ADMET’s eXpert 8900 series determines durability of biomaterials
How materials testing meets international regulations for the medical device market
European lawmakers are considering new regulations for managing the development of medical devices and implants. This is due to the after-affects of several defective devices hitting the market. Materials testing is one important step for ensuring the safety of all heart stents, bone screws and other biomaterials. ADMET offers a multitude of testing machines for the biomedical market.

ADMET’s BioTense bioreactor helps researchers study cell adhesion and extracellular matrix motion
Medical device testing: Internal fixation vs. external fixation
Both internal and external fixation devices assist in proper bone healing. Despite this similarity, differences exist between devices and this is reflected in how they are tested.
ADMET testing machines are capable of multiple methods of testing fixation devices. This includes simultaneous Torsion and Tension testing and Torsion testing with a pulley counter balance weight. Read more.
MIT researchers working to develop biomimetic medical adhesive
Researchers at MIT, led by Professor Jeffrey Karp, are looking into the remarkable adhesive properties of Gecko feet in an effort to develop better adhesives for biomedical applications. They’re using an ADMET eXpert 7601 Universal Testing Machine to aid them in better understanding the forces at work.
ADMET’s BioTense bioreactor used in Northeastern University cornea research
Researchers at Northeastern University are studying the effects of mechanical strain on cells to see if they can induce the cells to produce corneas for human transplant. An important aspect of their research is use of ADMET’s BioTense perfusion bioreactor, a state-of-the-art device that allows the team to apply strain while permitting simultaneous study via a microscope.
Pipette tips: Determining stiffness with a bend test
How does discovering the mechanical properties of a product help determine the process for manufacturing? An ADMET Customer presented us with a problem. Their plastic disposable pipette tips lacked sufficient stiffness to ensure the customer’s success in dispensing fluids.
Revolutionizing the bone screw industry- Bioceramics
The University of North Carolina Charlotte is making great strides in discovering the mechanical properties of their bio-absorbable material. In addition, news coming from the University of Bremen states that their new material will revolutionize the bone screw market. What’s so special?
How do you test spinal implants?
ADMET’s mechanical property testing systems have proven to be accurate and reliable. This is especially true for medical devices manufacturers, where the company’s universal testing systems, help surgeons and doctors all over the world make decisions for their patients based on mechanical property data. The mechanical property data exhibits tensile strength, bend strength, fatigue/durability, torsional capacity, and reliability for a number of devices.
ASTM F543 Annex 3 Axial Pullout Strength Metallic Bone Screws
Metallic Bone Screws- Which one, where, how….
Metallic bone screws are implemented in many applications within the body. Screws stabilize the bone while it heals. Standardization of the dimensions and tolerances of the key features of these screws is intended to allow the implants from one manufacturer to be used with associated instruments, such as taps and drills, from different manufacturers and serve as a baseline for future screw products.
