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, the Advanced Video Extensometer allows for accurate strain measurement of nitinol wire for biomedical uses without common failures.
A 5948 MicroTester can be used to determine the strength of bioadhesives to be sure that a correct concentration of drugs is delivered into biological substrates.
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.
For testing polymer hydrogels, use an electromechanical test system with a 50 N load cell, pneumatic or manual screw action grips, and a dog bone die.
For tensile testing of polymeric membranes for the biomedical field, challenges are associated with gripping the wet specimens without slippage or tearing.
Pneumatic side action grips and rubber coated jaw faces work for tensile testing thin human hair to understand the results of various shampoos, dyes, and gels.
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.
