the contacts, as well as the required simulated environment.
The bond strength between the needle and the syringe barrel is a critical component test for the safety of both the patient and the handler
Instron's syringe test fixture works for various specifications and follows ISO 7886-1 to test the aspiration and injection of liquids.
Many soft tissues, such as skin or collagen, are delicate specimens with low ultimate strength values and require a testing system to be highly sensitive to low-force measurements and small displacements.
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.
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.
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.
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.
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.
